Modern technologies are several steps ahead than the inventions of ten years ago. The same goes for the plumbing system. In almost every house, old pipes are actively being replaced, or they have already been replaced with new ones made of metal-plastic. And those who have not yet had time to do this will definitely give preference to this type of material. These types of products are famous for their reliability, quality, and ease of installation. The only thing that may seem unfamiliar, especially if the installation is done with your own hands, is the metal connection plastic pipes.

These pipes, made from a combination of metal and plastic, are lightweight, easy-to-use products with high chemical resistance. They are an environmentally friendly product pure material, which is able to operate under a pressure of 10 bar. This material is so flexible that the number of connectors is reduced to a minimum.

Scale and corrosion can be left in the last century, and a service life of 50 years is a good achievement modern technologies. The obvious disadvantage is high coefficient in thermal expansion, lack of fire resistance, deterioration appearance and service life when exposed to ultraviolet radiation.

Do-it-yourself methods for connecting pipes

Connecting any metal-plastic pipe requires the use of a fitting.

This connector allows you to:

• turn the product in the desired direction, make a sharp turn;
• branch plumbing system;
• connect pipes with different diameters to each other.

Fittings (Figure 1), connectors for metal-plastic pipes, there are different ones. Depending on the type of use, the joining process is carried out using a crimp nut or a press.

It is important to note: pipes that are laid covertly require the use of only a press fitting, and access to other connection points must be free.

To connect such structures with your own hands, you will need help:

• pipe cutter;
• calibrator and bevel remover;
• adjustable wrench or open-end wrenches;
• press jaw (in case of connecting press fittings).

Before you learn how to properly connect metal-plastic pipes, you need to know how to prepare them.

The preparation process is identical for any type of connection:

• Measure the required pipe length.
• Cut the product only at right angles.
• When taking measurements, you need to take into account the length of the entrance of the structure into the fitting.
• During cutting, the product may become deformed, but the calibrator will help in achieving the original shape.
• The gauge is used to remove the internal chamfer.
• The chamfer remover helps in removing the outer chamfer.

After carrying out the above manipulations, further actions differ from the type of connection of metal-plastic pipes.

Fittings and their varieties

The methods for connecting metal-plastic pipes differ due to the type of connector.

The fitting comes in several types, the most popular are:

• compression;
• press fitting;
• push fitting.

Compression connector (Figure 2)

Connection using a compression fitting is convenient and simple, inexpensive, and can be used repeatedly. The disadvantages include a significant waste of time on the work process; connected elements can only be located in accessible places, and the connection points need to be checked periodically.

• Alignment of the product is carried out at a rate of 10 cm before and after the cut.
• The required length is cut at a right angle.
• The pipes are cleaned from the end using a reamer, and the calibrator chamfers the entrance to 1 mm.
• The nut, then the split ring are put on the product.
• The fitting becomes wet.
• The product is mounted on the fitting; it must be adjacent to the fitting. The union nut is screwed in completely. The wrench secures the nut, but in no case should you overdo it so as not to strip the thread.

Press fitting connector (Figure 3)

A very reliable type of connection that can be confidently used for installing pipes in concrete walls and under the floor. The downside is the need to use special tools, and the element cannot be replaced multiple times; its dismantling is possible only with part of the product. It is quite difficult to carry out the work with your own hands and without experience.

The joining process is carried out in the following sequence:

• The length of the pipe is cut off.
• The internal chamfer is removed by a calibrator.
• The external chamfer is removed with a chamfer remover.
• The calibrator helps to check the diameter from the inside.
• The sleeve is removed from the fitting to check the fitting ring and its gasket.
• The sleeve, after checking, is inserted back into place.
• The pipe must be inserted into the fitting until it stops; it must be visible through the hole in the sleeve.
• The sleeve is inserted into the fitting connector, the connection goes all the way.

Push-fitting connector (Figure 4)

This type connections for water supply structures have a number of advantages:

• opportunity self-installation, because serious Building tools will not be needed;
• installation takes place in short time;
• the structure can be hidden in concrete wall or under the floor.

The disadvantages include:

• high cost of the element;
• The connection of the part must be maintained for at least three hours (at this time the seal takes the desired shape along the radius of the pipe).

