Is it necessary to do a pressure test after the waterway reconstruction is completed? Can anyone tell me?

1. A pressure test should be carried out after the new home is renovated. 2. Water closure test method: Block the floor drain and doorway, put 5 cm of water on the ground, observe for 24 hours, and go to the neighbor's house downstairs to check. If there are problems and need to be waterproofed again, wait until the ground is completely dry before laying ceramic tiles and carrying out overall decoration. When converting a squat toilet into a sitting toilet in the bathroom, waterproofing of the toilet drain outlet must also be taken care of. It should be noted that if waterproofing has not been done again and it is not certain whether the original waterproof layer is intact, the closed water test must be done with caution. If you do a hasty water shut-off test, unexpected water leakage may occur, causing losses to the residents below. 3. Pressure test: After the waterway transformation is completed, a pressure test must be done to detect whether the waterway will leak under a load exceeding the normal hydraulic pressure. Many construction teams will intentionally or unintentionally ignore this step when completing the work. As an owner, you must insist on doing a pressure test. The method of the pressure test is: first seal all water outlets to form a loop, then connect the pressure machine to a water outlet, slowly pressurize to 0.6MPa-1.0MPa, and maintain it for 20-30 minutes, during which the pressure gauge reading drops. It is qualified if it does not exceed 0.05MPa. Check each water outlet and connecting piece for leaks during the same period of time. Before you can lay the floor, Bairui, a well-known decoration company in Tanggu, will give you the answer.
