Leak Detection / Repair of Underground Water Leaks


A leak in a water line can skyrocket your water bill. If you’ve experienced an unusually high water bill, you may have a concealed leak. There are two culprits that can also contribute to a high water bill that are not associated with an underground leak. We ask that you check all toilets to be sure they aren’t continually running and also the T and P (temperature and pressure) release valve on the water heater to ensure it is not stuck in the open position. These valves generally discharge at the side or back of your home. These are two common issues that are easily overlooked by homeowners. If you’ve checked these and there aren’t any issues, chances are you have an underground leak.


At Cox Plumbing and leak detection, we apply nearly 30 years of leak detection experience to our customers. We use our state of the art technology to determine the exact source of your leak. This is done with no destruction to your property and is backed by an ironclad guarantee. Don’t forget, all standard water lines should NOT be billed hourly. A guaranteed price is the way to go. With Cox Plumbing & Leak detection, it doesn’t matter if the detection takes 30 minutes or 30 hours, the price is always the same.
