How to set an angle to the metal-plastic pipe. Installation of metalplastic pipes. Tools and materials for pipe gasket

A variety of pipes for heating and water pipes makes you think about their choice. Especially if the work is made independently. But this is only the first stage of the mounting process of the highway. Often, people engaged in independent repairs arise questions about working with metal-plastic pipes. Each pipeline has its own nuances and assembly rules. Making the installation of metalplastic pipes with their own hands, you need to know the features of their compound and fastening. After all, the reliability of the heating or water pipeline is largely dependent on the observance of the technology and the quality of the work performed.

Features of the connection of metal-plastic pipes

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

Option # 2 - Push-fittings

No additional tool is required for connecting pipes with Push Fittings. For connection, the pipe is inserted into the Push fitting until it stops. In the viewing window, the end of the pipe should be seen. After connecting the entire highway, water is connected. At the same time, the clin of fitting pushes and clamping, which prevents leakage.

Advantages:

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

Disadvantages:

push-fitting expensive;
it takes an excerpt after installation at three o'clock.

For more details about this form of fittings you can look at the video:

Option # 3 - collet fittings

The connection of pipes from different materials is performed using a collet fitting. If the pipes of different sizes then the carving parts must correspond to the product from the metal, and the remaining components of the pipe from metalplastic.

For pipes of different diameters, the fitting is taken appropriate for the sizes of metal-plastic pipe except the detail with carvings. It is selected by the size of the metal pipe.

The fitting is put on the metal pipe, wrapped it for the start of the packles. On the edge of the prepared metal-plastic pipes put on a nut and washer. Then combine them between themselves and twist the nut.

In some cases, metal-plastic pipes are used to mount heating systems. On the pros and cons of these and other types of pipes will find out in our material :.

Fastening metal-plastic pipes to the surface

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

In order to avoid pipeline sagging, the distance between adjacent clips should not exceed 1 meter. Rotate the highway in the corner of the room must be fixed on both sides

How to generate a metal-plastic pipe?

The advantage of metal-plastic pipes, among other things, is the ability to bend them in the right place. It helps reduce the number of fittings used. This feature is used if necessary to make a turn and arrangement of warm floors. Bend the metal-plastic tube can be 4 ways:

hands;
spring;
using a hair dryer;
pipe bend.

Option # 1 - Pipe bending hands

This method requires clever hand. To learn how to bend the pipe without any devices, watch the video instruction:

Option # 2 - Spring will help avoid defects

There is a spring on sale, specially intended for flexing pipes. It is inserted inside the product. After that, the bending is made easily and without defects. The size of the spring is selected under the size of the pipes.

The use of a spring for flexing metal-plastic pipes helps to avoid defects and damage to the product. Size of the spring must match the size of the pipe

Option # 3 - Using a construction dryer

Metal-plastic pipes under the influence of heat become more appropriate. To heat them use a construction hairdryer. Just do it you need carefully, so as not to overheat plastic. After heating, the pipe is bent into one movement.

Option # 4 - pipe bender for the master

And yet, if you are a novice master without work experience, it is better to use. It will help without much effort to bend the metal-plastic pipe of any size. There is a pipe bender-crossbow. To use it, it is enough to set the bend angle, insert the pipe and bring the handles.

If you do not have experience with metal-plastic pipes, it is better to use pipe bender. Special pipe bender-crossbow helps to bend the pipe under the right angle

Find out what the pluses have a metal-plastic pipe, and is it possible to choose it for mounting the warm floor :.

It is clear that without effort to make high-quality water supply or heating will not work. To any work that you will perform with metal-plastic pipes, from the selection of the product before checking the system's capacity requires responsibly. Only in this case can be guaranteed the durability of a plumbing or heating line.

Installation of metal-plastic pipes for water pipes with their own hands is quite simple, if you figure it out in the scheme, the necessary materials and tools, the features of the technological process.

Advantages of metal-plastic pipelines:

High performance characteristics are resistance to high temperatures, plasticity, lack of corrosion and salt deposits on the inner walls.
Reliable connection of structures.
Long service life is at least 10 years.
Lack of vibrations and increased noise.
High-quality pipes do not support burning.
For the installation of the water supply system, minimal repairs are required.
Resistance to temperature fluctuations.

