Hydrostatic pressure testing is a specialized diagnostic method used to identify hidden plumbing leaks in a home’s sewer or drain system. Often employed after signs of foundation movement, unexplained water bills, or during real estate transactions, this testing method ensures that a property’s plumbing infrastructure is watertight and structurally sound. Metroplex Leak & Line Locators offers expert hydrostatic testing services to foundation companies and plumbing companies, helping homeowners and real estate professionals detect and address hidden issues before they escalate.
Whether you are a homeowner concerned about potential leaks or a real estate agent involved in property inspections, understanding how hydrostatic testing works can be vital for protecting your investment.
What Is Hydrostatic Pressure Testing?
Hydrostatic pressure testing involves sealing off sections of a plumbing or sewer system and filling them with water to monitor for leaks. The system is observed under pressure for a specific time frame. If the water level drops, it indicates a leak within the tested area.
This method is highly accurate in detecting:
- Concrete Slab leaks
- Broken underground sewer lines
- Plumbing joint failures
- Hairline cracks in cast iron or PVC pipes
Why Is Hydrostatic Testing Used?
Leak Detection in Hidden Areas
Unlike visible plumbing leaks, slab and subsurface leaks can go undetected for months. Hydrostatic testing allows professionals to isolate and test these areas without invasive procedures, making it ideal for:
- Homes built on concrete slabs
- Older homes with cast iron drain lines and sewer pipes
- Homes with shifting foundations or soil movement
Real Estate Inspections
Real estate agents recommend hydrostatic pressure testing during home inspections, particularly in older homes or properties with signs of drainage issues. It provides added transparency for buyers and helps sellers address issues proactively.
Foundation and Structural Integrity
Leaks beneath a home’s foundation can cause moisture buildup, soil erosion, and even structural damage. Hydrostatic testing is often one of the first steps in diagnosing unexplained foundation movement.
This non-invasive process avoids immediate excavation and helps determine the location and severity of leaks before recommending repairs.

Compared to digging or breaking through slabs unnecessarily, hydrostatic testing leverages modern technology to help avoid unexpected plumbing repairs.
When Should You Consider Hydrostatic Testing?
Consider hydrostatic testing if:
- You notice damp spots on flooring or around the foundation
- There is an unexplained spike in water bills
- The home has had previous foundation repairs
- You are purchasing or selling a home, especially one over 20 years old
- Plumbing issues have been persistent without visible leaks
