Storage tank for water in the apartment. Storage tank for water supply: water supply scheme, volume and design of the tank, installation of water supply

Before choosing a water tank, you should definitely determine the optimal volume of the tank, taking into account the composition of the family and its needs. In a private house, this issue is solved somewhat easier, since utility rooms can be used. For an apartment, the volume of the tank can vary from approximately 100 to 300 liters.

Before buying, you should definitely decide where the water storage tank will be placed in the apartment, and how it will be installed, especially taking into account the weight of the filled tank. As a rule, the so-called dead zones in the house are used for this, you can also consider installing a tank, for example, under the ceiling in the hallway, corridor, bathroom or even in the kitchen. In the event that a sufficiently large capacity is installed, then it is best to choose floor options, but for an apartment, you should still give preference to mounted models. In this regard, it is important to pay attention to the shape of the product: for an apartment, cylindrical or flat tanks will be the best option.

The way the tank is connected is also determined by its location:

⦁ if the tank is mounted on a hinged way, then water is taken from it under the action of gravity forces;

⦁ for floor models, the water supply is provided by a circular pump, which creates and maintains a certain pressure;

⦁ for membrane-type tanks, the installation location does not matter, due to the fact that required pressure and the pressure for supplying water to the water supply network is created due to the presence of an air chamber.

Even if the need to use reserve water supplies is rare, it is necessary to provide periodic circulation to avoid stagnation, in addition, a tank cleaning procedure will sometimes be required, especially if the water quality is not ideal.

In modern times, an autonomous water supply system is a fairly common design. This is due to the lack of centralized water supply in many suburban settlements built not very long ago. To install such equipment, you will need to purchase a storage tank that can hold a certain amount of water and provide full pressure at any time of the day.

General characteristics of storage tanks

Not all residents of suburban settlements can easily solve the issue of water supply due to the lack of a nearby water source to which a pumping station could be connected. In such cases, the storage tank is an indispensable device that performs the functions of a battery.

During the period when water consumption is minimal, the barrel is gradually filled with water in order to supply it to the water supply network at the time of maximum consumption. In order to ensure that during its installation and connection to common system there were no difficulties, you should carefully read the principles of this design.

Device and specifics

Thanks to the storage barrel, the required pressure is maintained in the water supply system. Usually, for such purposes, closed membrane-type equipment is installed, which is made in the form of a container with a rubber membrane located inside. This plate divides the tank into two compartments, one of which is a space consisting of air, the other is filled with water.

The membrane has the properties, on the one hand, to collect an ideally pure liquid, and on the other, a composition supersaturated with impurities. This process is called reverse osmosis.

The water supply facility is operated in autonomous networks supplying both hot and cold water. In the event of a lack of liquid in the main resource, the storage tank replenishes it from its reserves. The tank is a container made in different options and volumes. It has nozzles for the inlet and outlet of water, as well as devices for its purification in the form of filters and a ventilation system. Higher cost models are equipped with pumping systems.

Control over the level of liquid in the barrel occurs by means of electronic and float devices for determining the level built into the device. From the main source, water is pumped by a pumping station into a storage barrel, fills it to a certain level, and then, due to actuation of a valve equipped with a float, the water intake procedure is completed.

The fluid chamber is filled after the pump electric motor is started, and the air chamber is reduced in size. The amount of air depends on the amount of pressure, which increases with its decrease. After the collected water reaches a certain level, the pump automatically turns off. Its inclusion occurs only after the pressure is reduced to a minimum, and the liquid at this time is supplied from the water compartment.

The operation of the pump (switching on and off) is carried out automatically, and thanks to the built-in pressure gauge, pressure is controlled. After undergoing purification and aeration, the liquid is supplied to the water supply structure, where it is regulated by faucet. The storage tank performs several functions simultaneously:

• after the pump stops working, it stabilizes the pressure;
• when air or power surges enter the water supply system, it creates protection against hydraulic vibrations;
• maintains a certain volume of water;
• prolongs the life of the pump.

Due to the reserve of water in the storage barrel, there is no shortage of it, and with low consumption, it is not necessary to put the pumping system into action.

