Pipe Locating and Mapping for Tampa, Brandon, Citrus Park, Westchase & Throughout Hillsborough County

The plumbing pipes in your home are conveniently hidden away underground or in your walls and ceilings. That’s a good thing, except when you want to add an extra outside faucet or are thinking about remodeling and want to know if a pipe is nearby. Often, knowing the exact location of the pipes is the first step in diagnosing a problem, which is where Grable Plumbing comes in with our state-of-the-art pipe locating and mapping technology.

In the past, hidden pipes were found using the “best guess” method, often resulting in needless destruction to the home and a lot of wasted time. Today, we use a wide variety of pipe locator technologies to find hidden pipes such as ground-penetrating radar, radiodetection, infrared and X-rays.

You can count on Grable Plumbing for quality work, great warranties, and, of course, our Peace of Mind Guarantee. In addition to pipe locating, we also offer video sewer and drain inspection, trenchless pipe replacement, and many other services using innovative plumbing technology.


Radiodetection is a method of locating pipes by inducing a radio signal into the subject pipe. This is done by either directly contacting the pipe with a transmitter or by an indirect induction method via a broadcast coil mounted on the surface. Once the signal is induced into the pipe, we are then able to map the pipe’s path with a hand-held receiving antenna on the surface.

This is a quick and efficient way to locate metal pipes hidden underground or in walls.

For non-metal pipes we place a small radio-transmitting probe into the pipe and follow along topside with the receiver as the probe is pulled, pushed or flushed down the pipeline.

Ground-Penetrating Radar

Ground-penetrating radar (GPR) will locate pipes below the surface, under reinforced concrete, through reinforced concrete walls, and under asphalt and sidewalks. GPR works in a fast and reliable manner. It is also very safe, as it uses no radiation. It is often used to augment our other locating techniques.

A unique feature of the radar is that under some conditions, it can locate trenches where lines were buried as well as old building foundations and abandoned storage tanks.
