The connection of metal -plastic should be performed through the collector (comb), so that all water consumers are connected through individual pipes.
Metal -plastic installation is carried out using fitting elements, corners, tees, etc. D. Installation technology is quite simple.
Of the special tools, only a specialized caliber can be needed (to restore the shape of the pipe after cutting and removing the chamfer) and the cutter). The latter, however, can be successfully replaced with a hacksaw for metal.
When replacing plumbing, it should be remembered that it is necessary to create compensation loops and all connections should be in easily accessible places for timely detection and elimination of leaks.
You should also use a minimum of connections and try to lay the metal -plast into a single canvas. But at the same time, it should also be remembered that it is impossible to bend the metal -plast too sharply (it is better to use a pipe -beam).
When choosing fittings, remember that they differ in press phutings and compressive fittings. Press-fittings are more reliable, but when using them, the use of manual or electric presses is required.
So, the connection of the metal -plastic occurs as follows:
The pipe is cut off, cutter or hacksaw. A caliber is inserted into the pipe to correct ovality after cutting. A compensation of the coupling is put on the pipe (in the case of use of compensation fittings – also a pitch nut in front of the coupling). A fitting with rubber sealing rings is inserted into the end of the pipe.
In the case of a press financial, then a squeezing of the couplings with press roots or tightening the united nut should be composed when using a compressive system.
