DIY water wiring

What can make you think about the installation of a new water supply? Morally and physically obsolete, rotten rusty pipes, the upcoming major repairs in the apartment will not be stupid to use the situation and bypass such an important point as communication. Well, there is also an entrance to the new building, where there are only summarized trunks in the bathroom and nothing more: neither pipes of water wiring, nor sewer pipes, i.e. Everything is left at your personal discretion, how and what to arrange. Wiring of water in the apartment, although it is complex, but quite feasible for a person who has at least a drop of engineering and straight hands. If you decide to do all the work yourself, you will have to solve more than one issue and make more than one choice before starting the installation. Therefore, in this article we will discuss which is better to choose a water wiring scheme, from which material to choose pipes, what installation rules for certain types of pipes and how it is performed.

How to make water wiring: open or hidden way

Probably, the very first question that arises for apartments arises is to smile pipes into the walls or perform wiring in an open way. For small rooms, this question is critical, since the pipes laid in an open way will not make it possible to place all the equipment in the bathroom that we would like. Just don't have enough space. In large rooms, you can do as you like, but it is important to know a number of restrictions.

Important! You can not make any detachable joints on any pipes into the walls. For example, metal -plastic pipes with squeezing fittings, transition couplings from propylene on threads, any American, nipples, barrels, threaded couplings and another should be openly to be able to serve and repair them.

Can be fried into the walls: copper pipes, polypropylene pipesand metal -plastic with press compounds. As you can see, the wiring method already imposes certain restrictions on the ability to use certain materials. So when choosing how to make water wiring, you can build on which pipes planned to use, and take into account the pros and cons of both wiring methods.

Advantages of water pipes walled into the walls of pipes:

1. All the pipes are hidden from the eyes, nowhere can you see anything in the end a beautiful neat type of room.
2. You can arrange furniture and devices without loss of useful area. Otherwise, the pipes are taken about 10 cm along the walls.
3. In case of fire, the plastic pipes of the water supply will not be damaged.

Disadvantages of laying water pipes in strobes:

1. Restrictions on the choice of pipes material and the method of their connection and installation, since you cannot hide any collapsible joints.
2. The complexity of preparatory work. The stroke of the walls is not only long and difficult, but also dusty.
3. The complexity and complexity of the installation of pipes. They must be assembled with exceptional accuracy, strictly under the strob, otherwise at the most inopportune moment, it turns out that it is necessary to get.
4. It is impossible to carry out repair work without destroying wall decoration and dismantle the plaster and pipes.
5. In the event of a leak in the pipe, this will be found out only when neighbors come from below with angry threats and reproaches.
6. If you need repairs, you will have to make a new cosmetic repairs in the room, since the walls will be dispersed. These are additional not only labor costs, but also financial losses.
7. It is impossible to inspect the pipes, check their condition or suspicion of leakage.
8. You can accidentally damage the water supply if you forget where exactly the pipe goes, when you have to drill a hole to fix the boiler, mirror or other device.

Obviously, the hidden installation method has a significant number of disadvantages. So before you choose it, you need to carefully weigh everything. Do not forget that water communications belong to the class of dangerous and require constant control.

Advantages of the open method of laying water pipes:

1. An open method can be mounted on any pipes. There are no restrictions.
2. Do not have to stroke the walls, which means that the installation is less time -consuming.
3. The simpler installation of pipes, since, without attaching to the strob, it is easier to put up everything.
4. Easy, simple and undesirable dismantling of the entire water supply. At the same time, the decoration of walls and floor will not suffer.
5. At any time, control of the condition of the pipes is possible.
6. When a leak appears, it is immediately visible, it is also easy to notice it by the presence of a puddle on the floor.
7. The water supply can be improved at any time, add a line without spending time and funds for complete dismantling and repairing the premises.

Disadvantages of an open water supply:

1. Non -casual appearance. Although the pipes can be hidden into the boxes and carefully sewn up, but this design is not suitable for all rooms. In some, such boxes can be beautifully beaten or even create whole niches and mini-claders for storing all baths.
2. Reducing useful area. For example, you can’t move a washing machine or underwear basket close to the walls.
3. In the case of a strong fire, plastic pipes will burn, and you will lose the water supply. True, the water will extinguish part of the fire, but this will not solve the problem.

To make the right choice, measure the room and calculate everything up to a centimeter, what where it will become and what will not fit. Perhaps it will be more correct to give up a free place and perform open installation.

Water wiring scheme

An important question of the wiring scheme. Probably, everyone has come across at least once with this situation: you wash in the shower, enjoy a beautiful warm stream of water, and at that moment someone washes water in the toilet or turns on the tap in the kitchen and starts to flow boiling water from the shower. Unpleasant and dangerous. To prevent this from happening, it is necessary to choose the right wiring scheme and pipes diameters. By the way, if you want to purchase acrylic baths, you can go to the store and buy a high -quality bath at a reasonable price.

