Replacement of water pipes in a private house. Quick replacement of water pipes
Repairing or replacing a water supply system is one of the most serious and difficult tasks, since the lack of water causes a lot of difficulties.
The following signs indicate a breakdown in the water supply system:
- noticeable decrease in water pressure;
- When you turn on the water, you hear an uncharacteristic noise;
- Rust particles and other elements were found in the water.
Noise in pipes occurs when water leaks, caused by the formation of a plug or fistula. In addition, noise in the pipes can be heard when the plumbing breaks down or there is a water leak in the neighbors’ apartment, and whistling from the pipes indicates a narrowing of the clearance.
The need for pipe diagnostics arises in the case of prolonged use of the water supply system, constant noise, low pressure and contamination.
Experts conduct an inspection to identify the causes of emerging problems using one of three technologies:
- Use of safe chemicals.
- Pulse water hammer.
- Hydrodynamic flushing.
Repair and replacement of cold and hot water supply systems in Moscow: reasons and tips
Often this procedure is required due to pipe corrosion. One of the common methods of repairing a pipeline is to install a clamp with a rubber seal on the leaking area, and in the case of a water supply system being out of service, replacing the pipes. Our company recommends purchasing plastic pipes, known for their durability and ease of installation and use.
Installation of plastic pipes requires the presence of ball valves, a filter system, meters, fittings and adapters. During installation, the system is connected to the riser through a ball valve, then the filter, meters and, ultimately, the water supply.
The most rational approach would be to install polyethylene pipes, which can be purchased from our company at an affordable price. Such pipes are famous for their strength and reliability, and are environmentally friendly.
The only caveat is that HDPE pipes will not replace hot water supply pipes, since they are destroyed under the influence of high temperatures. Hot water pipes are replaced with heat-resistant ones made of cross-linked polyethylene. The guaranteed service life of such pipes is 50 years.
Repair and replacement of the water supply system, the price of which today depends on the volume of work, is carried out by any plumbing service.
The pipe replacement process consists of the following steps:
- Dismantling of the previous water supply system.
- Marking and fastening of pipes.
- Fastening pipes with fittings.
- Diagnostics of pipes, water supply.
Cost of services for replacement and repair of water pipes
Hydrodynamic flushing of pipes, which is one of the most common services, will cost clients approximately 3,000 rubles, and cutting into the water supply system will cost from 1,300 rubles. Repair and replacement of the water supply system, pumps, risers, pipes in the country, for example, will be done at a price based on the severity of the problem.
The cost of repairing and replacing the water supply system in a private home will depend on the amount of work performed and the previous installation system. As a rule, specialists charge 250 rubles per linear meter for installing a pipeline. A linear meter is cheaper when dismantling old pipes.
The price for a groove in a concrete or brick wall is set taking into account the diameter and ranges from 200 to 1200 rubles. For the installation of shut-off valves you will need to prepare about 200 rubles per unit, and replacing water supply pipes will cost around 500 rubles. A linear meter of PDN can be purchased for 125 rubles. Polypropylene pipes and Rehau pipes will cost a little more.
Do you want to provide water supply to your country house on your own? Agree that doing this work with your own hands is a completely feasible task if you know the nuances of constructing a water supply system.
We will help you understand the intricacies and basic rules - in this article we will talk about how to install a water supply system in a private house with your own hands. Where to start and how to carry out all the work correctly.
For a better understanding of the process, we have selected visual photos and plumbing diagrams. The article is also supplemented with useful video recommendations on the rules for installing water supply and tips on installing system input nodes in a country house.
Regardless of whether the water supply is installed in an existing building or installed during the construction of a new one, its design and installation must be approached very responsibly.
First of all, you need to decide on a source for water supply. You need to know that according to the standards, the water supply system must provide water to each person living in the house based on the calculation of 30-50 liters per day per person.
When arranging a bathroom and sewerage system, the calculated figure increases three times. For watering the garden and green spaces, a water consumption of at least 5 liters per square meter is assumed. meter.

It turns out that the volumes of water consumption of a country house are quite large. Therefore, the choice of water source must be approached as responsibly as possible.
The owner can choose between decentralized and centralized water supply. In the first option, the source of water supply will be, etc. In the second there is a water supply network that supplies its settlement.
Collector diagram for water supply distribution
The main difference from parallel wiring is the presence of a special distribution unit - a collector, from which a separate pipeline is laid to each consumer. This makes it possible to supply water to all water points with the same pressure.
Depending on the length of the system, it may include several collectors. The main disadvantage of such a system is the high consumption of pipes.
A typical water supply diagram looks something like this. It starts either from the point of insertion into the centralized main line, or from the area where the system is connected to a well or other source of water supply.
