Hydrostatic Pressure Testing in DFW

What Is Hydrostatic Pressure Testing?

Hydrostatic pressure testing is the most reliable method for detecting leaks in a home's underground plumbing system. The test involves temporarily plugging the main sewer drain and filling the entire sewer system with water. If the water level drops, there is a confirmed leak somewhere in the drain system beneath the slab.

This test is commonly required during home purchases, insurance claims, and after foundation repairs.

When Is a Hydrostatic Test Needed?

• Home purchase – Many buyers request a hydrostatic test as part of their due diligence
• Foundation repair – Required by many foundation companies before and after repairs
• Insurance claims – Documentation of a leak for homeowner's insurance
• High water bills – When a sewer leak is suspected but not visible
• Post-repair verification – Confirming a repair was successful
