What Is Hydrostatic Testing?
Hydrostatic Testing in Houston, TX is a simple but powerful way to check if your under-slab sewer lines are leaking. Houston homes are built on concrete slab foundations, which means the sewer pipes run underneath the foundation where you cannot see them. A slow leak under that slab can go unnoticed for months or even years. Our team inserts an inflatable test ball into your main sewer line to seal it off, fills the isolated system with water, and watches the water level closely. If the level holds steady, your lines are in good shape. If the level drops, there is a leak beneath your slab.
You should schedule a hydrostatic test if you smell sewage inside your home, you notice soft spots or cracks in your floors, you are buying or selling a home, or your home is more than 20 years old. Learn more about how hidden sewer leaks affect residential foundations from the Foundation Performance Association, a Houston-based organization dedicated to foundation education for homeowners.
Signs You Need Hydrostatic Testing in Houston
Houston’s clay soils shift constantly with seasonal moisture changes, and that movement puts real stress on the sewer pipes buried beneath your slab. Over time, those pipes crack, corrode, and separate at the joints. The tricky part is that the damage happens underground where you cannot see it. So, your home may be showing you warning signs without you realizing what they mean. Watch for these signs that it is time to schedule a hydrostatic test:
- You smell sewage inside your home but cannot find the source
- You notice soft spots, cracks, or shifting in your flooring
- Wet patches or unusually green grass appear in your yard
- Your drains are slow throughout the entire home
- Your home is more than 20 years old
- You are buying or selling a home in Houston
Any one of these signs is reason enough to call us. The sooner you test, the less damage a hidden leak can do to your home and foundation.
How Our Hydrostatic Testing Process Works
Access the Clean-Out
Our technician locates your main sewer clean-out at your property. This is the access point we use to reach the under-slab drain system. Most Houston homes have a clean-out near the foundation or in the yard.
Insert and Inflate the Test Ball
We insert an inflatable rubber test ball into the main sewer line at the point where it exits the slab. We inflate it to create a sealed blockage that fully isolates the under-slab portion of your drain system.
Fill the System with Water
We fill the isolated section of pipe with water until it reaches the level of the lowest drain inside your home. This fully charges the entire under-slab system and prepares it for monitoring.
Monitor the Water Level
We closely watch the water level for a set period of time. A steady level means your under-slab sewer lines are intact and leak-free. A dropping level confirms that a leak exists somewhere beneath your slab.
Results and Next Steps
We walk you through the results immediately on site. If no leak is found, you receive a written record and peace of mind. If a leak is detected, we recommend a sewer camera inspection to pinpoint the exact location before we recommend the right repair solution.
What Happens If We Find a Leak?
A positive hydrostatic test result means water is escaping somewhere beneath your slab. That does not automatically mean you need a full sewer replacement. The repair needed depends on the size and location of the damage. Repipe Solutions Inc. handles the complete repair process so you never need to call a second company.
We always start with a sewer camera inspection to pinpoint exactly where the problem is. Then we recommend the most appropriate repair option from the solutions below.

Spot Repair
If the damage is limited to one small section of pipe, a targeted spot repair is the fastest and most affordable fix. We open only the area we need and leave the rest of your system untouched.

Hydrostatic Testing for Houston Home Buyers and Sellers
Standard home inspections do not include under-slab sewer testing. That means Houston buyers regularly close on homes with hidden slab leaks and discover the problem only after they move in, when the cost falls entirely on them. A pre-purchase hydrostatic test changes that completely.
For buyers: A hydrostatic test gives you the facts before you sign. If a leak is found, you can negotiate repairs into the deal, request a price reduction, or walk away with full confidence. If the test is clean, you close knowing the sewer system beneath the slab is solid. It is one of the smartest investments you can make before purchasing a Houston home.
For sellers: A completed hydrostatic test report is a powerful trust signal that removes one of the most common objections in Houston real estate transactions. Buyers and their agents feel more confident moving forward when the seller has already addressed slab sewer health. It speeds up the closing process and protects your sale price.
For realtors: Recommending a hydrostatic test to your clients before listing or before closing is a simple way to protect the transaction and your reputation. Repipe Solutions Inc. works with Houston-area real estate professionals to schedule fast, professional tests that fit your closing timeline. Call (832) 662-4288 to discuss scheduling for your next transaction.
How Much Does a Hydrostatic Test Cost in Houston?
Hydrostatic testing in Houston is one of the most affordable diagnostic services available given what it can reveal. The cost of a single test is a fraction of what an undetected under-slab leak can ultimately cost in foundation repairs, water damage, and emergency sewer replacement.
The exact price depends on a few factors specific to your property:
The size of your home and the total length of your under-slab sewer system
Accessibility of your main sewer clean-out and how easily our team can reach it on your property
Whether a follow-up sewer camera inspection is needed after a positive test result to pinpoint the exact leak location

Frequently Asked Questions
How long does a hydrostatic test take?
Does the hydrostatic test damage my pipes?
No. The test fills your existing sewer lines with water at normal pressure levels. It does not stress or damage pipes that are in good condition. The inflatable test ball is inserted and removed without any cutting or excavation.
Can I stay home during a hydrostatic test?
Yes. The hydrostatic test is completely non-invasive. You do not need to vacate the property. Our team works quickly and cleanly with minimal disruption to your home and your day.
Is a hydrostatic test the same as a sewer camera inspection?
No. They serve different purposes and work best together. A hydrostatic test tells you whether a leak exists beneath your slab. A sewer camera inspection shows you exactly where the damage is located and what condition the pipe is in. When a hydrostatic test comes back positive, a camera inspection is always the recommended next step.
What if my hydrostatic test comes back negative?
How often should I schedule a hydrostatic test?
For homes over 20 years old we recommend testing every 3 to 5 years as a preventative measure. You should also test any time you notice warning signs or before buying or selling a property in Houston.