In the latter case, a pump or pumping station must be installed here to supply water to the system. It also assumes the presence of a hydraulic accumulator and a shut-off valve, which is used in the event of a leak or scheduled repairs.
If necessary, divide the water flow, use a tee. It will generate two streams: one will be used for technical needs, such as watering the garden, swimming pool, shower, etc., and the second will be sent to the house.
The pipe that carries water into the house must be equipped with a filtration system to clean the liquid from all kinds of impurities.
At this stage, coarse filters will be quite sufficient.
The collector is a distribution node in which the total flow is divided into several branches
Next, you will need to install another tee on the pipe entering the house. This is done only if it is planned to organize hot water supply. The flow will be divided into cold water and water sent for heating.
The cold water supply pipe is connected to the corresponding collector, from which distribution is carried out further throughout the building. The hot pipeline is first connected to the water heater, then to the corresponding collector, and then in the same way as the first option.
When designing wiring, experts strongly recommend reducing the length of pipelines as much as possible and keeping the number of joints and bends to a minimum. After all, they are the potential causes of leaks.
In addition, it is highly undesirable to turn pipes at right angles. This significantly reduces the pressure in the main line.

The water supply can be laid in a hidden or open way. The first is the most aesthetic. He assumes that the pipes will be laid in grooves laid inside the walls or covered with decorative boxes.
In this case, it is important that the material from which the parts are made is not susceptible to corrosion, since it will be extremely difficult to notice a leak in time. Open-mounted pipes are laid on top of the walls.
Stages of plumbing installation
When installing water pipes in a private home yourself, experts recommend following several rules and adhering to a specific plan of action. Let's talk about this in more detail.
Stage #1. Preparing for work
First of all, it is better to start laying the pipeline from the water consumer, and not vice versa. It will be easier. First, using an adapter for a threaded type connection, we attach the water pipe to the consumer.
It is advisable to install a shut-off ball valve between the adapter and the device. It will make it possible, if necessary, to quickly shut off the water supply or repair a broken device without any problems. The pipe is led from the water consumer to the collector.
Also, when doing wiring you need to follow a few simple rules:
- The pipes should be placed at a distance of about 20 mm from the wall, this will make them easier to repair.
- It is highly undesirable to lay pipes so that they pass through partitions or walls. If this is still necessary, the parts are placed in a special glass.
- Clips are used for fastening to walls. They must be present every one and a half to two meters and at all corner joints.
- If drain taps are to be installed, the pipe is laid with a slight slope towards it.
- When going around an internal corner, the part is placed at a distance of 30-40 mm from the wall, when going around an external corner - 15 mm.
Before connecting to the collector, it is strongly recommended to install shut-off valves on the pipe going to the consumer. This will allow you to quickly disconnect the branch from the system in the event of an emergency, as well as repair it without unnecessary problems.
Water pipes can be laid in a hidden way inside grooves made in the wall of the building. The hidden installation method is most often used to implement collector wiring
Stage #2. Pipe selection
The parts from which the plumbing system is assembled must be inert to chemical and temperature influences, durable, wear-resistant and as light as possible.
That is why polyethylene, polypropylene or polyvinyl chloride pipes are most often chosen to install a system in a country house. When choosing, you need to take into account the operating temperature of plastics; not all can interact with hot water.
Modern plastic parts are equipped with a large number of components, which allows you to assemble a structure of any degree of complexity.
Alternatively you can use . There are many arguments in favor of assembling a water supply system from plastic elements. First of all, the design is lightweight, but at the same time durable.
Installation of the system is so simple that even a beginner can handle it. Soldering is used to fasten parts together, resulting in very strong, almost monolithic joints.
Another plus is the ability to bend elements, which can significantly reduce the number of dangerous areas in an emergency sense. Where it is necessary to connect metal and plastic elements, special combined type fittings with special metal inserts are used.
Plastic parts have high torsional rigidity. This is very important for cases where the pump develops high torque.
If necessary, the plastic pipeline can be modernized, which is also important. In addition to plastic and metal-plastic, you can use traditional options. These include parts or.
The main disadvantage of the first option is the susceptibility to corrosion. Copper pipes have many advantages, but their cost is very high.
An important point is the choice of the diameter of the parts. It is carried out based on the length of a specific pipeline section.
For lines longer than 30 m, parts with a diameter of 32 mm are selected; pipelines shorter than 10 m are assembled from elements with a cross-section of 20 mm. Medium-length lines are mounted from pipes with a diameter of 25 mm.

Stage #3. Connecting the pumping station
Another important issue that must be considered when installing water supply in a country house is.
