If you don't pay more attention to the acceptance of water pipes, it is likely to bury potential safety hazards, resulting in the occurrence of water leakage, seepage and other phenomena, which will not only be troublesome to repair, but also seriously affect daily home life. The following summarizes the acceptance of water pipes

first, do a good job in the pressure test

problem: some construction teams do not use the pressure pump, but only observe the leakage of water pipes with the naked eye to judge whether the water pipe joints are qualified. This cannot guarantee that the water pipe will not leak when the water pressure increases

acceptance: after the water pipe is laid, close the valve of the water meter first, and seal each outlet of the pipeline that needs to be pressurized with plugs, leaving only one inlet.

Press the air pressure in the water pipe to 6-8 atmospheres (0.6-0.8 MPa) for more than 30 minutes. During this period, observe that the pressure drop is not greater than 1 atmospheric pressure, and all joints and valves can be free of water leakage. The pipe can be sealed only after 2-3 hours of decompression

II. Measure the distance between the cold and hot water pipes

problem: if the distance between the cold and hot water pipes is greater than or less than 15 cm when installing the cold and hot water pipes according to the specification, the water heater interface and the water pipe will not be connected

acceptance: the owner can take a ruler to measure. If the pipe diameter spacing is 15 cm, it is qualified, and the error should be within 0.1 cm

III. prevent the intersection of water pipe and gas pipe

problem: the gas pipe is pressed under the water pipe, which is easy to cause water pipe leakage or gas leakage

acceptance: ensure that the distance between the gas pipeline and the water pipe is more than 10 cm

IV. avoid the problem of water and electricity

press the water pipe on the pipeline. If the water pipe leaks or water drops appear on the pipe wall, the wires in the pipeline may be soaked, resulting in electric leakage

acceptance: it is forbidden to press the water pipe on the pipeline. First, it should be divided into clean water pipe and pipeline. Thick pipes marked with red lines are hot water pipes, thick pipes marked with blue lines are cold water pipes, and thin pure white pipes are pipelines

V. It is strictly forbidden to use water and electricity in the same tank

problem: water pipes and pipelines are buried in the same tank, which has potential safety hazards. Because water is a conductor, if leakage occurs, the whole building will be electrified

acceptance: water and electricity must be placed in different tanks, with a distance of 15 cm

VI. no redundant joints

problem: there is an redundant joint near the connection of a section of water pipe, which is easy to leave hidden dangers of water leakage

acceptance: ensure that the two water interceptors are directly connected through elbows without redundant joints. How to save money in decoration? Home decoration network, free design budget quotation
