Problems existing in PPR pipe arrangement

Problems existing in PPR pipe arrangement
Many consumers found that their home installed PPR pipe problems, which affect the use of water pipes. So, PPR water pipe construction layout of the common problems?
Water pipe joint, the pipe looks very normal, in fact, there is a big problem. This toilet is changed by the water hot and cold water, add a lot of water in the joint, is bound to stay hidden for the day after Water Leakage so has the following requirements in the construction of PPR pipe layout:
First, buried in the wall of the pipeline can not have joint; second, the pipeline must be smooth after treatment by the waterproof groove arc;
Third, the fixed point should use special clamp.
PPR pipe and the top surface is not fixed, PPR water pipe in the top surface must be fixed, in accordance with the regulations, should be separated by a fixed point of 50 cm. Second, the bulb is too close to the risk of being baked. In addition, the construction should ensure that the closure of the upper reaches of the household toilet water acceptance;
The hot water pipe and wire pipe not tightly connected, except water wiring buried in a wall part has no fixed interface, using special clamp, hot water pipe and wire pipe tightly together, easy deformation caused by short circuit;
Normal use, the electric wire pipe and hot water pipe have heat release, so the two kinds of pipes should keep a certain distance, so as not to heat deformation of the pipeline, resulting in short circuit.
When laying water pipes must be horizontal and vertical, because the laying of water pipes are not standardized, did not do a horizontal flat vertical, the results of the follow-up workers to operate the water pipe leak accidentally;
The laying of water pipelines must be horizontal and vertical, let the following workers can master the pipeline trend in the construction, avoid wearing. In addition, there is no need to check the ground line is prohibited in the drilling "mark before the construction of underground pipelines, so as not to break. In addition, the construction should pay attention to the water inside the tube, once the break can be found in a timely manner; if the completion of the opening of the main valve was found to be leaking pipe, resulting in greater losses.
After installation shall test the water pressure test, pressure test, the main health plug leakage occurred Water Leakage phenomenon; according to the regulations, after the water pipe laying, must pass through the pressure test, the test is not Water Leakage to normal use. Hit 8 - 12KG of air pressure, air pressure to maintain at least half an hour before being qualified.
