Expert Hydrostatic Pressure Testing in New Braunfels, TX

Hydrostatic pressure testing is one of the most reliable ways to find hidden leaks in your underground plumbing. At Owens Plumbing Services LLC, we use this method to check whether your drain and sewer lines hold pressure the way they should. We plug the main sewer line, fill the system with water to slab level, and watch for any drop in water level. A drop tells us a leak is present. We then isolate sections to find exactly where the problem is. New Braunfels sits on a mix of expansive clay soil and Hill Country limestone. That soil shifts with every rain cycle and dry spell, putting steady stress on pipes buried beneath slab foundations. Homes built between 1980 and 2010 are especially common candidates for this test, as aging pipes in clay-heavy soil are prone to pinhole leaks and joint separation. Whether you are buying a home, dealing with a rising water bill, or preparing for foundation work, a hydrostatic pressure test gives you a clear, factual picture of your plumbing's condition. Call Owens Plumbing Services LLC to schedule your test in New Braunfels.

Hydrostatic Pressure Testing FAQ

Common questions about hydrostatic pressure testing in New Braunfels, TX.

A hydrostatic pressure test makes sense if your water bill has gone up without explanation, you hear water running when nothing is on, or you notice warm spots on your floor. New Braunfels homes on clay soil are especially prone to under-slab pipe stress from seasonal ground movement.

It is not always required, but many buyers in New Braunfels request one before closing to confirm the sewer and drain lines are leak-free. It gives both parties a factual record of the plumbing's condition at the time of sale.

We can isolate and test individual sections of your plumbing system in New Braunfels. Isolation testing helps us pinpoint exactly which line or zone is losing pressure without disturbing the rest of your system.

No, the test uses water at a controlled level and does not apply force that would harm sound pipes. It is a non-destructive diagnostic method used by licensed plumbers throughout New Braunfels and the surrounding area.

We document the findings and tell you exactly where the pressure loss occurred. From there, we can discuss repair options suited to your home's layout and soil conditions.

Homes built between 1980 and 2010 in New Braunfels face higher risk because aging pipes in clay-heavy soil are more likely to develop cracks or joint separation over time. Newer construction can also benefit from a test if foundation movement or drainage issues have been observed.

Excellent service! Mr. Owens installed a water softener, at a reasonable price, in a quick and timely manner. Excellent communication and checked in the day before our appointment. I highly recommend his plumbing services in an area with saturated (haha) with some not-so-great companies (New Braunfels, TX.). Will definitely be calling him again!

Larry Owens did a fantastic job installing my new pot filler. He was on time, professional, gave an accurate quote and cleaned up. He also added an extra water line to a spare refrigerator ice maker. We are so happy and would highly recommended him!