It was already mentioned above that a pumping station or pressure tank can be used to provide the building with a sufficient amount of water. Using the second option is quite troublesome. As practice shows, most homeowners choose a pumping station.
The device pumps water from a well, or less often from a well. This equipment is sensitive to low temperatures, so it is placed in the basement, basement or heated technical room.
True, in this case, the noise from the operating pump may disturb residents. In some cases, the equipment is placed in a specially equipped caisson that covers.
A pumping station is a set of equipment that ensures complete pumping of water from a well or a well.
Work on connecting the pumping station is generally carried out as follows. A pipe is connected from the source to the equipment, onto which a brass fitting equipped with an adapter with a diameter of 32 mm is put on.
A tee equipped with a drain valve is connected to it. This will make it possible to turn off the water supply if necessary. A check valve is connected to the tee. The device will not allow water to return to the well.
It may be necessary to turn the line to direct the pipe to the pumping station. If this is the case, a special corner is used. All subsequent elements are connected using the so-called “American”.
First, a shut-off ball valve is connected, turning off the water supply if necessary. Then a coarse filter is installed, which will protect the device from impurities.
The pumping station can be installed in an insulated caisson above the well head, or can be installed in a house, in any heated room
After this, the pumping station is connected. There is a nuance here. The equipment involves the installation of a damper tank and. If the pump is located in the well and all other equipment is located in the house, then the pressure switch is installed on top of the pipe.
A damper tank is mounted below. After this, the dry running sensor is connected. It will not allow the pump to work without water and will protect it from damage.
The last connection element is an adapter for a pipe with a diameter of 25 mm. After all the parts have been installed, it is recommended to check the quality of the work performed. To do this, start the pump and let it run for a while.
If the equipment pumps water properly, then everything is fine and work can continue. If not, you need to find the cause and eliminate it.
Stage #4. Installing a hydraulic accumulator
Stage #5. Installation of water purification equipment
Water treatment is also not a mandatory element of the water supply system. However, practice shows that most homeowners install such equipment. It is especially necessary for those who use a borehole or well as a source of water.
The quality of such water is usually far from ideal. The liquid coming from the well is in most cases contaminated with mechanical impurities.
Therefore, at a minimum, it is worth installing coarse filters. To fully protect the water supply system and the household appliances connected to it, you should accurately determine the nature of the impurities and the chemical composition of the water coming from the well.
To do this, the samples are taken to the laboratory and obtained, which will show which filters are needed for this system.
Water treatment equipment is installed after the hydraulic accumulator. It is a set of filters selected based on the results of an analysis of the water entering the house.
Combination devices can be installed here, which include several filters at once.
However, there is no point in installing fine filters and reverse osmosis here. Such equipment is installed only in the kitchen to purify a small amount of water that will be used for drinking and cooking.
If water heating is intended, then one of the branches of the water supply must be connected to a heating device.
If this seems too complicated, you can entrust the work to a construction company. Professionals will quickly and efficiently carry out all the necessary work, and the owner will only have to accept the finished structure into operation.
If your experience in arranging home plumbing differs from the installation rules outlined here, please leave your comments under the article.
We should start right away with the fact that the replacement of the water supply system must be carried out completely. Some, due to financial difficulties, are trying to change individual areas. However, this is wrong, and if the decision to replace has already been made, then work will have to be done on the entire water supply system.
So, replacing a water pipe, regardless of the amount of work, requires some tools. In addition, you should carefully consider the choice of material for the water supply. Replacement of water supply pipes can be done with pipes made of different materials. However, they all have their own scope of application.
- In the case when the replacement of water pipes is carried out hidden, it is best to use polypropylene pipes that are reinforced with fiberglass;
- Today, metal-plastic pipes are very widespread, but the age of metal pipes is already over. However, the best of all pipes for hot water supply at the moment are polypropylene. They are better than metal-plastic ones in that the latter become unusable when the temperature changes are repeated many times;
- As for the connections, they need to be made with your own hands in accessible places so that in the event of an accident they can be very easily reached and repaired;
- Replacement of water pipes in an apartment must be accompanied by replacement of shut-off valves. You need to choose only those taps that have a ball mechanism;
- As for pipes, for water supply you need to use only those that fit its characteristics. For example, the temperature of the incoming water in the apartment, the quality of this water, the availability of material resources;
- As already mentioned, polypropylene products are the best option for hot water supply. They are able to withstand media temperatures up to 80 degrees, are easy to use and have an optimal price/quality ratio.
Advice! When choosing plastic pipes, special attention should be paid to their markings, since there is a type of product that is intended only for cold water supply systems.