Product varieties

Storage tanks can differ from each other in the following ways:

1. 1. The configuration, which is round, in the form of a cylinder or rectangle, or non-standard.
2. 2. Construction type. Models open type with or without a lid and completely closed.
3. 3. Material used in production. Tanks are made of polypropylene, plastic, stainless steel or metal.
4. 4. Volume from the inside. Tanks are both small (from twenty to thirty liters) and large (from fifty to ten thousand liters).
5. 5. Appointment. Reservoirs are used for the purpose of cold and hot water supply, irrigation, creating a water supply, and are also included in the construction of a summer shower made on their own.
6. 6. Mounting option for both horizontal and vertical types underground or on the surface.

Tank models made of plastic, are considered more in demand because of their practicality. They are distinguished by their unpretentious manufacture, low weight and at a small price.

Although larger tanks take significantly longer to fill, they are a more economical option as they allow the pump to be turned on less frequently.

Stainless steel barrels are resistant to mechanical failures and corrosion, this is due to their considerable cost, often such models are made to order.

The method of installing storage tanks with a lower location contributes to the appropriate use of the usable area. This case implies the presence of a pumping system for supplying water to private house or bath. With this arrangement, water is pumped into the accumulator with the help of a pump with the simultaneous formation of an air layer.

When the liquid reaches the prescribed level, the air forcefully displaces it to the intake points. Often, in order to achieve the optimal pressure in the process of water supply, a submersible drainage pump, the float of which is installed inside the storage tank.

If the tank with the lower location is planned to be operated in winter time, then its penetration into the ground should be carried out below the level of its freezing. In addition, high-quality insulation is also produced. The reservoir of a water supply system used only in summer is usually located at a depth of no more than 50 centimeters from the topsoil.

The scheme of the upper location of the tank assumes its installation at the maximum permitted height. It can be on the terrace, attic or under the ceiling, in winter period it also warms up. The location at the top is able to provide excellent water intake without the use of a pumping system and provides safe operation tank.

Purpose of the tank

In modern times, residents need to have not only round the clock supply water, but also an ideal pressure that satisfies the requirements of water folding equipment. To ensure such water supply, storage tanks are built into the system, which are installed even in an apartment. Such a decision is predetermined by the following cases:

1. 1. On the site of a summer residence or a private house, there are no sources of water supply, and their arrangement is not possible. The storage tank in this situation will be regularly filled from a tank truck.
2. 2. Despite the presence of a centralized water supply, there are systematic interruptions of water or the supply is made according to a particular schedule.
3. 3. Own water well or another source is not able to meet the needs of residents at any time, which leads to water shortage due to long and continuous withdrawal.
4. 4. For some reason, frequent power outages occur, causing the pumps to stop working.

In each of these situations, the water reserve accumulated in the tank will eliminate uncomfortable conditions due to its absence for a certain period (depending on the volume of the tank).

Criteria for the right choice

If there are two or more floors in a private house, the storage tank is installed in the attic, which makes it possible to exclude the arrangement of the pumping system. But at the same time, for optimal pressure, it will be necessary to place the equipment at a certain height, followed by the installation of a device for heating water in order to avoid freezing in winter.

When choosing a storage tank, it is necessary to carefully study all its characteristics. The capacity of the container should be optimal for the number of people to whom it is intended for the purpose of water consumption. It is very important to consider the number of areas in the room that take water, for example, household appliances, taps and showers. In addition, it is worth considering the possibility of simultaneous consumption by several water consumers at once.

When choosing a storage tank, you should analyze the performance of an autonomous resource or the operation of a centralized system. If the supply of electricity or water stops for two or three hours, then a barrel with a volume of one hundred liters will be able to compensate for these inconveniences. In case of frequent shutdown utilities you will need a container with a much larger displacement.

It makes no sense to purchase and install a tank with a volume of five cubic meters, if during the day the well can fill it with no more than five hundred liters.

When considering the material for manufacturing, you need to remember that tanks made of metal or stainless steel are mainly designed to create a reserve of hot water. And since they are expensive, it makes no sense to purchase them for storing cold liquid. For this purpose, the optimal barrels made of polypropylene marked for food products. Particular attention must be paid to the quality of the product, since plastic, which has an odor, can only be suitable for storing process water.

