Hydrostatic Testing

Houston Hydrostatic Testing

Whether you currently own your home or are looking to buy one, the experts at Church Foundation Repair recommend testing the sewer lines.

What is the hydrostatic testing process?

A hydrostatic test is performed to determine if an under slab drain line leaks.  Our licensed technicians pull a toilet on the first floor in order to place a monitor in the line to observe the testing process.  The drain line is then blocked (typically at the clean out) with an inflatable test ball. The sewer lines are then filled with clean water and monitored for a period of 20 to 30 minutes. If the water level drops this indicates a leak somewhere in the system and a need to perform an isolation test. If the water level remains the same, the system has passed the test.

What is the isolation testing process?

Isolation testing is performed when a leak is known to be present. Church Foundation Repair uses isolation testing to identify all leaking areas within the sewer system. Isolation testing is similar to hydrostatic testing but on a smaller scale. Our seasoned technicians test small sections of the sewer lines to pinpoint the exact problem areas. One (or more) test balls are placed within the system in order to test small sections at a time and then monitored.

What about the toilets you remove?

All of our testing packages require us to remove a toilet for the procedure. Because of this, our testing packages include re-setting the toilet with new wax seals, caps, bolts, and re-sealing.