- Replacing the water supply system in a house with your own hands is often done because the old water supply system could not provide consumers with normal pressure. There could be a lot of reasons for this. In order to ensure normal pressure even with very low pressure in the system, a device such as a booster pump is introduced into the new circuit;
- To purify water, it is necessary to install special filters. They can be part of the risers, or removed separately. It must be said that coarse filters are more suitable for risers, which will rid the water of sand, rust and similar impurities. As for thinner filters, they are placed directly under the tap.
In addition to all the materials listed, you will need numerous rubber gaskets. You may also need special fasteners for drains and horizontal pipes.
Preparing for the installation of a new water pipeline
It must be said right away that replacing the water supply system in a house or apartment with your own hands begins with preparing a plan.
To do this, draw a diagram that will indicate all the dimensions of the risers, all the dimensions of horizontally laid sections, and the number of connecting elements. When specifying risers, you must not forget about the presence of a filter, if you plan to install it, and so on.
Advice! When purchasing, you should not focus on the figure that was obtained during the calculations, but 5% more.
Indeed, replacing water supply risers, like replacing other parts of the water supply system, is always accompanied by some loss of material, so there must be a supply.
When polypropylene pipes have been purchased in the required quantity, it is necessary to purchase all additional elements, that is, fittings, couplings, adapters, taps, and so on.
Removing old water pipe
It is clear that to install new water pipes, it is necessary to remove the old ones. If we are talking about a house with an autonomous water supply, then all the elements of the water supply can simply be removed separately.
If we are talking about an apartment building, then first you need to turn off the water.
Especially for this purpose, taps are placed at the entrance, usually in the structure of risers.
They must be completely blocked. Naturally, you need to turn off both taps from both the cold water supply system and the hot one.
After shutting off, you should check the water supply system for leaks. You just need to open the water. If water continues to drip from any faucet, then you need to call a plumbing team to change the shut-off valves.
In this case, the replacement must be carried out by them, since they have the right to turn off the water in the entire house or in a separate circuit in order to carry out the work.
After the shut-off valves have been replaced, you can begin to dismantle the old water supply system.
It all starts with dismantling the risers in the apartment. If there are several of them, then they are removed one by one.
In the case where the old pipeline was made of metal pipes, it is most convenient to install them using a grinder.
In those places where polypropylene pipes will be attached, metal ones must be unscrewed.
To do this, you may need a torch and an adjustable wrench. When all the elements of the old water supply system are cut down and the remains of the risers are unscrewed, the water pipes can be replaced.
Replacing risers
Installation of water supply risers in an apartment building begins with the fact that they are screwed into the old connector or screwed onto it. If we are talking about a private house, then the replacement of water supply risers is carried out together with the replacement of water supply parts that are located outside.
Advice! When choosing pipes for risers, it is better to focus on the diameter of the old ones, since the house has already made all the necessary holes for them in the walls or floor.
In houses built in the 60s and 70s, steel pipes are installed, the service life of which is 40-50 years. Most are already subject to replacement due to the expiration of their service life.
- Resistance to corrosion and aggressive environments;
- High strength;
- Environmental friendliness;
- Smooth inner surface. This feature prevents the accumulation of dirt and grease deposits, which increases service life without the need for regular maintenance.
Replacement of water pipes in apartment buildings is carried out by public utilities as a planned procedure. But most of the apartments have been privatized, and sections of the pipeline up to the shut-off valve and risers are undergoing planned reconstruction. Wiring inside the apartment is changed at the expense of the owner. Urgent replacement is required in the following cases:
- If the pipeline is worn out;
- When a leak occurs;
- When the pressure drops critically.
Water and sewer pipes are installed inside apartments after dismantling the old pipeline. The process is labor-intensive, requiring professionalism, accuracy and a lot of time. When doing it on your own, you encounter the following difficulties:
- When replacing water supply pipes, experience and the ability to use special tools for installing systems made of various materials are required;
- Replacement of sewer pipes should be carried out carefully, since it is almost impossible to disconnect the connection with the riser, caulked with sulfur, without damaging the riser itself;
- Therefore, if you are not confident in your abilities, it is better not to take risks - experienced plumbers will complete the work quickly and safely.
Sewerage installation is the connection of individual sections of the pipeline with a seal in the form of rubber gaskets. Installation of drain pipe sockets, connection of washbasins, toilets, bathtubs;
Installation of water supply - open or hidden installation of a pipeline using a press tool, soldering iron, scissors and wall chaser.
Speaking about replacing water pipes, one cannot fail to note the need to install a water consumption meter. The water meter is installed immediately after the filter and reducer, which stabilizes the pressure inside the pipeline.
