Plumbing in the house of the German collecting green polypropylene welded pipes Banninger. These tubes are considerably more flexible than the cheaper analogs. Polypropylene tubes stretch from freezing water. Rigid pipe in such a situation are more likely to burst or break away from the fittings.
When installing plumbing, take into account that polypropylene tubes are considerably lengthened with increasing temperature. Thus, when heated at 50 ° F reinforced polypropylene tubes are extended by 0.3 mm for each running meter, and reinforced pipes – 1.5 mm.
For in-house plumbing, I have used fiber glass reinforced pipes d = 25 mm with 3.5 mm wall thickness for hot water and unreinforced d = 25 mm, wall thickness 2.8 mm – for the cold. On long and straight sections arranged plumbing linear expansion, compensators are placed in the form of loops or kinks U-shaped elements.
For this scheme, it takes much longer than the pipe with a consistent water supply circuit mounted on a tee-splitter. However, it is more convenient to use for all consumers which will be about the same pressure and does not fall with the opening of the valve on the other consumers, as in tee scheme. Also allows the collector circuit to service or repair some parts of the water supply without shutting down the entire house of the water.
To drain the water from the tap in the cold or service I have provided a central drain the system as well and a local drain valve in the lowest points of the water supply in the house.
Installation of water pipeline started from the periphery to the center: collecting individual branches and brought them to the boiler-water measuring site, which collected in the last turn. Complex nodes initially drawn on paper and spread elements prepared on the spot. Then all of the elements nodes chalked on a wall, to avoid confusion during assembly. Separate water supply nodes collected in advance to then set them in place.
Polypropylene tubes are cut with special scissors along the length at exactly 90 degrees. Then the dust is removed from the abutting surfaces of the pipe and the fitting by degreasing them with alcohol. On the tube, mark with a pencil at the weld depth (pipe 0 25 mm – 16 mm). If the depth is not noted and fit on the pipe socket to the end, the welding bead can be formed, narrowing the inner lumen of the tube. In some cases, the fitting and mating mark pipes are made to ensure the required angle of rotation of the tube during installation. When laying pipe through the hole in the wall of a protective cover used with latex gloves without finger talc dusting.
Subtleties welding of plastic pipes
Welding is carried out on polypropylene tubes using a special apparatus with nozzles of different diameters. The device is possible to rent. Before working on the welding unit, set it to the desired diameter of the nozzle. By incorporating it, the regulator exhibited temperature + 500 ° F.
When pipe welding first connectable part is pushed over the nozzle-welding sockets, pipes have to clap with the effort, but cannot rotated. Once I started the on the pipe and the fitting was pushed over the welding nozzle led readout 7 seconds (for 25 mm pipes), pronouncing 21, 22 … 27. The pipe is pushed up to the mark with a pencil. Then separate the pipe and fitting.
The fitting is usually difficult to takeout – it had to hold the welding machine or fix its clamp. Immediately thereafter, quickly without rotation of the pipe and the fitting, taking care not to apply excessive force.
The rooms are laid open into the mounting clips on the ceiling. This gasket has several advantages: at home cold water warms up quickly and easily drain the water without flushing water supply.
It is water – cold and hot
Mounting a water heater with a water gauge node starts with setting cylinder and a damper (surge) tank. An expansion tank avoids pressure surges and situations where the crane “spits” with overheated water vapor. Since we have water in the house – tech, we have established a red tank for heating systems. an expansion tank with a white cell type membrane for drinking water, and water with eliminating contact tank walls.
All connections for potentially removable components in the water heater measuring site I have collected on the quick coupling – American. The gauge is hooked up to prevent damage to the tank and the water supply due to accidental overheating of water in the tank and provide quick and easy draining.
While laying plumbing, I performed completely independent for about 60 hours, spread over two weeks, due to the travel of the materials, reflection on the structure, a dip in the lake and eating kebab. In the gasket in the building plumbing it took 60 m of polypropylene tube.
