What is water test on drainage?
A water test sometimes called a “drop test” is a low-pressure method of drain testing. It works by blocking the end of the drain with a bung, then flooding the pipe with water. The water levels are monitored to make sure they stay stable during the test.
How do you do a drains test?
First, airtight plugs are inserted in order to isolate the section of pipework that’s being tested. Using a drain pressure gauge, the pressure is set to 110mm head for 5 minutes. Next, the pressure is adjusted to a 100 mm head reading of the pressure gauge and after 5 minutes any change in head is measured.
What are the test to be done on drains and pipes?
There are three tests that are commonly performed to test leakage of the pipes and are as follows: (i) Air Test – Generally used to test underground and vertical pipes.
