How to write a toilet water storage test record

Toilet water storage test: water storage start time; The end time of water storage (generally 24-48H); water storage; the amount of water level drop at the end of impoundment; Inspection under the toilet (whether there are any leaks or water traces, etc.); Toilet water storage test conclusion (pass or fail); Inspector, Recorder, Recording and Inspection Time, Recording and Inspection Unit, etc.

The closed water test, also known as the water storage test, should be filled with water, and the water should have a sufficient volume. The water storage depth of the water storage test should not be less than 20mm, the water storage height is generally 30-100mm, the water storage time is 24 hours, and the water surface has no obvious drop to be qualified. This test is generally done on the roof, bathroom or room with waterproof requirements.

In the early stage of the water storage test, it should be inspected downstairs every 1 hour, and every 2-3 hours in the later stage. If water leakage is found, the water storage test should be stopped immediately, the waterproof layer should be re-improved, and the water storage test should be carried out after the treatment is qualified.

After the closed water conditions are met, the closed water test of the pipeline can be carried out. The test is carried out from the upstream to the downstream section, and after the upstream experiment is completed, it can be filled with water downstream, and the reverse section test can be carried out to save water. The phases of the trial are described below:

1) Water injection immersion: The water level of the closed water test should be 2 meters above the top of the upstream pipe in the test section, and the water should be irrigated to the height close to the upstream wellhead. During the water injection process, the pipe plugging, pipeline, and well body should be checked for no water leakage and serious water seepage, and the closed water test should be carried out in the soaking pipe and well for 1 2 days;

2) closed water test: the water is irrigated to the specified water level, start recording, the measurement time of the amount of seepage is not less than 30 minutes, and the amount of seepage is calculated according to the decline value of the water surface in the well, and the amount of seepage does not exceed the specified allowable amount of seepage is qualified.

3) Calculation of test seepage volume: when the seepage water test time is 30 minutes, the water seepage per km pipeline per day and night is Q=(48q)*(1000 L), and Q --- the seepage water per km of pipeline per d in the formula.

Q--- The amount of seepage water in the closed water pipe for 30 minutes.

L--- length of closed water pipe section.

When Q allows the amount of seepage, the test is passed.

That's not easy, the ordinary situation is to have two people present, what time to start the water storage test (generally 24H water storage), how high the water level is the scale, every 4-6 hours to observe once, while going to the bathroom outside and downstairs to see. If the outside is a small part of the wet, then the waterproof paint should be repainted, if there is no water seepage, then the water level will not drop more than half a centimeter.

Toilet water storage test:

the start time of impoundment;

The end time of water storage (generally 24-48H);

water storage; At the end of the impoundment, the water level will be lowered;

Check under the toilet (whether there is water leakage or water traces, etc.);

Toilet water storage test conclusion (pass or fail);

Inspector, recorder, record and check time, record and check list, etc.