Top mounting

The installation of a tank in the attic is considered as the most common solution in the process of arranging an autonomous water supply structure in a private house, in a country house or in a bathhouse. For this purpose, it is required to purchase a container having the required volume and shape, the installation of which will be carried out on a beam ceiling located at the top. If this place is inconvenient for residents, then the storage tank can be located in any suitable part of the attic.

The installation event includes several stages:

1. 1. The base on which the tank will be located is strengthened, boards with the required width are superimposed on top of the floor beams.
2. 2. A storage tank is installed on the prepared base.
3. 3. The float valve is being installed, an indent of 7.5 cm is made from the upper edge, and a hole with the required diameter is cut in the marked place. After that, a part of the valve is passed through it from the tail side, equipped with a plastic washer for sealing. In the meantime, a rigid plate and a similar sealing washer are mounted on the opposite side of the tank, and then a nut is screwed on. All fasteners must be fixed with high quality and a connector, which is an intermediary between the tank and the water pipe, must be attached to the tail section.
4. 4. Holes with the appropriate size are made for the installation of the outlet pipes. In holes located on inside tank, a connector with a washer is screwed in. In order to secure the thread, you should use a special tape, and then put on the washer and tighten the nut.
5. 5. Shut-off valves are placed in the outlet pipes.
6. 6. An overflow is carried out, for which a mark is fixed, located two and a half centimeters below the float valve, after which a hole is made.
7. 7. The pipe, in case of overflow, is led into the sewerage system and attached to the walls of the container by means of connectors in a similar way. After that, pipes with compression clamps are brought in. The prepared parts of the piping system are attached to the walls of the tank and to the wooden base.
8. 8. The attached storage tank is filled with liquid to test the system for leaks and adjust the float valve.
9. 9. The tank is insulated using polystyrene or mineral wool.

Installing a tank in the ground

Before proceeding with the installation of the tank, using the option with a lower location, you should choose the most suitable place for this. In this case, it is recommended to purchase designs with a round configuration, in addition, it is worth emphasizing the stiffening ribs necessary to improve the mechanical characteristics and ideal installation of the device.

When installing a storage tank that has a different shape and without ribs, then for correct installation a concrete shell will be required. With its help, you can qualitatively fix the device in the ground.

The part of the structure located on top must be equipped with a special hole made in the form of a hatch. This will allow you to periodically monitor the condition of the equipment from the inside. The slope of the storage tank should not exceed fifteen degrees, which will make it possible to clean it without applying special efforts.

At the end of the work, an expansion tank (hydraulic accumulator) is connected, designed to compensate for the pressure inside the system.

Installing a storage tank is not a complicated procedure and provides an opportunity throughout the year not to depend on the water supply schedule of a centralized water supply system.

Every owner of a private house sooner or later thinks about installing an autonomous water supply system. The point is that most country cottages for many years they did not have a centralized water supply system. As a result, homeowners have only two options: install a storage tank or continue to carry water in a bucket.

Of course, the romance of country life has its merits. But the lack of water in the house does not apply to them. This is a huge drawback that spoils all the pleasure of staying in a private house. The installation of a water supply system with a storage tank fundamentally changes the situation.

You braid the house with pipes and get hot water wherever needed. True, in order for this to become a reality, it is necessary to install a boiler in the water supply system of a private house with a storage tank.

The purpose of the storage tank

This device cannot be called too complicated. Nevertheless, it is indispensable in the water supply system of a private house. As the name implies, a storage tank is used to store water. Imagine a situation that you still have water to the dacha, to your private house. But the supply in such towns is always unstable. This is where the reservoir comes into play.

Important ! The storage tank can hold a large number of water and maintain a stable pressure 24 hours a day.

The very principle of operation of the storage tank in the water supply system of a private house is interesting. You do not need to turn on anything or be afraid that there will be no water in the kitchen due to the fact that the device will take it all. The tank is very well thought out. It stores water little by little, creating a reserve stock for critical situations.

What are the water supply systems of private houses with storage tanks

Tank at the top

In this scheme of water supply of a private house, the storage tank is mounted on the second or third floor. You can also install a tank in the attic. The principle of operation is the same as that of a water tower.

