Replacing pipes in the bathroom and toilet with polypropylene prices:
Replace the pipes in the apartment (bath, toilet and kitchen) with polypropylene pipes at a fixed price. The cost depends on the number of connected plumbing fixtures in your apartment. Prices for replacing pipes are indicated without wall gating with a serial connection scheme.
one plumbing fixture is, for example, a toilet bowl,
if in your case, when replacing pipes, you need to connect: a toilet bowl, a bathtub and a sink - then these are 3 connection devices.
The purchase and delivery of materials is free of charge.
The customer can purchase the material himself.
Installation of water meters - free of charge.
Water meters are not included in the cost of materials.
We use only high quality polypropylene pipes.

Mounting on the walls is carried out using special holders - latches that fix both pipes (hot and cold) side by side. Fasteners must be carried out every 50 cm to avoid deflection of pipes under their own weight.
Also, when installing polypropylene pipes, it is necessary to take into account a sufficiently large thermal expansion of plastic, therefore, when embedded in walls, it is recommended to use the "pipe-in-pipe" or " pipe-in plastic sleeve" so that there is a small gap that allows the pipe to expand in the wall under the influence of temperature changes.
The pipes are made from polymer materials, they are not subject to any kind of corrosion,
neither electrical nor chemical, respectively, do not overgrow with deposits from the inside, do not conduct stray currents.
Polypropylene pipes have a long service life - about 50 years. The low thermal conductivity of the pipe material makes it possible not to use thermal insulation. To connect to metal communications, plastic fittings with built-in threads are used. There are also plastic taps (metal inside, plastic outside).
There is nothing eternal! And if there is, it may cease to suit. So it is with communications. The owners sometimes have a desire to update the network in whole or in part. There can be a lot of reasons for this - from an elementary leak to a change in design.
Let's figure out how to replace pipes with plastic ones with your own hands.
Plastic is the most sought after material today.
Introduction to plastic pipes
What are the advantages of the material and are there any disadvantages? How to make sure that the optimal choice is made? About everything in order.
Advantages and disadvantages
Why replacement metal pipes on plastic - a wise decision? The secret is in the special properties of this material.
Among the advantages are:
- service life (up to 100 years, depending on the type of structure);
- lightness of the material;
- resistance to corrosion;
- ease of installation;
- strength;
- noiselessness during network operation;
- elasticity;
- environmental friendliness (the chemical composition of the liquid moving through the system does not change);
- low thermal conductivity;
- versatility of the gasket (the material can be mounted both open and in a closed way);
- ease of transportation;
- moderation in price.
Pluses - a lot. Plastic is the most optimal material among its "brothers". Networks from it serve for a long time and do not cause trouble for the owners, of course, if the replacement of plastic pipes in the apartment was done correctly.
There are few disadvantages - just a few:
- restrictions on the temperature of transported substances (depending on the type of structure);
- selection of installation technology (they also vary and depend on the type of material);
- compatibility in composition (control that liquids that can corrode plastic are not transported through the network).

