What is the pressure standard of tap water?

1. The test pressure of home decoration is 0.5 times of the working pressure of 65438+ pipeline system, but it should not be lower than 0.6Mpa (6 kg) as far as possible.

2. The plastic pipe water supply system for home decoration should be stable at about 1 hour under test pressure. If the pointer deviation is within 0.05Mpa, the test is qualified, otherwise the water pipe may leak. The project supervisor should send people to participate in the whole process of water pressure test, and the owner should also be present.

How to test the water pressure of home improvement

1, the water pressure of home decoration is generally carried out after the completion of water and electricity decoration. When testing the water pressure, we need to block all the pipe outlets and close the water valve at the same time.

2. Connect the hot and cold water pipes in series, and then reserve two nozzles, one with a pressure gauge and the other with a special press.

3. After the preparation for measuring the water pressure is completed, you can open the press and connect the water pressure to the water pipe. When the pressure gauge reaches the specified value, we can turn off the press.

After turning off the printing press, we need to observe the value on the water pressure gauge. If the numerical value changes within 0.05Mpa after a few days, it means that there is no water leakage in the water pipe, and subsequent decoration construction can be carried out.