When installing a storage tank at the top in the water supply system of a private house, water will flow through the pipes by gravity. This, in turn, will save you a lot of electricity and save you money on long utility bills.

Important ! This tank is extremely easy to maintain.

Separately, we need to talk about the power of pressure. Despite the fact that the water flows by gravity, the pressure cannot be called particularly strong. More precisely, it directly depends on the height at which the tank is located.

For example, if the tank is located at a height of about 10 meters, the pressure will be 1 atm. For ease of calculation, let's take a three-story house. The height of each floor, let it be, is three meters. When installing a tank on the roof of the third floor, the pressure on the first floor will be exactly one atmosphere.

The main disadvantage of this system is that with each floor the pressure will be lower and lower. And below. As a result, on the second floor it will be about 0.6 atm, and even less on the third. Although if you are going to install taps only on the first one, this is more than enough.

Important ! The tank takes up useful space.

Very often, the attic in the country is used to store dear to my heart things that simply do not raise a hand to throw away. Besides modern technologies allow you to make an excellent room from the attic floor with all amenities. True, this will require insulation and waterproofing, but the result is worth it.

Advice ! If you have plans for the attic, then don't give up on them for a tank with an overhead position. Just take it outside the house to the flyover.

Bottom location

If you want to make the most of all the space available inside a private house, you will need just such a water supply system. Moreover, even from the outside, the container will not take up an inch of the ground.

Tell me it's impossible? In fact, everything is quite simple. The reservoir is buried in the ground and from here the water supply of a private house is realized. The container does not need to be buried deep. Half a meter will be enough.

On top of the tank, you can safely grow flowers. The water supply system of a private house dug into the ground will not harm them in any way. There is no limit on the capacity of the container. But you must remember that a large volume is recruited longer, and, accordingly, water intake in especially hot summer days may become critical.

Important ! When choosing a container, you need to take into account the thickness of the water reservoir and its capabilities, as well as the needs of your subsidiary household.

Unfortunately, the lower location of the water supply system of a private house has its drawbacks. The most significant is the need to purchase a pumping station, which means additional electricity costs in the future.

Underground tanks in the water supply systems of private houses are made of special materials which are able to withstand increased moisture and even freezing. Nevertheless, breakdowns sometimes happen, and then it is extremely difficult to restore the system. After all, the reservoir is buried underground.

Important ! In order for the water tank to serve you for a long time, the soil must be insulated. This will prevent the effect of frost on the structure.

Putting the tank in the ground

The installation of a water supply tank for a private house begins with the selection of a suitable place for installing the product. It is desirable that the design of the container has a round shape. Pay special attention to the stiffening ribs, without them it will not be possible to properly install the device.

If you buy a storage tank of some other shape and without ribs. About him correct installation will have to take extra care. This will require a concrete shell. It is she who will ensure reliable fixation in the ground.

There should be a special hole in the upper part of the structure. It is best done in the form of a hatch. It is necessary in order to carry out an audit from time to time, viewing the state of the storage tank of the water supply system of a private house from the inside.

Important ! The storage tank must be installed with an inclination of no more than 15 degrees. This will make cleaning much easier, since precipitation will accumulate just under the hatch.

Installing and connecting the storage tank

A float valve must be installed on the inlet pipe of the storage tank for a private house. You also need to think about an overflow pipe in case the float valve breaks. It will insure the system from overflowing with liquid.

Important ! Provided that the water is taken from your own source, by means of a pump, take care of the float switch.

A filter must be installed at the inlet to the storage tank for a private building. They are of three types:

• centrifugal,
• cyclone,
• mesh.

Perhaps, the best option for the storage tank of a private house is precisely the strainer. Its price is relatively low, and its efficiency is more than enough to purify not particularly polluted water. The remaining two types are needed when the liquid has high level pollution.

It is best to fill the tank through a diffuser. This precaution will prevent sediment from rising and entering the water supply. A pipe cuts into the storage structure from above. It will act as ventilation.

Important ! The pipe opening should be directed downwards, while a special mesh must be fixed to prevent debris from entering the system.

