After curing, start to drain water. After the test, use a putty knife to shovel off the foam glue.
There is no strict requirement for the height of the water test, cover the mouth of the sewer pipe, and it is almost two centimeters above the ground. Keep it for 24 hours, and see that the top surface of the downstairs is not leaky. ，
See where the water is coming out and turn it off first. Then find the property to come and deal with it.
Just find some fine sand or dirt to use outside – just clean up after the closed water test!
Do you mean the closed water test? If so, pour water underground for 24 hours, go downstairs to see if it's leaky.
Here's a trick for you, put sand in a plastic bag and put it on the floor drain. Hope it helps. >>>More