Types of plastic structures
Let's consider how to replace the old ones with plastic pipes so that the minuses do not appear. In the process of manufacturing products, other substances are added to plastic, so you can find the following markings on purchased items:
- MP - metal-plastic. It is said that this "duo" of components is ideal for honing home skills. The material does not fail either in the cold (it withstands frost very well), or when transporting liquids with high temperatures (up to 900 degrees). The only negative is the sensitivity to external deformation. Bend such elements carefully.
- PE or polyethylene. The main advantage of such a composition is that you can work with it even at low temperatures, that is, even when it is -20˚ outside the window, you can carry out work on laying a network of polyethylene or repair already installed communications. The main thing is to choose the right pressure threshold - low or high.
- PES, which means cross-linked polyethylene. Such material is used both for laying water supply lines and for heating networks. Why "stitched"? It's just that the pressure treatment technology that aims to increase the resistance threshold to temperature changes and increase stability is called "crosslinking". Elements are treated with nitrogen, silane gas, peroxide method or electron beam irradiation.
It looks like cross-linked polyethylene
- PVC or polyvinyl chloride. If you see such a marking, do not buy the product if you plan to install a network for domestic use, since chloride is present in the composition. Such material is suitable for arranging swimming pools, chemical plants, but not for the home.
- PP - polypropylene. This material is suitable for bringing water to housing. Thanks to a special device (3 layers - protective, plastic itself and foil), the products are resistant to temperature changes, they can successfully transport liquids that reach temperatures of more than 1000 degrees. However, there are also disadvantages: low elasticity (products do not bend well), the impossibility of replacing elements (welding is used “forever”, therefore replacing a damaged section of a plastic pipe is impossible in this case).
And this is polypropylene.
Replacement Technology
It's time to move on to practice. Consider how the replacement of metal-plastic pipes takes place.
Due to its lightness and plasticity, it is a pleasure to mount plastic
Work order
Planning everything right is half the battle. Preparatory stage no less important than repair work. If you have decided on the material, then proceed according to the following scenario:
- Draw a plan or a drawing of what exactly you are changing and how you are going to do it.
- Calculate how much material is required for the work.
- Purchase pipes and fittings.
- Find tools and devices for connecting products.
- Turn off the water.
- Dismantle the old network fragment.
- Install plastic parts.
- Check system performance.
- Get rid of trash.
- Enjoy the result.

Dismantling of old elements
Do-it-yourself replacement of pipes with metal-plastic pipes begins with destruction. Dismantling can differ only in technology and the number of tools involved. Breaking is not building, so you can figure out how to remove failed network fragments yourself. Somewhere it’s really possible to unscrew it, and in other places you will have to use a grinder to cut it off.
For work, get the following tools:
- hammer with a wooden or rubber nozzle;
- Bulgarian;
- perforator;
- chisel;
- grinding discs;
- screwdrivers;
- wrenches.
Worth paying attention! Try to combine pipe replacement and repair, then you can hide the new network in the walls.
This is what the wall looks like after changing steel to plastic
Plastic installation
Once the old items are unmounted, you have two options:
- install new ones in their place - plastic fragments;
- lay the network differently - according to the new plan.
The connection of plastic products depends on their complete composition. Construction solder/welder or chemist welding techniques can be applied, either with fittings or gaskets and bolts. Focus on the type of plastic pipes you prefer.
If you want to "drown" the network in the walls, you will have to make strobes before installation. Do not forget about the insulation of the elements. Turn on the water only when the products turn into a complete system.

Replacing iron pipes with plastic pipes is one of the most popular services among homeowners today. Plastic pipes themselves have an optimal price-quality ratio and are rapidly replacing steel and cast iron pipes. It is more convenient to find a master for replacing water supply pipes in Moscow and St. Petersburg through the Youdo.com mobile platform.
Replacing pipes with plastic ones
Today it is much more profitable to entrust our performers with plumbing work for a number of reasons:
- the customer himself sets the price for the work
- create tasks from anywhere
- polite and friendly attitude of the performers
- quality assurance and deadlines
Replacing metal pipes with plastic ones is justified both from an economic and environmental point of view.
Advantages of plastic pipes
- high anti-corrosion performance
- safe home use
- quietness of the pipeline
- low thermal conductivity
In order to replace pipes with plastic ones exactly according to the instructions, our performers weld the pipes with special tools. The main thing is that the heating temperature is clearly maintained, which is different for each pipe diameter. At the request of the customer, plastic pipes can be hidden in the walls. This gives an aesthetic look to the room.
Scheme for the installation of plastic pipes
The price of replacing pipes with plastic ones from our performers is the most favorable throughout the region. Usually, pipes in houses are changed once and for a long time. No need to replace the pipeline in the house separately. It is better to do all the work at once. Replacement of plastic pipes is carried out according to the following scheme:
- measurements are made to determine the length of the network
- components and locations of devices are determined
- the required number of tees, corners and other details is calculated
- turning off the water supply in the house
- dismantling of old and installation of new pipes
It would seem that there is nothing complicated. But, as practice shows, in the course of work, situations arise when a prompt solution to the problem is necessary. Our performers have an impressive list of works and numerous reviews from grateful customers.
