What is Hydrostatic Pressure Testing?
Hydrostatic testing, also known as hydrostatic pressure testing, hydro testing, or leak testing, is a method used to assess residential and commercial sewer line systems for water flow and detect any hidden leaks.
An inflatable testing device is inserted into the pipe to create a controlled blockage. We then track the flow and water level changes in the sewer line to locate potential leaks—especially those that may be hidden beneath your slab.

What Are the Benefits of Hydrostatic Leak Testing?
Since main sewer lines are buried underground, spotting leaks can be tough. Often, leaks can go unnoticed for months or even years, leading to significant damage and costly repairs by the time they surface.
Even a small leak can attract tree roots, which grow into the pipe system, expand the damage, and eventually break the pipes. Hydrostatic pressure testing helps you catch these issues early—before they become expensive repairs.
It’s smart to schedule a hydrostatic test when moving into a new home to catch any hidden faults. Regular testing is also recommended based on the age of your home and time since your last inspection. If you’re unsure whether it’s time for a test, feel free to reach out to our expert team for guidance.
Hydrostatic Pressure Testing Procedure
The hydrostatic testing process includes the following steps:
Insert the inflatable testing device into the pipe system.
Inflate the device to create a temporary blockage.
Monitor water levels to determine if a leak is present.
If water levels drop, a leak has been detected; if they remain steady, the system is secure.
Once a leak is confirmed, our specialists will locate the issue and recommend a suitable repair method.
