How long does it take to test the waterproof water in the bathroom?

After the general waterproofing is completed, the water storage test can be carried out after 24 hours, and it is observed every 6 hours, usually 4 times. That is to say, after 24 hours, the water should be stored to see if there is any leakage, and then the water spraying test or observation after rain can be carried out to see if the drainage is smooth and there is no water accumulation.