Disadvantages:

With frequent overheats, the elasticity of pipes is reduced.
Need to protect pipes from direct sunlight.
Plastic has a large expansion coefficient.

Fitting

Apressing fittings

Pipeline elements intended for:

compounds of individual pipes of both one and different diameters;
creating branches from main pipelines and turns;
connecting plumbing equipment.

The fittings are put on the sealing rings that are necessary to increase the tightness of the connection and prevent the leaks.

Fittings for crimping

Necessary materials and tools

Truborez. The tool required for high-quality cutting pipes.

Calibrator. The device that is leveling the inner surfaces of the pipes. The standard model has 3 diameters - 16, 20 and 26 mm.

After processing the edges, the pipe calibrator is hermetically planted for fittings.

Countersink. In the absence of a special knife on the calibrator, centers are used for pipes, which also allow you to cut the chamfer on the edges of the pipe.

Deploy keys. Apply to tightening nuts on fittings.

Manual or electric press. Used to squeeze pipes on crimping fittings.

Attention! The tool can be rented in the construction market.

Installation

Drawing up a pipeline scheme with applying all control points, fittings and shut-off valves. To simplify the installation work, the pipeline track can also be applied to the walls in real sizes.

It is necessary to determine the method of connecting pipes.

Crimp method

After cutting into calibrated pipes, wear a nut and a ring, insert into the fitting until it stops. Then the fitting to keep the fitting tightly, and to tighten the nut on the pipe to the pipe.

For better entry, you can not use lubricants and petroleum products, because They will not provide the tightness of the connection.

Benefits:

fully collapsible connection;
ease of installation;
lack of leaks in cold water supply networks under long service life;
long service life;
the ability to quickly replace individual pipeline sections.

Pressing

Pipes are cut by the required pipe cutter. Then calibrated, chamfer is cut on the edges.

Next, the edge of the pipe must be introduced until it stops in the press fitting (there is a special hole to control the length). Pipe, I hope for the fitting is inserted into the press (electrical and manual) and clamping to form a hermetic compound.

The crimping process takes no more than 60 seconds. Plastic locks can be removed (to give a complete type of constructs).

Benefits:

lack of maintenance;
with the right installation, the lack of leaks on the entire service life of the system;
the possibility of sewing into the walls and under drywall;
low installation work.

After installing the system, it is necessary to check its performance - to replenish the system with water. In the absence of leaks, installation can be considered successfully.

In the event of cracks in the fitting, it is necessary to replace it. In order to tighten the weakened fitting compound you need 2 divorce keys, one of which holds the fitting, and the nut is pulled up to the stop.

When small currents appear, it is necessary to tighten the nuts on fittings in a timely manner. With repeated occurrences of leaks, it is necessary to conduct an inspection and replacement of the emergency site.
In the system, it is necessary to install coarse filters (mesh mechanical) and fine cleaning.
Pipe bending, presses and other tools can be rented in a construction or online store, while saving up to 30% of the total budget for the installation of the water supply.
It is not advisable to use fittings in mind their low cost and belt of rubber bands. Find identical gaskets difficult.
The crimp connection requires inspection and maintenance at least once a year for cold water pipes.
Because The main fit of the polyethylene tube in the fitting occurs on the fitting, after a few pull-ups after the re-occurrence of the flow, the replacement is subject to the entire node with conversion in a new place. Replacing sealing gum (gasket) in such cases will not give a positive effect.
Wash the edges of the pipe during the use of the calibrator or the zenker is not necessary, because They have enough sharp knives for high-quality cut slices.
Connection sites (fittings) are not recommended to climb into the walls. After 5-7 years, press fittings can also give to flow. Free access must be organized.
Mounting work should be done carefully, the opening of the bay is prohibited from producing a sharp knife.
The length of the pipeline also includes areas that enter the fitting, the stock is up to 2%. If the work is carried out for the first time, it is necessary to take into account the material consumption of the material.
For pipes of small diameters (16, 20 mm) it is advisable to use pipe bend. Application allows you to save money for the purchase of angular fittings. Also, such a technique excludes flowing in these areas.
It is necessary to use a sufficient number of clips to fasten the pipes to the walls. The mount is produced every 70 cm. Clips must be purchased for the selected pipe diameter, because Technically assumed to snap the pipeline in the fastener bending.