In total, there are two schemes for wiring water pipes, but the third is also possible, which is the essence of the combination of these two.

Consistent scheme Or, as it is also called trigemaker, where all consumers are connected sequentially. Those. There is one pipe along all consumers from the highway and there is a tee with each, which takes the pipe to this consumer, and the main pipe goes on, and the next consumer is again put a tee, etc. This scheme is fraught with the fact that if several consumers are used at once, the latter will have the lowest pressure in the system. As a result, the situation described above may be.

Collector schemeit is performed somewhat differently. The pipe connected to the highway is included in the collector, from which a separate pipe goes to each individual consumer. At the entrance to the collector and at the output of each pipe, a ball valve is installed. This allows you to repair one pipe and one consumer without prejudice to others, i.e. You can simultaneously repair the toilet and use the sink in the kitchen or bathroom. Also, the pressure will be distributed more evenly and will not be a situation when boiling water suddenly pours or pressure drops sharply.

But with all its advantages, the collector scheme has a lack of more materials (pipes, fittings and cranes) and more space to place it all. So the installation according to this scheme costs somewhat more expensive.

When choosing a pipe laying scheme in the apartment, you should also take into account the water distribution scheme in the house. For example, when planning, where the main highway approaches the bathroom, and the return is in the kitchen (i.e. the water passes through all the apartments on the upper floors, and then goes down and passes through the kitchens), you can not be particularly wake up and simply connect in the kitchen with consistent connecting the sink and dishwasher. But the wiring in the bathroom will depend on the number of consumers.

In principle, if everything is done correctly, with knowledge of the matter, then the trigeminal system can ensure the correct distribution of pressure so that there are no unrequited losses of the pressure of cold water.

Cold water wiring It should look something like this: the first tee should be with a shower in the bathroom, the second for the shower in the toilet (if any), the second to the sink in the kitchen, and then the tanking to the toilet, washing machine and the boiler. Since the last three points do not depend on hot water, do not suffer from temperature differences, but are connected only with CVS. There are such layouts of apartments that the first tee, well, is simply obliged to take to the toilet. In this case, you can cheat. For example, if the wiring was performed with a pipe of 25 mm, in the direction of the toilet make a tee with the transition to a pipe of 20 mm, then put a ball of a fecal tap, and then make a divert with a narrow pipe of 10 mm. So the water in the toilet tank will be slow down, and the pressure drop in the DHW system will not be felt.

You can organize a semblance of a collector using pipes of different diameters. For example, after entering the pipe of 25 mm and all of the required reinforcement (ball valve, coarse cleaning filter, counter, check valve), we put the pipe with a diameter of 32 mm, and we already lead to consumers to consumers 20 mm pipe.

Hot water wiring It may look something like this: a tee with a discharge to the soul in the bathroom, then to the soul in the toilet, and then the sink in the kitchen. Usually there are no problems with this. The main thing is to install a check valve on the HVS highway so that hot water does not go into the cold riser. You can install OK and DIS to a couple, but this is not necessary.

When choosing a water supply scheme in the apartment, also keep in mind that the collector scheme will be almost impossible to waln into the walls (you can on the floor), and the collector itself must be open to the possibility of maintenance and access to ball valves.

What pipes for the water supply to choose

More recently, such a question did not stand at all, since there was simply no choice. Today, the eyes scatter from the choice, since the market was able to offer not only pipes from various metal, but also plastic ones with various characteristics. So, what water pipes can be purchased.

Steel galvanized pipes The good old proven option. They are persistent, durable, durable (up to 25 years), but over time they rust, growths appear inside, from which the quality of water suffers. In addition, the installation of such pipes is associated with some difficulties: you will have to cut the thread and twist the pipes among themselves. At the same time, everything must be calculated with an accuracy of a millimeter.

Stainless steel pipes Durable (up to 50 years) and are not afraid of rust. But their price is large, and even more the cost of fittings for them, although the installation is not so complicated. Very simple repairs. A universal option is most often used for towel rails.

Copper pipes One of the best universal options, but very expensive. Durable, smooth, are not amenable to corrosion, are not afraid of increased pressure and harmful impurities in water, microorganisms are not starting, they are also indifferent to ultraviolet light. The most durable (up to 70 years). The installation is not very complex, the only drawback of the price.

Metal -plastic pipes The cheapest, but fittings for them are of average cost. Serve 25 30 years. Easily mounted, bend, are not afraid of rust, deposits do not accumulate on the walls. But at the same time, metal -plastic pipes are afraid of too high temperatures (more than 95 s), and pipes with fittings cannot be bent.

Polyethylene pipes Quite strong, elastic, average in price, fittings for them, too, have been serving for more than 30 years. Installation is quite simple to welcome each other. Such pipes do not bend and do not withstand high temperatures, so they can only be used for cold water supply. There are still pipes made of stitched polyethylene, they are a little more expensive, but can be used for DHW.

