Below we describe septic tank locating tools & equipment. If you have not read our more basic guide to finding your way to the septic tank by visual inspection, see SEPTIC TANK, HOW TO FIND.

Watch out: do not try to probe or excavate a septic tank, drywell, or cesspool if you are not certain that the installation has a save, secure cover. Probing or digging over a failing septic tank or cesspool or drywall can precipitate a fatal cave-in of the system.

Warning about using metal detectors or electronic pipe sensors to find Septic Tanks

Metal detectors or probes which mark the path of an underground pipe are excellent and rapid ways to locate buried drain and septic system components. But at an old property we've had an occasional glitch that was potentially dangerous. Older properties sometimes have multiple generations of buried wires and pipes which can lead to an error in the readings from buried pipe or buried septic tank sensors.

We called our local gas company to locate a buried gas line. Clipping a sending unit to a pipe at the gas meter the technician proceeded to paint a yellow line across our (then frozen) soil. He said that his yellow mark was accurate to an inch in marking the exact pipe location.

Using a jackhammer to break frozen soil to locate a water pipe we began digging 18" away from the yellow line marking the gas line. As you might guess, we found the gas line itself right where we were digging! Further investigation found that an old steel water pipe running parallel to the current and parallel to the gas line had caused an 18" error in the readings from the buried pipe sensing equipment.

Watch out: Do not use backhoes, wrecking bars, or jackhammers to excavate where dangerous utilities may be buried. If you call your local gas or electric utility company they will be glad to send an expert to your site to mark the location of buried electrical and gas lines that may be present.
