Excuse me, do you need to keep records of the water supply of pipes (equipment) of fire hydrant system and automatic sprinkler system? Pipeline flushing record

4.2.2 Before the water supply system is delivered for use, it must be tested and recorded.

Inspection method: Observe and open valves and faucets.

4.2.3 The pipes of the production water supply system must be washed and disinfected before leaving the factory, and can only be used after sampling inspection by relevant departments and meeting the national drinking water standards.

Inspection method: Check the inspection reports provided by relevant departments.

5.2. 1 Hidden or buried drainage pipes must be watered before being hidden, and the irrigation height should not be lower than the upper edge of the underlying sanitary ware or the ground height.

5.2.5 The main drainage riser and horizontal main pipe shall be tested for ball passing. The ball passing diameter shall not be less than 2/3 of the diameter of the drainage pipe, and the ball passing rate must reach 100%.

7.2.2 Sanitary ware shall be filled with water and tested before completion.

Inspection method: after being filled with water, all joints are watertight and watertight; The water supply and drainage were smooth in the water test.

To sum up, as long as the above requirements are met, there is no requirement for time arrangement. In practical engineering, many tests are carried out alternately, especially for buildings with large building area. As long as the conditions are ripe and the regulations are not violated, all the experiments that can be done should be carried out in time, and protective measures should be taken to prepare relevant materials to prevent the experiments from being done in vain.