The main role in connecting the water supply system of a private house with a storage tank is played by a pump. It is he who is responsible for the delivery of water to the final consumer.

Important ! The suction line must have a non-return valve. It is installed on the pipeline leading to the house.

Of course, when connecting, one cannot do without such important elements water supply systems of a private house with a storage tank, such as:

• water level sensor,
• float switch,
• protection relay.

All these elements in the water supply system of a private house must be perfectly combined with each other, and then everything will work perfectly.

The pump is connected to the pipeline by means of a reinforced hose. Often outside diameter pipe is 32 mm, but exceptions are possible. The pipeline goes to the reservoir.

In some cases, in private homes, storage tanks are installed between floors. In such cases, you need flooring from strong boards. This will allow you to distribute the load as evenly as possible.

We connect the expansion tank

The expansion tank is slightly different from the storage tank. It is also called a hydraulic accumulator. The role of this device is to compensate for the pressure inside the system.

Important ! A volume change membrane is installed in the tank itself, which ensures the normal operation of the water supply. A similar device is installed in heating systems.

If the expansion tank for the water supply system of a private house is open, it is installed at the very top. closed type structures must be installed in front of the circulation pump. This is the most suitable place.

When connected, the coolant is supplied from above. Also, the system must have a pressure gauge and safety valve. Without this, the heat supply in a private house will not be able to function normally.

Results

It is difficult to overestimate the importance of storage tanks for water supply systems of private houses. They allow you not to depend on the stability of the water supply. all year round. In addition, due to the simplicity of the design, they are easy to install.

Expansion tanks for private houses additionally perform the functions of protection against water hammer and are most often used in heating systems. The best solution for a private house is a membrane type of device.

One of the most annoying household problems is the lack of water in the tap. It is easy to survive the absence of light or gas, but water is an indispensable component of human life, and when it is not there or not enough, problems begin. You can constantly keep several containers of water in the house, for example, plastic bottles, but it is much more practical to determine what kind of storage tank for water supply and the system diagram for a private house are needed so as not to lose comfort and continue to use household appliances and a sink with a bathroom, no matter how what never happened.

Why is it needed and how to use it

If for some reason the pump in the autonomous water supply system does not work, or there is no pressure in the centralized city water supply, then it can be supplied to the sink or toilet bowl from a previously collected reserve tank. In other words, it is better to always have a supply in the house. drinking water and use it in emergency situations.

For the convenience of using the reserve water supply, the storage tank must be integrated into the water supply system so that it is either automatically used in the absence of external pressure, or it can be activated by simply turning the valve.

There are many variations on how to install and connect a storage tank, depending on the type of water source, the possible location of the tank, and even the layout of the house. Enough to choose suitable option and decide on the type of storage tank itself.

Types

The storage tank can be a tank with a sufficient internal volume, made of a material resistant to corrosion and safe for storing drinking water. The following materials are used:

• polyvinyl chloride;
• cross-linked polyethylene of high or low pressure;
• polypropylene;
• stainless steel;
• steel coated with waterproof varnishes and ceramic coatings.

plastic tanks

Although galvanized steel is resistant to corrosion and waterproof, over time the protective layer of zinc can become thinner, especially at the joints and welds.

By design, allocate:

• open containers that have a neck with or without a lid, but with sealed walls and a bottom;
• closed fully sealed containers of membrane type.

In the first case, everything is simple, the entire internal volume is filled with water and, if necessary, drains through a pipe fixed at the lowest point.

In the case of membrane storage tanks, the usable volume is at least a third less than the volume of the entire structure. Part of the volume is allocated under the air chamber, separated from the water by a strong elastic membrane. As the container fills with water, the membrane presses on the air chamber, creating excess pressure. When it is required to receive water back, the valve opens, and it enters the water supply system under the action of the accumulated pressure.

Bottom or top

There are three options for connecting the storage tank and using the water supply:

• Top location of the container. In this case, the water intake is carried out under the action of gravity. The higher the accumulator is located in relation to the consumer, the stronger the water pressure. Every 10 meters of altitude adds 0.1 atmosphere, or about 1 bar.
• The lower location of a simple storage tank. Gravity will no longer help, and a pump is used to supply the water supply, raising the pressure to the optimum level.
• Membrane-type storage tanks themselves create the required pressure for water supply. The lower location at the level of the consumer is optimal for them, since there will be no advantage from installation in an attic or tower.