The joining process is carried out in the following sequence:

• The pipes are cut to the required length.
• Using a calibrator, it is used to chamfer the ends, creating an ideal hole.
• The push fitting is placed on the prepared product, inserting it all the way.
• Another product is inserted on the opposite side of the fitting (connector).
• Two products are fixed with a push fitting.

Connection of metal and metal-plastic pipes

In practice, craftsmen often have to deal with the task of connecting metal-plastic pipes with metal ones. Two important assistants are used in the work: a gauge and a compression fitting. You will also need a thread, a washer with a nut, and a cone.

A push-in fitting is a connector that is in a good way for connecting pipes with different diameters, where some elements fit the size metal product, and the second element is the size of the metal-plastic product.

The fitting is selected in accordance with the diameter of the metal-plastic pipe, and the thread is metal.

Connecting metal-plastic pipes to metal pipes requires the following steps:

• The metal tube is wrapped in tow.
• After winding, the fitting is put on.
• A nut and washer are placed on the edge of the metal-plastic product.
• The two products need to be connected and the nut must be tightened.

For correct bending metal-plastic construction can be used following methods:

• normal bending with hands;
• using a spring, which is inserted inside and makes it easy to bend in the desired direction without defects;
• a construction hair dryer gently heats up the product and makes it flexible, but if the part is overheated, the plastic will melt;
• A pipe bender is a specially created tool for the purpose of bending a product of any diameter.

Connecting pipeline parts is not a particularly difficult task. Plumbing, underfloor heating system requires preliminary preparation, adherence to technology, understanding of how metal-plastic pipes are connected, selection of quality metal-plastic materials and connectors.

To save money when installing pipelines, the connection of metal-plastic pipes must be made in accordance with mandatory rules. Despite the fact that the price of components for this type of pipe is significantly higher than for polypropylene analogues, metal and plastic pipes today continue to be widely used in the construction of water pipelines and.

Metal-plastic pipes combine the advantages of two materials:

• the metal in the composition of such a product provides it with strength;
• plastic provides flexibility to the product.

Since you can connect metal-plastic pipes different ways, then you need to understand the features of each, and our article will help with this.

Connecting metal-plastic pipes to each other

Connection using compression parts

Basic rules (the work is not difficult, so you can do it yourself):

• With this connection method, it is assumed to use special crimp fittings (connectors for metal-plastic pipes) made of brass. The part, which in this case is used to connect pipes, is a prefabricated structure - a union nut, a fitting and a split ring.
• A wrench is required to get the job done.
• The compression fitting can be disassembled if necessary and then reused.

Operating procedure:

1. prepare a pipe of the required length;
2. align the workpiece section at a distance of 10 cm before and after the cut line,
3. cut the pipe according to the markings using precision scissors, which are positioned at right angles to the axis of the pipe;
4. check the integrity of parts and gaskets;
5. put on the nut and then the fitting ring;
6. process the end of the pipe with a reamer - the internal chamfer is removed with the calibration side, and the external chamfer - with the other side;
7. use fittings for connection (the pipe must be pushed onto the fitting until it stops);
8. screw the union nut onto the fitting by hand and then with a wrench so that 1-1.5 turns of thread remain free.

When tightening the nut, you must be very careful so that the ring does not burst.

Connection using special press fittings

There are ways to connect metal-plastic pipes that allow for high-quality installation of a heated floor system, as well as hidden communications. One of them is to ensure the connection of metal-plastic pipes using press fittings. This connection is more reliable compared to the option when compression parts are used. To perform the work you will need a special tool -.

To know how to correctly connect metal-plastic pipes, you need to clearly understand the entire process of making the connection:

1. it is necessary to calibrate the cut edge of the pipe - remove the outer and inner chamfers;
2. check the pipe diameter with a calibrator;

1. check the presence of O-rings in the fitting, as well as the presence of a dielectric gasket;
2. place a crimp coupling on the edge of the pipe;
3. put o-rings on the fitting and insert it into the pipe;

1. crimp the steel coupling using press pliers (this tool should include liners for pipes of different diameters). When crimping a steel coupling, you must ensure that the side of the sleeve is in the recess of the press nozzle.

When making a press connection of metal-plastic pipes, it is not advisable to press the steel coupling twice.

If the press fitting has a coupling attached to it, then it is immediately placed on the pipe, and through the hole in the coupling, control the depth of its seating.

Connection using push-on fittings

With this method of connecting pipes, you will need, in addition to press pliers, an expander to expand the diameter of the pipe. The result is a permanent connection. It can be used when hidden installation pipelines, including when pouring concrete.