Polypropylene pipes Recently, they are enviable for several reasons: they can be hidden in plaster, it is not necessary to often check them, universal (HVS, DHW, heating, warm floors), durable and durable (about 50 years). It is connected by welding, for which a special welding machine and scissors will be required. For hot water supply, reinforced pipes (aluminum or fiberglass) are used.

The choice entirely depends on the wishes of the owner and on the scheme and method that were selected.

DIY water wiring

Anyone who is confident in their abilities and has minimal engineer skills can replace or make a new tap wiring with their own hands. But at the same time, it is better to coordinate the wiring scheme with a professional. Perhaps he will notice the shortcomings or give sensible tips on the materials and diameters of the pipes.

We make a water wiring scheme in the apartment

It is necessary to start work to replace the water supply with the preparation of the scheme. First of all, we are determined with the installation method: open or closed. Then we make a diagram. It can be drawn on paper by hand, but absolutely everything must be indicated: the size of the room, installation sites and dimensions of the devices and plumbing in the bathroom, the place of pipe laying, their diameter and exact length to each node, it is necessary to specify all the fittings, their type and size , the installation site where the pipe bends, where it turns. Well, that's all. Before starting installation, this scheme should be shown to a professional. It makes no sense to start the dismantling of the old pipeline before the final scheme is ready and all materials are purchased.

Choosing and buying the required materials: pipes, fittings, tools

After drawing up the circuit, it is necessary to calculate how many and what pipes, fittings and other reinforcement will be required. It is advisable to buy everything with a margin of 5 10 %, since anything you want can happen during the installation process. Of course, the price will depend on the chosen material of the pipes and the laying method for wiring water in the apartment. The collector scheme immediately increases the laying of the pipeline several times. The average in cost and optimal in characteristics can be considered pipelines from metal -plastic pipes and polypropylene. Copper pipelines will be more expensive from stainless steel.

Only after all materials and installation tools are bought, you can proceed to dismantle the old water supply. If it is planned to change not only the inner pipes, but also the leading trunks, then it is necessary to block the supply of water to the riser. You cannot do this yourself, only a plumber from the management company.

We carry out the installation of a water supply of metal -plastic pipes

Metal -plastic pipes can be connected in two ways: with crimping fittings or press compounds.

Clotted fittings connected by metal -plastic pipes can only be used for open pipes. The connection is performed as follows:

• We measure and cut off the pipe of the required size.
• Using a fascinator calibrator, remove the chamfer from the pipe.
• We put a nut from a set of fitting on a pipe.
• Then we insert the ring.
• We insert the fitting and squeeze with two lacture keys.

This compound is considered threaded, which means that it is subject to leaks, the pipes must be checked and pulled up at least 1 time per year.

Connection with press fittings It can be laid as open, so closed method. It is performed as follows:

• We measure out and cut off the necessary section of the pipe.
• We calibrate.
• We insert the pipe into the fitting and criminalize with the help of a manual press.

The resulting connection is durable, capable of withstanding a sharp drop in pressure, but non -devastated.

Metal -plastic pipes bend, maximum bending radius of 3 5 pipe diameters. The pipe section to the fitting should be even at least 5 7 cm.

We carry out the installation of the water supply from polypropylene pipes

For cold water, we use pipes 25 mm in diameter with a wall thickness of 2.8 mm, and for hot reinforced pipes with the same diameter, but with a wall thickness 3.2 mm.

• We cut the pipes into the necessary segments with special scissors, hold them strictly perpendicular.
• On the pipes we mark the welding depth (it depends on the depth of the fitting), for example, 1.6 mm.
• We remove the middle layer of the pipe to a depth of 1 2 mm.
• We install the nozzles of the required diameter on the welding machine and turn it on, setting the temperature of 240 260 C.
• We start welding when the bulbs on the welding machine go out. Both pipes or pipe and fitting are pushed into the nozzles of the welding machine, without scrolling, to the mark on the pipe.
• After 7 seconds, remove the pipes. We start the countdown from the moment the pipes were started on the nozzles and started moving along them. When we remove the pipes from the welding machine, it is necessary that the second person holds it, as he is very light.
• Gently connect the pipes among themselves (or the pipe and fitting), planting one on the other. In no case do we make rotational movements. You need to perform everything smoothly and quickly.

We are waiting for a few seconds until the connection is cooled, then the pipes can be used. A beautiful perpendicular compound should be obtained, if you are not satisfied with the result, then the connection should be cut and the entire procedure is re -cut, cutting off the tired piece.

Wiring water in the apartment with your own hands ends with checking the assembled pipeline, i.e. Statement with a special device. Only after the good results of checking the joints and pipes for strength under high pressure are obtained, you can connect water. All pipes and compounds should be examined for leaks.