Mounting Errors System

The cause of the leaks can be unevenly cut edges of the pipe, so it is always necessary to use pipe cutter to cut.
Replacing crimping sleeves on fittings for compounds of crimping is not recommended, because In this case, the fitting itself will deteriorate, there is a quick depressurization, the system life is reduced.
Cheap connecting parts from unknown manufacturers, as a rule, low quality, replace them several times much more expensive than the purchase of high-quality fittings.
Poorly tightened pipes quickly give leaks.
The system with crimp connections cannot be sewn into the wall, because This type of compounds requires regular maintenance and tightening nuts.
In case of incomplete entering the pipe in the sleeve, the probability of pulling pipes from the connection occurs.
To cut pipes you can not use the hacksaw, because In this case, irregularities and bursaves arise, the pipe can crack. To cut the champers, you can also use knives and other items, in this case the hole of the pipe is deformed. What can lead to a rapid occurrence of leaks. For cut, it is necessary to use centers and calibrators.

How to choose pipes

To select pipes you need:

determine the type of water supply system;
take into account the temperature maximum water that will leak (for hot water it is necessary to choose reinforced models);
compare the price and quality of products;
conditions for operating pipes and the estimated use of using the next repair.

How to determine the quality of metal-plastic pipes when buying

Visually pipes should not have defects - seams, cracks, irregularities. Also on the cutting pipe should not be loosened.
The aluminum layer in high-quality products does not exceed 0.6 mm, but not less than 0.3 mm.

conclusions

The correct selection of pipes and the working tool is the guarantee of high-quality installation of the water pipeline with their own hands.

Compliance with technologies allows us to obtain reliable pipelines compounds that can serve several decades.

If you plan to install metal-plastic pipes with your own hands, you need to know exactly what you do, because the material is expensive. Consider the features of plastic pipelines, laying technology, possible methods of bending, cutting and laying, types of fasteners.

Metal-plastic designs are plastic, but you need to work with them

Characteristics of pipes from metalplastic

Metal-plastic products consist of 5 structural layers:

The inner surface of polyethylene compacted at the molecular level, or from stitched polyethylene reverses.
Adhesive layer fastening polyethylene with aluminum layer.
Aluminum layer.
The second layer of glue, fastening the aluminum element with an external coating.
Outdoor plastic coating.

In the construction of goods from metalplastic popular due to their strength. The polymer layer protects the pipeline from corrosion destruction. Aluminum consisting of a pledge of plasticity and retention of the shape during operation. When calculating the pattern, accuracy is not required. All of these characteristics in the amount allow you to carry out the operational installation of metal-plastic pipes in the design of any complexity.

Compound of metal-plastic pipe

Fittings are used to fasten the parts of different diameters, filing and branching. Depending on the type of connecting part, the bonding is carried out by crimp nuts or with the help of presses.

Press fittings are used with hidden gasket of highways

Plus the use of fittings - the presence of ready-made screws of the thread, which reduces the workflow. But the vigilance should not lose, the technology of mounting metal-plastic pipes implies a filigree neat handling of the consumable material. As a rule, the hidden gasket of the communications highway is carried out, therefore it is necessary to ensure the perfect tightness of the joints.

Note: Blank fittings with a fuzzy who went threaded. If there is no choice, the use of a shaped part with disadvantages of notches is allowed, but only if the area is "defective" threads - no more than 10% of its total surface.

High-quality helical fitting has smooth ends, perpendicular to the main product, without burrs and inaccuracies on the thread.

Preparatory work

Prepare a tool for mounting metal-plastic pipes:

calibrator and fake
adjustable or horn key (if compression fittings are used)
press ticks (if press fittings are used)

The secateur (pipeline) will provide a smooth cut line, will avoid bursowns and damage on the protective coating of products during cutting. The calibrator will help to give the part of the form, flaw to the desired diameter without deformation of the sealing. Without experience or with a shortage of time, it is recommended to use electrical instruments.

