Radiodetection RD500 Plastic Water Pipe Locator

The RD500 is a specialised instrument for locating and tracing buried plastic and/or concrete water pipes.

The biggest challenge in the water industry today is leakage, the costs involved and damage to the environment.

The RD500 plastic water pipe locator from Radiodetection can help solve this problem.

It traces plastic water pipes over distances up to 150m and is quick and easy to use. Operators can learn to locate and trace using the RD500 in just a few minutes.

Conventional Pipe and Cable locators trace electromagnetic signals travelling on metal pipes and cables. Those signals don’t travel on plastic. The RD500 however generates acoustic signals, which travel down the plastic pipes as vibrations. The RD500 locator detects the vibrations: the nearer to the pipe, the louder the vibrations are, and therefore an operator can identify the location of the buried pipe and trace its route.

The RD500 works best when combined with Pulse Transmitters.

There are two different types of Pulse Transmitters available:

  • Water pressure powered mechanical Pulse Transmitter
  • RD500 Tx Electronic Pulse Transmitter

The RD500 Tx is the better performing transmitter.
It is an
electronic transmitter that provides a traceable pulse down a plastic water pipe via its custom Pulse Transmitter fitting. The RD500-Tx is ideal for use in low pressure water supplies such as sprinklers, hoses or domestic supplies where push fittings may be part of the infrastructure. The advantage of using the R500-Tx is that once connected, it requires no manual adjustment of the water pressure to provide a traceable signal thus speeding up location and tracing services.


Founded in 1970, Radiodetection, headquartered in Bristol, United Kingdom, is a highly recognised global brand and market leader in the Utility locating and cable avoidance sector. Manufacturer of the instantly recognisable CAT & Genny as well as the advanced RD7100 and 8100 cable locators, Radiodetection's cable test products quickly locate problems such as breaks or deteriorating insulation.
