Drain Testing

Kassia Drains

There are different methods in which you can test your drainage systems to help your identify and detect any problems.

No cross contamination between foul sewage and rain water systems.

At Kassia Drains we tend to use two methods for drain leakage investigation.

DRAIN TRACING

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

For complete drainage system check includes chamber and gullies. This test is more involved as it’s able to test a whole drainage system.

The understanding of each test - here comes the technical part!

DRAIN AIR PRESSURE TESTING

Air testing is completed by placing a bung in all open connection in the drainage system and having one test subject into the bung you then attach a manometer.
To this manometer a hand pump is then attached into which you can increase the pressure from within the system (providing there is no leaks) The recommended pressure is set to 100mbar and left for a minimum of 5 minutes to see if the pressure drops. If the pressure holds (thats a thumbs up) there is no leaks within the system. If it leaks you can break down the system to precisely find the leak location and where a drainage repair can be made.

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.

WHAT IF THE AIR TEST FAILS?

A failure of an air test in not sufficIent reason to condemn a pipeline. When this occurs we then proceed with a water test to detect the problem.