When carrying out work it is necessary:

1. cut the pipe;
2. place a coupling on the edge of the pipe;
3. expand the edge of the pipe using an expander;
4. place the fitting on the edge of the pipe;
5. press the coupling;
6. the fitting is tightened onto the fitting, ensuring a reliable tight connection.

Application of a hybrid connection of metal and metal-plastic pipes

How are metal-plastic pipes connected to a metal riser? In this case, a hybrid connection is used.

For this job you will need a gauge as well as a compression fitting. If the products have different diameters, you should select a thread that matches the diameter metal pipe, in this case, the washer with nut, cuff and cone must correspond to the metal-plastic pipe.

The work is carried out in this order:

1. you need to wrap tow on a metal pipe;
2. screw the fitting onto it;
3. Place a washer and nut on the metal-plastic pipe;
4. calibrate the edge of the pipe, put it on a cone screwed to a metal pipe;
5. Using an open-end wrench, carefully tighten the nut (the washer tightly squeezes the metal-plastic pipe).

You can and should make high-quality connections of metal-plastic pipes yourself. However, all work should be carried out in such a way that the connection technology is carried out accurately. Wherein Special attention will need to be given and .

The variety of pipes for heating and water supply makes you think about their choice. Especially if the work is done independently. But this is only the first stage of the highway installation process. Often people who engage in self-repair, questions arise regarding working with metal-plastic pipes. Each pipeline has its own nuances and assembly rules. When installing metal-plastic pipes with your own hands, you need to know the features of their connection and fastening. After all, the reliability of a heating or water main largely depends on compliance with the technology and the quality of the work performed.

Features of connecting metal-plastic pipes

General information about metal-plastic pipes on the domestic market:

Option #2 - push fittings

No need additional tool for connecting pipes using push fittings. To connect, the pipe is inserted into the push fitting until it stops. The end of the pipe should be visible in the viewing window. After connecting the entire main line, the water is connected. This pushes and clamps the fitting wedge, which prevents leakage.

Advantages:

• ease and speed of use;
• no additional tools are needed for work;
• permanent connection;
• durability;
• suitable for bricking
• the finished connection can be rotated.

Flaws:

• high cost of push fittings;
• a waiting time after installation of three hours is required.

You can watch the video in more detail about this type of fitting:

Option #3 - collet fittings

Connection of pipes from different materials performed using a collet fitting. If the pipes different sizes then the thread of the part must correspond to the metal product, and the remaining components to the pipe are made of metal-plastic.

For pipes of different diameters, take a fitting corresponding to the dimensions of the metal-plastic pipe, except for the threaded part. It is selected according to the size of the metal pipe

A fitting is put on the metal pipe, first wrapping it with tow. A nut and washer are placed on the edge of the prepared metal-plastic pipe. Then connect them together and tighten the nut.

In some cases, metal-plastic pipes are used for installation of heating systems. You will learn about the pros and cons of these and other types of pipes in our material:.

Fastening metal-plastic pipes to the surface

When working with metal-plastic pipes, you need to know how to mount them to the surface. To secure the pipes you must use special clips. They are selected taking into account the size of the pipe itself. First you need to install the clip. Its fastening is carried out using self-tapping screws or dowels. To avoid sagging of the line, the distance between adjacent clips should not exceed one meter. Pipe bends must be secured on both sides.

To avoid sagging of the pipeline, the distance between adjacent clips should not exceed 1 meter. The turn of the highway in the corner of the room must be fixed on both sides

How to bend a metal-plastic pipe correctly?

The advantage of metal-plastic pipes, among other things, is the ability to bend them in the right place. This helps reduce the number of fittings used. This feature is used when it is necessary to make a turn and install heated floors. You can bend a metal-plastic pipe in 4 ways:

• hands;
• spring;
• using a hairdryer;
• pipe bender

Option #1 - bending pipes with your hands

This method requires dexterous hands. To learn how to bend a pipe without any tools, watch the video instructions:

Option #2 - a spring will help avoid defects

There is a commercially available spring specifically designed for bending pipes. It is inserted inside the product. After this, bending is done with ease and without defects. The size of the spring is selected according to the size of the pipes.