To obtain smooth ends, use pipe cutter

Before assessing metalplastic pipes, regardless of the selected type of connecting parts, prepare on a simple algorithm:

the surface of the pipes are placed on the necessary divisions;

Important: When calculating the length of the segment, consider centimeters included in the fitting.

the product is cut on the markup (operate at right angles);
if the Detail has been deformed during the process, crumple it with a caliberator (it can also remove the face inside, the outer is removed by the fake).

Pick the tool for the working diameter. If the edge of the slice is sharp, process it with a sharpened metal drill with a small diameter or a round file.

Installation with compression fittings

Compression connection is suitable for open strip

When installing pipes from metalplastic using crimp (compression) fitting, make sure that all dielectric pads and sealing rings on the tail part are available. After checking, act according to the algorithm:

Pour a protracted nut on the front of the pipe.
Fix the crimp ring.

Important: If you use a cone-shaped ring, wear from a narrow edge.

Shank with effort insert into the pipe.
Seal fastening flax with sealant or palauls.
Lock the fitting with a cape nut, tighten it by adjusting the pressure to not damage the fastener, but provide complete tightness.

Tip: Use 2 keys for reliability - one hold the fitting housing, twist the nut.

Work with press fittings

Here's how to assemble metalplastic pipes using press fittings:

Remove the face from the front of the pipe.
Treat it with a calibrator.
Install the crimp coupling.
Place the sealing rings on the fitting, insert the fitting into the pipe, the place of contact of the metal elements protect the dielectric gasket.
Insert into the press clamp inserts a diameter suitable for the fitting with a fitting, expand the tick handles by 180 °.
Place the connection in the ticks, commemorate the handles and degenerate until it stops.

Flexion and fastening of pipes

Mainstrokes are fixed from metal plastic on the walls and other surfaces with the help of special clips. Such adaptations simplify dismantling of metal-plastic pipes with their own hands if necessary.

In case of deformation of the product, the calibrator will help him

Choose clips in size and diameter of pipes.

How to fix: Install the clips with dowels and screws. So that the pipeline does not resist, install the mounting to the wall at a distance of no more than 1 m. When turning and already existing curvatures, the highway is fixed on both sides.

Bend the segment of metal plastic can be hands, with a spring, a construction dryer or pipe bender:

Manually. The product is attached to the form by pressing with hands. Suitable for experienced masters, with small diameters of pipes.
The use of spring prevents deformation (stretching, breaks, uneven bend) and simplifies work. The device is inserted into the flexible part, you can bend. Spring must match the working diameter.
Hairdryer due to heat softens plastic, the product bends into one movement. The main thing is not to overlay the material.
The perfectly smooth turn will provide pipe bending. You need to set the bend angle, insert the part in the grooves and bring the handle.

Rules for working with metal

Plastic vulnerable before UV radiation, thermal and mechanical damage. Therefore, the open installation of metal-plastic pipes for water supply or other purposes is allowed only in areas where such factors are missing. Also in the open main installation of the highway after decoration of the walls.

List of rules:

If you make a hidden highway, in the overlap, pride the hatches and removable shields without sharp edges so that there is access to the place of joints and fittings.
Do not allow the chances, cuts and breaks on the pipes. To avoid scratches, do not use sharp items when unpacking pipes.
Through the walls and other overlaps, perform a pipeline using a sleeve, the diameter of which is larger than the external girth of a pipe by 5-10 mm.
Remember: Installation of metal-plastic products can be carried out at a temperature not lower than 10 °. If consumables were at a minus temperature, allow them to warm to roommate before work.

Marking up with a pencil or marker, and metal connections equip the pads from soft materials.

You can easily handle the installation of metal-plastic structures if you follow the instructions of the manufacturer and stack patience.

Nowadays, many materials are presented with which you can perform the layout of the house of the house with your own hands. The most commonly applied iron ,.

They have their advantages and disadvantages, however, for assembling water supply from metal or polypropylene pipes, special equipment is needed.

