What Is Static Testing?
This test is usually confined to your drainage system and is required when you have foundation repair issues. It is a process where the drains are capped on one end and then filled with water to floor level. The test is called static because the water remains stationary or (static) with no additional pressure being applied.
Normally, it is performed by placing a test ball in the upstream side of the cleanout of the main drain outside and then removing a toilet where the water will be added and monitored for 15 minutes. A drop in water level would indicate a failed test at which point we would suggest a camera inspection and further testing and isolation.