Using a spring to bend metal-plastic pipes helps to avoid defects and damage to the product. The spring size must match the pipe size

Option #3 - using a hair dryer

Metal-plastic pipes become more pliable when exposed to heat. To heat them up, use a hair dryer. You just need to do this carefully so as not to overheat the plastic. After heating, the pipe bends in one movement.

Option #4 - pipe bender for the master

And yet, if you are a beginner master with no work experience, it is better to use. He will help without special effort bend a metal-plastic pipe of any size. A crossbow pipe bender is available for sale. To use it, just set the bend angle, insert the pipe and bring the handles together.

If you do not have experience working with metal-plastic pipes, it is better to use a pipe bender. A special crossbow pipe bender helps bend the pipe at the desired angle

Find out what advantages a metal-plastic pipe has, and whether it can be chosen for installing a heated floor:.

It is clear that without effort it will not be possible to create high-quality plumbing or heating. Any work that you will do with metal-plastic pipes, from choosing a product to checking the functionality of the system, must be treated responsibly. Only in this case can the durability of the water supply or heating main be guaranteed.

How to connect metal-plastic pipes

In our time, absolutely everyone needs to provide themselves with heat, drainage and supply of water. To organize such communications, it is necessary to properly establish wiring of appropriate quality. The most recent developments in the field of communications are metal-plastic pipes. To carry out the necessary wiring, you need to connect metal-plastic pipes. Connecting such elements requires experience and knowledge of the sequence of plumbing work.

Common types of connection

When laying, metal-plastic pipelines constantly need to be turned, branches must be arranged somewhere, or their diameter must be changed. To tightly fasten metal-plastic pipes, special devices such as fittings should be used. There are fittings various types and are classified according to various parameters.

According to one classification, fittings are divided into:

1. Straight - for carrying out the usual connection of elements with the same diameter in cross-section in any direction.
2. Transitional - serve primarily to change the diameter of the pipeline.

According to their function, the connecting elements of metal-plastic pipes are:

1. Angular – they can change the angle of movement to 45 ̊ or 90 ̊ or 120 ̊.
2. Couplings – normal connections in a straight line.
3. Type of plugs - form a dead-end end.
4. Tee - for equipping one branch from the main pipeline.
5. Cross-shaped - for equipping two branches from the main pipeline.
6. Fitting type - metal-plastic elements are connected to more flexible hoses.
7. Other types are possible.

The most basic classification you need to know to make a connection:

1. Press fitting. It has many advantages, since it can be installed at home independently. It is also possible to simply dismantle it at any stage of work.
2. Compression connection elements. Such a connection does not require further disassembly, so installation is somewhat more complicated and the structural elements are more solid. They are arranged for walling up wiring in walls or under flooring. With this connection, crimp or inflatable couplings can be used.

The last classification indicated should be considered in more detail.

Installation work on connecting metal-plastic pipes

To carry out installation, the technology of fastening metal-plastic elements must be strictly observed. The above methods should be considered in detail.

The first method of installing elements is connection using a press fitting. First you need to get acquainted with its constituent parts. The press fitting is equipped with a fitting with two O-rings installed as gaskets. The fitting is needed to insert it inside. The press fitting kit includes a union nut and a brass ring, equipped with a cut on the outside; the ring will compress the pipe. During installation, you will need to tighten the nut, while the brass ring should press the element very firmly against the fitting.

The disadvantages of metal-plastic pipes are that they are not resistant to bending and are able to retain the shape they were given. Transportation and storage of such elements is carried out in rolls, so this form can be fixed.

Before installation, be sure to straighten the pipes. In addition, they are considered a fairly fragile material.

Option for connecting metal-plastic pipes with steel crimp couplings.

Before installation, the required dimensions for the future routing of metal-plastic pipes should be taken, and after straightening, the prepared materials should be cut according to the dimensions. At each end, metal-plastic blanks should be trimmed, forming a chamfer of 1 mm per inside. The installation technology itself is quite simple. The fitting and gaskets should be lubricated silicone grease and using a gentle screwing motion, insert the fitting into the hose cavity until it stops. Tight alignment is achieved by guiding the ferrule onto the pipe with the fitting inside until it touches the outer part of the fitting. Finally, slide the nut onto the ring and connect the press fitting with two keys.