How to determine the best option?

If the house has several floors and it is possible to place the storage tank in the attic, then this will allow you to do without additional installation of the pump, and you do not need to spend money on an expensive membrane tank. In fact, this is an analogue of a water tower. However, raise the container so high as to provide a comfortable pressure at the level of 2-2.5 atm. it's still difficult. Moreover, the question arises of warming the tank so that in winter the water in it does not freeze.

In the event of an emergency shutdown of the available water pressure of 0.2-0.3 atm. will be quite enough to use the faucet in the sink, toilet or even shower, but it will not be possible to use part household appliances such as a washing machine or dishwasher that requires more pressure to operate the solenoid valves.

Installing the tank at the level with the consumer is suitable in cases where it is not possible to raise the tank to the attic or at least one floor higher. The same applies to the installation of a storage tank in the apartment. You will need a small pump to supply water to the water supply under pressure. To ensure adequate operation, the pump will require an expansion membrane tank.

A storage tank with a membrane is perfect for storing water both when using a centralized water supply system and in autonomous system. However, it does not require additional equipment or top location. However, its cost is much higher than any conventional storage tank, even when combined with a simple pump.

Volume of the tank

In the event of problems on the city water line and water cuts, it is usually repair work done in a day or two. However, accidents also happen on holidays and in places where quick repair simply impossible, then you have to wait much longer. The optimal supply of water for 2-3 days is based on the use of the toilet, maintaining personal hygiene and cooking.

For a family of three, 100 liters per day is enough when using water in economy mode. For one wash, approximately 80 liters of water are required, more precisely you can find out in the passport to washing machine. Same for dishwasher.

It turns out that for 2-3 days when using household appliances, you need to look for a storage capacity of at least 500 liters, half a cubic meter.

However, there are a number of limitations:

• The larger the volume of water and the storage tank of an open type, the faster it will begin to overgrow with sediment. It is not recommended to use containers with a volume of more than 200-250 liters in everyday life for long-term storage of water.
• The margin of safety of the ceiling and load-bearing walls should be taken into account. The installation of the tank must be laid at the design stage of the house.
• When using autonomous water supply, the volume of the storage tank, especially of the membrane type, should not exceed the debit of the well. If this rule cannot be observed, then the pump must be protected from idling.

Membrane-type storage tanks are limited in their volume and are not able to give up the entire supply of stored liquid. To form a stock of more than 300 liters, you will have to connect several tanks of a smaller capacity in parallel to each other.

General connection rules

A water tank is installed on a prepared site: concrete base tied with a foundation, or a reinforced metal frame made of profiled pipes. The design must withstand one and a half weight of the tank and the water in it when completely filled.

The inlet pipe can be of any suitable diameter, water is supplied under pressure. The outlet pipe and the pipe to the water supply are chosen with a diameter one and a half to two times larger than the cross section of the main line. Optimal size 32 mm.

Insulation, even of the highest quality, only slows down the decrease in temperature in the tank. To prevent freezing of water when installing the tank in an unheated attic or on the roof, any suitable heating system for pipes and the tank itself should be used.

With centralized water supply

Any type of storage tank connection requires check valve at the entrance to a house or apartment. It is the valve that will prevent the flow of stored water back into the pipeline, and not to the consumer.

Top connection

The tank is installed under the ceiling of the first floor, the floor above the bathroom and kitchen or in the attic. The tank should have a fitting at the top for water supply, another one a little higher for discharge into the sewer when overflowing, and a fitting at the very bottom for water intake.

After entering the coarse filter of the shut-off valve, the meter and the check valve, a tee is installed, from which the pipe goes to the tank inlet, a shut-off valve or a controlled valve is installed in front of the fitting.

A shut-off valve is connected to the outlet fitting and the pipe is lowered back to the water supply, to which it is connected by means of a tee.

The excess discharge hose is lowered into the sewer or led out of the house into the front garden or drainage system.