Making metal-plastic products for water pipes with your own hands is the optimal solution that allows you to save time and money.

This article will disclose the subtlety of the installation of pipes from metal plastic with their own hands, and also presented a video, a clearly showing process.

Metal-plastic water pipelines appeared on the market for about ten years ago. The material for them is the usual plastic. In this case, the metalplastic pipe has a significant degree of protection against wear and rupture.

This contributes to the design, which is a cake from several heterogeneous layers. The inner layer is the food plastic, safe when in contact with water.

The outer layer consists of multilayer polyethylene protecting it from damage. Reinforcing pipe located between plastic layers Aluminum shell, reinforced with adhesive layer.

Specifications

Pipe rolling products are produced with a diameter of 16 to 53 millimeters. The most commonly used in household use 16 or 20 millimeters.

The wall thickness depending on its size ranges from two to three and a half millimeters. They are usually produced in rolls of 50 or 100 meters.

Dignity

Flexibility - the most important dignity can be achieved by a radius of five centimeters, fully repeating the form of an angle without breaking the pipe and the use of fitting. Complex forms with a radius from fifteen centimeters are easily bent with their hands. This allows you to easily facilitate the installation of the system.
Ease. Stometer roll can easily raise one person with their own hands.
Its strength exceeds strength in places of compounds.
You can practically not fear leaks at continuous sites.
Thanks to the multilayer design, significant wear resistance has been achieved. The service life of the water supply is more than 50 years.
They are not affected by rust, the emergence of sediment sediments prevents the smooth inner surface.
If, with long-term operation of the water supply, such deposits appeared, then they can easily be deleted.
The appearance is much more attractive than metallic.

disadvantages

Metal-plastic products can not be applied outdoors, as well as allow a long-lasting sunlight on them, as they are afraid of ultraviolet radiation.
Strength and heat resistance is certainly lower than that of metallic.
Cannot serve as a grounding device, while accumulating static electricity, which cannot be reset, since metal parts are isolated in places of connection.
Require regular maintenance (suspenders) compression fittings.

Preparation for mounting

Before mounting the water supply system, it is necessary to thoroughly think over its scheme and location. First of all, it is worth noting all the points of water consumption on the plan (cranes, shower cabin, washing and dishwasher), regarding their location in the house.

Then you need to connect these points with lines meaning pipes, and it is necessary to note their diameter, the direction of water current, as well as to divide them to those intended for hot and cold water. Calculate the approximate method of the resulting scheme.

Buy pipes are necessary with a reserve of at least 10 meters, because when mounting your own hands, losses are inevitable during the assembly. If they still remain, they can always be applied while repairing or connecting new equipment.

After that, it is necessary to mark on the scheme all the connection points, as well as those places where locking devices will be installed.

Protective valves must be installed at the entrance to the house in front of the meter, as well as before each consumption device.

Having done this, you will learn the number of mounting nodes necessary for assembling the water supply system and their specification. An exemplary calculation process is shown in video.

Construction Mounting Tools

Despite the fact that the process of mounting metal-plastic pipes with their own hands is very simple, some tools will still be needed.

The service life is comparable to the warranty period of metal-plastic pipe. Similar to its indicators and parameter of the working pressure on the connection.

We offer to watch a video where the high-quality installation of metal-plastic pipes is shown using press fittings.

Take advantage of the tips, which are given in this article and video, and will be able to install metal-plastic pipes for water supply with your own hands without the slightest problems.

Entries

Water pipes made of metal-plastic pipes - the most common option of the "wiring" of the water supply in houses and apartments. They firmly reigned in this market segment. And there is good reasons for this.

On this page, we describe all the pros and cons of such a water supply, as well as in detail, we describe how to make metal-plastic pipes, how to connect them with fittings, etc.

There are several objective indicators that allow metal-plastic pipes to shut up for the belt of their competitors when the water supply system in an apartment or house:

Easy installation. With careful work, they can be performed by any person without any preparation. Almost this semblance of a designer, for the assembly of which expensive tools and special skills are not needed.
Reliability. Warranty 50 years ago confirmation. But note that it applies to pipes, and not on their compounds.
Price. One can say one thing: "Cheaper, just for nothing." Some competition for this parameter can be polypropylene pipes, but otherwise they lose.

