From new builds to refurbishments, or just an ongoing issue it is vital that your drainage system is fully functioning.
From new builds to refurbishments, or just an ongoing issue it is vital that your drainage system is fully functioning. This includes manholes and inspection chamber with environmental legislation.
There are different methods in which you can test your drainage systems to help your identify and detect any problems.
At Kassia Drains we tend to use two methods for drain leakage investigation.
DRAIN AIR TESTING
For single pipes drain runs the air pressure test, but it can only be used to test a length of a drain that can be capped at both ends.
DRAIN WATER DROP TEST
The understanding of each test - here comes the technical part!
DRAIN AIR PRESSURE TESTING
WATER DROP TESTING
A water test is very similar to a air test in which all open connections are capped off but instead of air the system is filled with water. On the highest end of the system (due to displacement) to the bung a test is attached to the end of the bung into which the water is topped up to give a visual amount of water holding or leaving the system. Water tests are usually completed within 2 hours.
WHO NEEDS TO BE THERE FOR DRAIN TESTING?
If on site a drain test is performed in the presence of a building control officer once a section of drainage is completed. The contractor will normally perform the test prior to the official inspection to ensure the drainage will pass.