To control the filling, a mechanical valve with a float is used, similar to those used in the toilet bowl.

To use the stored water, it is enough to open the outlet valve.

Bottom connection

Connection is identical to the first option. However, a pump must be installed at the outlet to create additional pressure in the water supply. Before each use of water, you will have to turn on the pump first.

Ready to help simplify life pumping station or pump add-on expansion tank membrane type and pressure switch.

Bottom connection of storage tank with membrane

To connect the tank, only one pipe is used, connected to the water supply through a tee with a valve. The insert is also carried out after the filter, counter and check valve.

Before use, the pressure in the air chamber must be adjusted. This must be done strictly in accordance with the instructions for the selected model. The normal pressure in the water supply is preliminarily studied, moreover, taking into account fluctuations during the day. As a result, the average value is taken, which is used to adjust the tank. This is the only way to use the maximum useful volume of the tank.

For autonomous water supply

As in the case of centralized water supply, there are several connection options.

Water tower

The storage tank is installed at a level of 15-20 meters above ground level on a reinforced tower or attic. Water from well pump or pumping station is fed directly into the tank, and from there it is distributed to the bathroom and the kitchen in the house. The pressure in the system is provided by the height difference between the water level in the tank and the mixer tap in the house.

The disadvantage is the constant passage through the water tank, which will cause sediment to accumulate over time, even if a filter system is pre-installed.

The advantage is the simplicity of the design and the minimum of expensive elements, with the exception of the tower structure itself and the obligatory insulation of the tank to protect it from freezing even when it is placed in the attic.

Bottom tank connection

The tank is installed flush with the pumping station or on the ground floor in the house. It is filled during normal operation of the pump due to water from the well. The limiter is a float switch.

This option saves with excessive water consumption and a decrease in the water level in a well or well. However, it is useless when the electricity is turned off, since a pump is required to supply the end user with water from the reserve.

Membrane storage tank

A membrane tank for storing water is installed after the pumping station and the check valve, with a bottom connection. If the pumping station for some reason does not work and does not maintain pressure in the system, then water comes from the storage tank.

Everything ingenious is simple! Even in the 21st century, where technical achievements are sometimes incredibly difficult to understand, there is a place for simple and ingenious inventions. One of them is a storage tank for water.

What is a storage tank and do you need one?

The storage tank is a simple, but very useful device, almost indispensable in the conditions of autonomous water supply. Even calling it a device seems wrong, because it is an ordinary container into which water is supplied from a well or well, and from where it subsequently enters a boiler or pipes.

It is difficult for city dwellers to understand what problems an illiterate arrangement of an autonomous water supply system in a private house can turn into. They live in an apartment that was originally supplied with water, they have hot shower, the opportunity to take a bath at any time, wash the dishes, start the washing machine, not to mention the water heating - the designers, builders and utilities took care of everything. The source of water supply for a city dweller is the most reliable, and all problems with interruptions in the flow of water are not solved by him.

However, those who live in cottage and holiday villages know how difficult it is to organize a reliable and affordable source of water, to which you can connect a pumping station and get the necessary water pressure. Most often the conditions country house not so perfect, for example:

• The house has a connection to a centralized water supply, however, water is supplied here not around the clock, but several times a week (this is typical for many summer cottages);
• There is a well on the site, but its productivity is not too high - it quickly empties and it takes time to fill up;
• Water comes from an artesian well, which is almost impossible to drain, however, only an automatic pump can be used to supply water, which is turned off in case of network outages.

The storage tank acts as an accumulator, storing water during the period when there is no need to supply it to the house.

Private water supply system with storage tank

There are two types of water supply systems of a private house with the participation of a storage tank - with an upper and lower tank. As the name implies, the fundamental difference here lies in the location of the tank relative to the water supply.

Water supply with top tank

The storage tank in such a system is located on the top floor of the house. It works on the principle of a water tower. The advantage of this option will be, first of all, the possibility of autonomous operation of the equipment. Water will flow to the water intake points in a natural way, without the use of a pump. However, one should not expect a strong pressure - as we remember, the height difference between the water source and the tap, equal to 10 m, creates a pressure of 1 atm. If we apply this to real conditions and assume that the tank will be installed in the attic two-story house with a ceiling height of 3 meters, the pressure in the taps on the first floor will be only 0.6 atm, and on the second floor - half as much. At the same time, we do not take into account the hydraulic resistance of the pipeline.

