The same time as the above-
5, after installation must be pressurized test, test time 30 minutes, hit 8-10KG, test pressure within 30 seconds under pressure drop is not greater than 0.05Mpa, down to the work pressure check, infiltration is not leak.
The same time as the above-
6, the best water pipe top, easy maintenance, if the underground, it is difficult to find leakage, inconvenience maintenance.