Based on the foregoing, the plumbing on metal-plastic pipes is obtained reliable, it costs it inexpensively, and you can collect it with your own hands. Naturally, connecting to the central system, it is the prerogative of professionals.

No matter how regrettable, but each honey barrel, there is a spoon of tar. In the case of metal-plastic water supply, these are fittings.

Fitting, this is a device with which you can:

change direction;
stupid;
join
branch.

In our case, we are talking about metal-plastic pipes. If the fitting at both ends has the same diameter, then it is straight; And if different, then transition.

But these are only their varieties for their intended purpose, but according to the method of fixation, all fittings are divided into crimping and presses.

Crimp fittings. Differently called ring, or served. In those, the fixation is performed due to the conical shape, the inner surface, the crimp nut, which, when twisting, compresses the edge ring. Such compounds can be disassembled and they require periodic maintenance. Usually once a year, crimp fittings on metal-plastic pipes for which flows hot water, It should be checked and, if necessary, tighten a little. The reason for their weakening is the temperature deformation from hot water. For their installation, two gas (adjustable) keys are required.
Press fittings. Or non-maintained, fixed on a pipe by pressing a special crimping sleeve. Work is made by press clamp. They can be manual or electric. In the first cost from 4 TR, the second from 25 tr. The compound is obtained indefinitive, but with a guarantee from leaks, regardless of water temperature. Most often, press fittings are used in connections that will be molded into the walls, or with difficult access after repair.

Reliability and quality of compounds depend on the scrupulousness of the execution of instructions. But at the price ... Although the press fittings are cheaper than the crimp, but their total cost for the water supply equipment in the apartment is equal to the costs of metal-plastic pipes.

We plan a water pipe "on paper"

The most important and primary, this is a plan of water supply layout. If you have never been engaged in this, then you can make it up with a clean leaf without much difficulties, although this is satisfied with the painstaking. But everything starts from the consumer.

It is necessary to mark the places in which the cranes will be. This is a kitchen and a bathroom. With competent construction, they are usually located nearby, which facilitates and significantly reduces the cost of the water supply system. In the perfect version, if they are in adjoint premises, only one pipe will be required, from which the tee will be taken offen in different rooms.
The place of arrival in the house of water is designated. There are only two options: central water supply or private well (well). Depending on this, additional equipment may be required. In particular, when using water from the well, it is necessary to install a hydroaccumulator (above the level of consumers). From it, water is self-shot to enter the house. Such a system is preferable, for it does not require constant inclusion of the pump. The hydroaccumulator does not have to be metallic. It can be "pouring out" from concrete. And already in the house mounted:
Filter system (equipment depending on water quality).
Boiler.

Accordingly, that if the water flows into the house from the central water supply system, then the input will require only controlling instruments to account for consumption.

This is a schematic diagram. Give recommendations on the filtration system, not knowing the quality of water, is not permissible. Also belong to the water heating system. Depending on the conditions, the boiler can be electric or gas. The use of a water heater on liquid or hard fuel is not economical and associated with certain difficulties. Especially in the summer.

Required tools and materials

From the cranes, the bempwint is unwound along the wall. In places of bend or branching, cloves are clogged, and the direction changes. Accordingly, that from tees, two (or three) bemps will already go. By placing the entire system thus, it is necessary to draw its location not the wall. Can be chalk or water-emulsion.

Only after that, the beep must be removed, and to measure its length. Additionally calculate the number of fittings and their types.

Important: The resulting Pipe Metrah, increase by 10%. This is common practice.

Regarding the selection of the diameter of the pipe, there are already a prevailing opinion. Almost for all residential buildings and apartments, with an excessive enough metal-plastic pipes ᴓ16 mm. It provides a flow of up to 3 m 3 / hour. And most water counters are not designed for greater flow. Yes, and why more?