Due to the low pressure of water coming from the upper tank, such a system is recommended for use in country houses where the need for comfortable water supply is minimal. Permanent residence in the house will require a more modern approach

In addition, a fairly large tank installed indoors will take up useful space. As a summer option, you can install a tank on the street on a special overpass, but this option is not suitable for winter. However, there is a way out here too - electric heating of the tank and insulation of the pipeline. Calculate how much this venture will cost you ... No, definitely worth looking for more rational decision! And, fortunately, it has been around for a long time.

Water supply with bottom tank

The lower tank is a solution for those who strive for comfort and know how to properly use the space of the site and at home. The tank is buried in the ground here. And even this plot of land you can use - by digging a tank half a meter below ground level, you get a site suitable for growing flowers or plants that are not related to root crops. The dimensions of the tank in this case are not limited by anything, and the larger it is, the longer it can cover the difference between the needs of the inhabitants of the house in water and the available resources.

Of course, there are cons, but they have a completely familiar form:

• You will need a pumping station to extract water from the tank and supply it to the house;
• By placing the tank underground, you make cleaning and repair difficult to access - to make the task easier, make holes for revision and cleaning, and position the tank itself slightly at an angle so that the sediment masses accumulate in one place (preferably under the cleaning hole);
• In winter, without insulation, the tank can freeze, and in the spring, if it is not positioned correctly, it will lead.

A plastic tank buried in the ground should have either a round shape or stiffeners, if both options are not available, create a concrete shell around it

How to calculate the volume of the storage tank?

Two quantities are involved in calculating the required volume of the storage tank:

• Water consumption. The average data will be here a very average value to start from it. Consumption depends on the set of possibilities for using water in the house and the number of inhabitants. Your home may only have a couple of sinks and a toilet, or it may also have Dishwasher, shower cabin, washing machine etc. Of course, the difference between the two options will be great. In general, the consumption per person per day is about 200 liters of water in the presence of all the benefits of civilization. In conditions country house where water is used for cooking and washing dishes, this consumption is reduced to about 60 liters per day. However, it is best to calculate your expenses yourself;

• Frequency of use. Measure your needs and the possibilities of your plumbing. You can choose a huge tank that will hold water for all your needs, but if the capacity of the system is not enough to pump enough water into it in the allotted time, the need for a large tank simply disappears. In addition, it is worth considering the reasons why you decided to purchase a storage tank - if it serves to insure against rare and short-term power outages (when powered from a well) or water (when supplied from a centralized water supply), a small tank will be enough for you.

Do not confuse a storage tank with a hydraulic accumulator, which serves to get rid of frequent short-term switching on of an automatic pump - it stores 25-100 liters of water and is used to conserve pump resources and extend its service life

What is the storage tank made of?

Accumulative tanks are made of food stainless steel or food plastic. In production, they strictly monitor the quality of the material, because water will be in contact with it for quite a long time, which will subsequently be used for food purposes.

Design features are:

• Float valve mounted on the inlet pipe. If the house uses autonomous water supply, the tap is replaced with a pump float switch. For a warning emergency situation in case of breakage of the float, an overflow pipe cuts below the inlet, it joins the sewer;
• A filter is also installed at the inlet, which is selected depending on the degree of water contamination - for relative pure water mud collectors are chosen, and for water with a large amount of sediment - cyclones or centrifugal pumps;
• Also, a strainer is installed on the outlet pipe or right before wiring to the house;
• If the tank has opaque walls, it is worth embedding a level into it;
• Underground tanks are equipped with hatches for cleaning, and the upper tanks - drainage pipe, embedded at the bottom;
• It is better to use a diffuser to fill the tank with water - this will prevent mixing and agitation of the sediment;
• At the top of the container should be placed ventilation pipe bent at an angle to the ground. When the water is drained and there is no air access, the tank is deformed.

So, you have already made sure that the storage tank is indispensable for a private house. Whatever it is, one thing is clear - it definitely should be.