The rules for installing metal-plastic pipes using compression fittings are slightly different. This combination is made up of a similar fitting with gaskets, similar to the ferrule of the coupling and a dielectric gasket. The connection technology is as follows: first, the coupling is put on the end, then its diameter needs to be expanded using an expander. Insert the lubricated fitting into the pipe, before connecting the assembled elements, install the dielectric gasket on the inside of the fitting. This technology prevents the pipe metal from merging with the fitting material.

An option for connecting metal-plastic pipes with a tension brass coupling and a crimp clamp.

To connect metal-plastic pipes with metal ones, the technology provides for the presence of a special press fitting or adapter, which on one side will have a special threaded connection for connecting metal-plastic pipes with metal ones. On the other hand, there will be a bell, with the help of which the parts will be combined by sliding them over. The fitting must be selected from a metal internal thread for connection to a metal element. You need to remove the plug from the metal pipe or cut it with a grinder and then make the thread yourself using a thread cutter. Lubricate it with silicone and seal it, then you can screw the fitting on by hand and connect it to the metal-plastic pipe.

After supplying water to the system, you need to carefully check this connection for leaks and seal it using a wrench, without using much force.

The connection of metal-plastic pipes, as well as other types of polymer parts, is made using fittings Particularly popular today are metal-plastic pipes that can transport liquids with temperatures up to +120 degrees. At the same time, when installing a pipeline, the main issue remains the choice of a reliable and tight connection. How you can connect metal-plastic pipes, and what features the installation of a metal-polymer pipeline has - read below.

• • Do-it-yourself installation of metal-plastic pipes for water supply
  • How to properly install metal-plastic pipes
  • Compression connection of metal-plastic pipes
  • How to connect metal-plastic pipes using press fittings
  • Push-in connection of metal-plastic pipes with fittings
  • Do-it-yourself heating from metal-plastic pipes
  • DIY installation of metal-plastic pipes (video)

Installation of metal-plastic pipes may be necessary in the case of laying a new water supply system and organizing a water heating system, replacing an old pipeline, or if it is necessary to extend pipes or change the wiring.

Installing a metal-plastic water pipe can be done by yourself

Today, the following methods of pipeline installation are distinguished:

• By welding;
• Using special fittings;
• Flange connection.

Joining metal-plastic pipes using welding is one of the most difficult methods, which takes up a lot of a large number of time: welding is performed in several seams.

The simplest and quick way pipe connections accessible to everyone - using fittings.

Depending on the method of attachment to pipes, fittings can be crimped, flanged, threaded or welded. There are fittings different forms, sizes and types. But what they all have in common is that they make it possible to quickly and reliably connect one pipe to another.

There are also tap fittings that allow you to shut off the water supply. Assembly water pipes with flanges is rarely used in everyday life due to its bulky appearance.

How to properly install metal-plastic pipes

When installing a pipeline, various connectors are used: coupling, cross, corners. This allows you to make any wiring: make pipeline turns, branch lines, connect pipes with different diameters. A special spring is used to bend the pipes. Do-it-yourself installation of a metal-plastic pipeline has its own nuances.

In order to install a water supply system, it is not at all necessary to always resort to the expensive services of specialists

So that the pipeline is sealed and reliable, the installation should be carried out taking into account the following recommendations:

1. Metal-plastic should be installed only in places with limited access to sunlight (no direct UV rays).
2. Care should be taken to ensure that the pipeline is not exposed to mechanical and thermal external influences.
3. Hidden laying of a metal-plastic pipeline requires the presence of inspection hatches at the points where the pipes are connected with compression fittings.
4. Fastening pipes to the wall should be done using hangers and supports.
5. Installation of the pipeline through the walls of buildings is carried out using special sleeves with a diameter exceeding inner diameter the pipes themselves by 5-10 mm.

In addition, you need to ensure that during the installation process, scratches, dents and other defects do not form on the pipes. Metal-propylene pipes should only be unpacked with blunt objects, and a soft pencil or marker should be used for marking.

Compression connection of metal-plastic pipes

In private construction and agriculture, most often, a compression connection is used. This is done using special PE fittings with a press-fit sleeve.

The main advantage of this connection is that no special equipment is required during installation, and if necessary, it is possible to dismantle any connection

You don't need a special tool to make the connection.

Fittings with a diameter of 2-5 cm are installed manually. For larger sizes, a chain wrench is used. Wrenches can also be used to tighten fittings.

