We choose the type of pipes
In the sanitary equipment market today, the two most demanded types are pipes: metal plastic and polypropylene. It is with the selection of pipes that the entire workflow will begin. Why is that? The fact is that the choice of the type of pipes completely depends on their gasket, as each of these types has its own way of connecting and mounting. Which of these types of pipes should I choose?
Metal-plastic
Metal-plastic is one of the most beautiful water-supply materials. In addition, thanks to the flexibility of metal-plastic pipes, it is very convenient to lay them. To rotate the direction of the pipe by 90 degrees, just simply gently bend it to prevent it from being transmitted, and everything is ready.
The connection of metal-plastic pipes is carried out by means of special fittings, fixing by means of union nuts.
Despite a large number of advantages, metal-plastic pipes have one big drawback - they are very susceptible to leakage at the junction of fittings. This is especially true for hot water pipes: after several cycles of temperature drop in the pipe, the connection weakens and a leak develops in the given place. The only thing that remains in this case - periodically, if a leak is detected, tighten the nuts on the fittings, which is not very convenient and practical.
The fact is that now, with the correct laying of pipes, they are either mounted in a wall, or a niche with a false wall is built for them. Thus, the pipes will be hidden and you will not have access to the fittings. In which case, in order to tighten the nuts of the fittings you will need to disassemble the wall, so the metal-plastic pipes for the apartment water supply are not suitable.
Polypropylene
The old kind pipes made of polypropylene for the second decade have a wide distribution in everyday life. It is usually this type of pipe called "plastic pipes".
The disadvantage of polypropylene pipes is that the joints are not collapsible, since they are welded together. The pipes are joined by soldering, using plastic fittings.
Connections of polypropylene pipes are very reliable and of high quality, therefore, unlike the previous type of material, they are not leaking. Polypropylene pipes you can safely put in the wall. For soldering plastic pipes you will need a special soldering iron, and in the procedure of soldering there is nothing complicated.
As for the self-assembly of plastic pipes, experts say Vse-Sekrety.ru, in the procedure there is nothing complicated. If you are a sufficiently masterful person, you can quickly master the features of this process.
Assembly features
Preparation of
Before starting work on replacement of water supply pipes, it is necessary to think carefully, therefore it is necessary to plan and sketch it first. Drawing a plan, you can immediately calculate the right amount and types of materials. After drawing up the plan carefully check it and, having bought all the necessary materials - start work.
If the pipes are hidden in the wall, make special niches in the wall for their installation. After that, close the water in the basement to the riser and begin the direct procedure for replacing the pipes.
Works with riser
First, replace the riser pipe. At a height of 15-20 cm from the floor you need to install a fitting-tee, which will be a drainage of water to the apartment. If the plastic pipe is removed from the bottom from the bottom to a sufficient level, then this tee can be soldered to its end, so as not to create unnecessary connections. If some of the neighbors have a metal pipe, then an adapter from plastic to a metal of the appropriate diameter will be needed.
It is advisable to withdraw a part of your plastic riser to neighbors if they have a metal one. The connection in itself is not advisable, and making it between the floors is not the best option, but uncritical. A plastic connection can be left between the plates.
Housing bend
Immediately on the branch pipe from the riser should be installed a valve, preferably plastic, as it does not boil and is sufficiently reliable.
Behind the inlet valve there is an adapter for metal, which is wound with a coarse water filter( it is mandatory).Further, after the filter, there is a non-return valve, a water meter is installed behind it, and after it - an adapter from metal to plastic.
When installing a coarse water filter, it must be placed downward so that dirt does not enter the apartment water supply, but remains in the filter. If you plan to install a reverse osmosis filter, it is installed before the transition from metal to plastic, after the water meter.
Next, use the tees and guide fittings to wiring in the right directions, to the desired number of water consumption points.
Replacement and laying of water pipes is the first thing to begin with
