GEOTHERMAL SYSTEM LEAK DETECTION

---

Geothermal heating and cooling systems rely on closed-loop piping buried beneath the ground to circulate fluid between the earth and the building. When that underground piping develops a leak, the system may lose pressure or fluid, operate less efficiently and become increasingly costly to run.

Because geothermal loops are buried and difficult to access, locating a leak requires specialized equipment and expertise. Mainline Leak Detection uses specialized acoustic and tracer gas technology to pinpoint leaks in underground geothermal piping serving residential, commercial and governmental properties.

Signs of a Possible Geothermal Loop Leak

• Repeated loss of system pressure
• Unexplained loss of fluid from the system
• Reduced heating or cooling performance
• Increasing energy or operating costs
• Wet or unusually saturated areas above buried loop fields

How We Locate Geothermal Leaks

Depending on the system and conditions, we use specialized acoustic equipment to detect the sound created by escaping fluid or introduce tracer gas that can be detected at the leak location.

Pinpointing the problem before excavation begins allows your geothermal contractor to focus the repair where it's actually needed—reducing unnecessary digging, property disruption and guesswork.
