Non-Invasive Detection
We Detect & Repair Leaks in Austin, Dallas, San Antonio & Waco
Did you come home after a long night out and notice a leak? Most people only call a plumber once a leak is creating visible damage. However, our customers more commonly deal with small leaks that can go unnoticed. Small leaks can possibly cause more damage because they can go undetected for long periods of time. One couple came back from vacation to a $3,000 water bill from an undetected leak! You’ll save yourself a lot of money and stress if you know the signs of a water leak and regularly check your home. At the first sign, hire an experienced plumber to accurately detect the source of the leak to prevent damage.

Common Signs of a Leak
Efficient & Precise Leak Detection
Untreated leaks can cause expensive damage to your home or foundation and allow organic growth into your living spaces. That’s why it is important to call a professional plumber as soon as you suspect a leak. Our experienced plumbers will use state-of-the-art techniques and equipment to pinpoint the exact location of your leak. We will then repair it with the least amount of damage to your home or business.
How does Reliant Plumbing repair leaks?
Leaks From Damaged Sewer Lines
Our expert licensed plumbers are trained in the most up-to-date plumbing technologies that allow us to locate leaks without disrupting your home. We use plumbing cameras in coordination with Goldak leak detection equipment.
The camera runs through your pipes identifying any obstructions as well as breaks in the sewer line and/or bellies. The Goldak equipment helps us by using sonar to find the damaged or leaking lines. The line locators can map the location of gas, water, sewer, and even copper lines running from the house to the city meter.
In Austin, Dallas, Waco, and San Antonio, city code requires homes to be built with tracer wires, which are wires that are buried alongside the pipe. Our line locators can very quickly pick up line locations if your home has tracer wires installed.
Gas and Water Leaks
Many customers contact us after receiving a high water or gas bill and are not sure if they really have a leak. In this scenario, we can perform a pressure test to see if there is a leak anywhere in the home’s plumbing system.
For domestic water lines we first install a pressure gauge on a hose bib to get a baseline pressure reading. Then, we turn off the homeowner shutoff valve and if the pressure drops, we know there is a leak. In fact, we can use a series of pressure tests to isolate the specific line causing the leak.
Unlike water leaks, Gas Leaks are much more dangerous if left unattended for an extended period of time. It is incredibly important to call a Reliant Plumber so we can get your gas shut off and fix the leak.
Leak Detection FAQ
Plumbers use specialized tools such as acoustic sensors, thermal imaging cameras, and camera inspections to locate leaks without unnecessary demolition. These methods allow for fast, accurate detection behind walls, under slabs, or beneath landscaping.
Unexplained increases in your water bill, damp spots on floors or walls, mildew or mold growth, low water pressure, or the sound of running water when all fixtures are off are strong indicators that you may have a leak.
No! If a leak is caused by damaged underground pipes, trenchless repair methods—like cured-in-place lining—can often fix the issue without major digging, preserving your yard, driveway, or building foundation.
Commercial buildings often have larger, more complex plumbing systems with multiple water supply lines, fixtures, and higher usage. Commercial leak detection requires advanced diagnostic tools and strategies to minimize downtime and avoid costly water damage to the business.
Leaks in multi-family buildings can spread damage across multiple units, leading to high repair costs, tenant complaints, and even legal disputes. Early detection helps isolate the problem and prevent water damage from affecting shared walls, ceilings, or foundations.
Most modern leak detection methods are non-invasive and can be done with minimal disruption. Plumbers can often diagnose issues without opening walls or floors, ensuring your property remains functional while problems are investigated.
The cost depends on the property type, plumbing system complexity, and leak location. While commercial and multi-family properties may require more advanced equipment, investing in professional leak detection is usually far less expensive than repairing extensive water damage later.
