How to do the suppression test of decorated water pipes? How to charge?

The water pipes will be suppressed after the waterway decoration at home, which is also one of the methods to test whether the water pipes and pipelines are in good condition and reliable. If the water pipes and pipelines are not well connected, there will be leakage, leaving hidden dangers for domestic water use. So how to do the suppression test of the decoration water pipe? How to charge? Let's see the answers we will give you one by one.

Test method for pressure suppression of decorative water pipes;

1, tool preparation

Pressure gauge, water tank and connecting hose, etc.

2, pressure measurement method

(1) Connect the hot and cold water pipes together with hoses. This hot and cold water will form a circle and become a pipe. The pressure tester can be connected to any water outlet. At this time, the pressure pointer is 0 pressure;

(2) After all the water pipes are welded, the pressure test can be carried out. Before the pressure test, all plugs should be plugged and the inlet main valve should be closed;

(3) When measuring the pressure, shake the pressure rod of the jack until the pointer of the pressure gauge points to about 0.9- 1.0, that is, the current pressure is three times of the normal water pressure;

(4) Keep the pressure value for a certain time. The difference is that the pressure measuring time of water pipes is different. The welding time of PPR, aluminum-plastic PPR, steel-plastic PPR and other pipelines is 30 minutes (it can only be exceeded, not less). Aluminum-plastic pipe is the kind of copper joint, and the time is 4 hours (half a working day). Galvanized pipe is 4 hours and a half working days.

3, the result judgment

During the pressure test, the connectors and internal connectors should be checked one by one, and the plug should not leak water. Some people say that the plug leaks water, which is a lie. The water seepage of the plug directly affects the pointer of the pressure tester. Who knows if the needle will keep falling? The pointer of the pressure tester does not drop at all or the drop range is less than 0. 1 within the specified time, indicating that the water pipeline is good and the pressure tester is in normal working condition.

Charge standard for suppressing decoration of water pipes:

The cost of water pipe suppression is not great, and some communities can ask the property for help. At this time, the water pipe suppression is free; In addition, the owner directly asks outsiders to help suppress it, so the water pipe suppression fee is the door-to-door service fee or the staff salary fee, and the fees in each place are different, roughly around 400 yuan.