The compression technology for connecting pipes involves:

1. Pipe cutting. You need to cut at a right angle using plumbing shears for metal, technical scissors for cutting polymer pipes.
2. Cleaning pipes, removing burrs and rounding edges. The surface that will be inserted into the fitting must be clean and free from defects. Otherwise, the pipe may, over time, begin to leak. Installing the blue nut. Nut of blue color remove from the fitting and put on the pipe.
3. Installing the white clamp ring. Installation is carried out with the thickened end of the part towards the long end of the pipe.
4. Fitting installation. The element is put on the pipe and the metal crimp ring is pushed until it stops.
5. Tightening the blue nut. It is better to tighten the nut first by hand and then using a tool.

The disadvantages of compression connections include the fact that after some time they have to be pulled. At the same time, stretching fittings can be very difficult. Especially if communications are located under the floor. Otherwise, the base will have to be dismantled to carry out the work. To avoid broaching, press fittings should be used for connections.

How to connect metal-plastic pipes using press fittings

Press fittings are special devices for connecting plastic pipes, which differ high strength and durability comparable to the service life of the water supply system itself. A press fitting consists of a body with a fitting and seals that isolate the ring and ferrule. Thanks to this design, the fitting does not leak. Today there are a large number of press models that allow you to implement any pipe layout.

Compression type brass compression fittings consist of components such as a fitting, a split ring and a union nut.

Press fittings are installed quickly and easily using special tool– crimping pliers.

Pincers can be either manual or hydraulic. Before you go shopping for a tool, you should determine the diameter of the pipes.

In order to connect two metal-plastic pipes with a press fitting correctly, you need to:

1. Cut the pipe at the desired location at a right angle.
2. Adjust the diameter of the pipe and remove the chamfer using a chamfer tool.
3. Place a stainless steel sleeve on the end of the pipe.
4. Insert the fitting into the fitting pipe.
5. Grab the tension sleeve with pliers and bring the tool handles together until they stop.

You should work carefully, since it will be impossible to re-crimp the fitting, and due to a poor-quality connection, the pipe may begin to leak. Then you will need to repair the metal pipe.

Push-in connection of metal-plastic pipes with fittings

Push-in fittings are special connecting devices that have two rubber seals in their design. Thanks to this, a tight connection is achieved. These connectors are made of brass, which makes the fittings resistant to corrosion.

Fittings differ not only in design, but also in purpose, it becomes quite obvious that knowledge is necessary to select the appropriate material

Push-in fittings have a special dielectric gasket in their design, which makes them electrically non-conductive.

Even beginners can install the devices. The design of collet fittings requires the presence of a special ferrule, which allows clamping evenly without deforming the structure. After all, it is quite difficult to straighten such a pipe with defects.

There are several types of collet connectors:

• Angle for metal-plastic pipes (internal - B type and external - H type);
• Straight fitting (allows you to connect pipes in series);
• Tee (can connect three pipes together either in series or at right angles).

The push-in connection is made using clamping pliers. You can also use a special press for fittings. In this case, the pipes should be well flared before joining.

Do-it-yourself heating from metal-plastic pipes

Organization heating system from metal-plastic pipes - this is quite labor-intensive work. In order to make the connection and further connection of pipes, you will need to stock up wrenches, flaring machine and springs for bending pipes. Before you start assembling the system, you should clearly determine the location of the boiler, pump, safety group, expansion tank, shut-off equipment, radiators. It should be taken into account that attaching any shut-off valves between the boiler and the set of safety elements is strictly prohibited.

It’s quite easy to install heating from metal-plastic pipes with your own hands.

A mechanical filter must be installed in front of the forced circulation pump.

This will protect the working elements of the pump from rapid wear. The filter, like the pump, should be installed on horizontal section systems.

Today there are several heating pipe layout schemes:

• Single-pipe;
• Collector;
• Two-pipe.

The first scheme assumes the presence of fewer pipes. But the further the pipes are from the boiler, the lower the temperature in them will be. Two-pipe system suggests how wall mounting, and installation of pipes in the floor. It is more efficient, just like the collector one, in which there will be significantly more pipes in the distribution than in the first option.

DIY installation of metal-plastic pipes (video)

Plumbing is something without which it is impossible to imagine a comfortable life. Today, metal-plastic pipes are used to transport liquids, which can be connected in various ways. You can install a metal-plastic pipeline for water supply and heating yourself. The main thing is to follow the advice of professionals and pipe connection technology!