The choice of the manufacturer of metal plastic pipe is perhaps the most difficult task. In the market often come across fakes. Purchase a pipe in a solid store or from proven suppliers. We recommend to refrain from the purchase of metal-plastic pipes of Chinese manufacturers. Negative reviews are found too often. The highest quality metal-plastic pipes are produced in Belgium ( Henco.), Germany ( Frankische and Sanha.).

What will be required of the tools:

Cutter for metal-plastic pipe (from 250 p).
Caliber with zenker (from 200 p).
Conductor (from 500 p).
Press ticks (from 4000 r., But you can rent).
Two gas (or adjustable) keys.
A hammer.
Sculpture.

How to work with a tool

Caliber, restores the shape of the pipe after cutting, and Zenker removes the chamfer and removes burrs. If the caliber is without a zenker, then its work can be performed using shallow sandwich.

The conductor serves to flexing the metal-plastic pipe. It is external and inner. The use of internal in some cases is more convenient, for it does not slide in his hands. But it is not always possible, for the place of bending can be far from the end of the pipe. Therefore, we recommend to stay at the external conductor.

Press pliers will be required if you use maintenance-free fittings. We, on the basis of 16 years of experience, we recommend that the press fittings are recommended. And the reason here is one. Most tenants, in a year they forget about the service of crimp fittings. And this leads to leaks. But the choice is yours.

Consumables will require: self-tapping screws, fastening for metal-plastic pipes, tape FUM.

Mounting process of metal-plastic pipes

Starting the installation of metal plastic water supply is necessary from the source to the consumer (to the cranes). Make a cut from the roll to the nearest fitting, and cut it with a knife. Calibrate, remove the burrs and remove the chamfer. Then insert the pipe into the fitting until it stops. The press fittings have special holes, to control the depth. They should be visible the edge of the metal-plastic pipe. Then insert the fitting into the ticks, and crimp the connection.

Crimp fittings are fastened with nuts and rings included in the kit

It is quite simple to work with the press ticks, because insert the fitting "Crooked" will not work.

All press clamps have replaceable sponges for pipes of different diameters. Do not make mistakes in choosing sponges.

The process of installation of crimp fittings is slightly different. The nut first puts on the prepared trim, then the edged ring and after that, the pipe is inserted into the body of the fitting itself. Before spinning the nutWe strongly recommend that turning the fum ribbon. It takes only two or three turns. It is necessary to start from the edge of the thread and carry out the winding, holding the latitude tape. After that, moisten the thread with sunflower oil. This technique will protect against the appearance of leaks!

The nut is first twisted with their hands until it stops. And only then, holding the fitting with one gas key, others tighten the clamping nut. It should not be drawn out of all the might, but the small effort is necessary.

Installation with press ticks

Fix the metal plastic pipe to the wall follows each meter. Special attachments through the self-sufficiency are strengthened in the surface, and the pipe is inserted into them.

In those places where it is permissible, the pipe can be bent using a conductor. To do this, the conductor dresses onto the pipe, supply it from the right place, and neatly, holding the product with his hands, on an equidistant from the target distance, bend the pipe in the desired plane. Given that the radius of the bending of the metal-plastic pipe is equal to its 8 diameters, this approach is not expedient everywhere.

Checking, leakage

By installing metal-plastic pipes, connect them to the crane with the help of hoses that are included. Then go through all the route again, and visually check the integrity of the assembly.

Pay attention to tees and splitters. Sometimes, inserted by one branch, the installer forgets about fixing the pipe in another.

Open the taps at the end of the water pipeline (in the kitchen and in the bathroom). And only after that slowly, in order to avoid a possible hydrate, open the water supply faucet to the system. It is most convenient to perform this stage with a partner. It should control the water outlet in the final point. As soon as the water went, for washing pipes, let it drag it within 2-3 minutes. Then close the outlet cranes, by this you raise the pressure in the system, and go through the pipe of the pipe gasket. Check all connections. If you doubt, do a paper napkin (or toilet paper) on the surface of the fitting connections). Do not confuse condensate with leak!

We guarantee that if you fulfilled work according to our recommendations, then in 99.9% there will be no leaks. If a connection causes you a reasonable fear, then slightly tighten it.
