If it seems to you that distributing pipes in the bathroom is too complicated a process, then you are mistaken. Modern technologies have turned it into a system of fairly simple and accessible to all actions, provided that you have the desire to do everything yourself.
Hot and cold water supply
First, it should to decide? What kind of plumbing fixtures and communications you will need in the bathroom (or combined bathroom):
Now count the required number of valves that block the water:
Detailed piping layout
Having defined with the number of plumbing fixtures that you intend to connect to the plumbing and sanitary, you must first purchase them. Decide where and what exactly will be located, noting their location on the floor (so that the plumber does not interfere, it is better to remove it from the bathroom after that, if possible).
Then take a piece of paper and draw a wiring diagram on it. Try to follow the following principles:
Try not to complicate the piping in the bathroom. Everything should be as simple as possible:
To assemble the system from polypropylene water pipes, you will need a special tool, colloquially called "soldering iron". It makes no sense to buy it for one-time work, it is much easier to rent it for a couple of days (this service is usually provided by specialized shops). It is quite simple to work with him, but one should not forget that he is very hot, so be careful and be sure to read the instructions if you use it for the first time. You may even need the first time an assistant who will hold the "soldering iron" while you heat the pipes and fittings, and then put him aside so that you do not burn yourself.
Fittings for distributing PVC pipes
To connect the pipes to each other, as well as turn them under corner, you will need PVC fittings (they are sold in the same specialized stores). Pick them exactly the diameter of the pipe. They are not too expensive, so take them with a reserve of 1-2 pieces in case you can not solder them exactly on the first attempt.
Connections made with the help of a "soldering iron" are one-piece, and in order to redo them, you will have to cut off the defective part. If the length is less than necessary, increase it using a "clutch".
To complete the wiring, you will need to connect to the end editions of "American" - These are fittings, on the one hand in which the pipe is soldered, and on the other, a flexible hose is connected through the threads.
The wiring in the bathroom can be done in two ways:
But with You don’t need a soldering iron pipe assembly - they are simply inserted one into the other (independently or with the help of fittings). Assembling the sewer system is quite easy and simple; moreover, it is always possible to disassemble and redo it all.
When doing wiring in the bathroom, the main thing to remember is three basic principles:
The layout of sewer pipes should always be as simple as possible. Try to connect all the plumbing equipment in series so that "intersections" do not occur, in which, while simultaneously draining water from two devices, a "jam" can occur.
Scheme of sewage and water supply
If you have any doubts that you you can easily clean the sewage through the drain holes in the bath or sink, install an additional fitting tee on the sewer pipe, closing its upper hole with a special stopper. Later it is through him that you will clean the pipes. After you close the box, do not forget to leave them access for maintenance.
When connecting the sewer pipes to each other, be sure to check that all the joints contain rubber gaskets (without them, the drains will leak and the unpleasant smell will spread).
Pipes should be inserted one into the other (or into the fitting) to the maximum possible depth.
To make the slope permanent, attach them to the walls with special clamps, thereby fixing each section.
