Water Pipe Detection

Locating Underground Water Pipes When the exact route of a buried water pipe is unknown, we can determine its position using a signal probe and detector. The probe is inserted into the pipeline, and the detector identifies both the location and depth of the pipe. In cases where the water main is not marked on topographical plans and no precise GPS coordinates are available, the line can still be found using a tracer probe and detection equipment or a pipe microphone. This significantly simplifies the process of accurately locating any water leaks later on.
Description

Can plastic pipes be located if a probe cannot be used?

Yes.
For outdoor pipe tracing, we use a signal probe connected to a low-voltage generator. The generator sends a signal through the pipe, and with a detection receiver, we can accurately trace its route and depth underground.

If the use of a probe is not possible, we apply the acoustic detection method with a ground microphone (often referred to as a “thumper”). This allows us to locate the approximate direction of the pipe based on sound vibrations through the soil. However, this method cannot determine depth and is mainly suited for external pipe networks.

Inside buildings, we use a different type of signal probe designed for short-range detection. In these cases, the measurable depth is limited to about 10–15 cm, which is suitable for locating pipes within walls or floor structures.
