Like all GPRs, high conductivity soil, clay reduces the maximum depth that the signal can penetrate. Sandy soil is excellent for ground penetrating radar.

The Radiodetection RD500 locates all clean water pipes including PVC, Plastic, AC without tracer wires.
The RD500 is a patented PVC, plastic pipe locator valve that connects to the water supply pipes and creates 5 psi pulses higher than the pipe pressure. Then locate PVC pipe by listening with the RD547, Stethophon 04, Aquaphon A100 or A200, T10 or other acoustic leak detector for the loudest position.
Water Pulse Generator sends along the pipe which then can be located using the RD542, RD545, RD547, Stethophon or Aquaphon leak detectors.
The "Sewerin Stopper" connects to hydrants to located plastic, PVC and non-metallic water pipes. In good conditions the thumper locates plastic pipes over 1000 feet in each direction. Deeper pipes and softer soils reduce the maximum distance. Both the frequency and intensity of the pressure pulse are controllable.

The Combiphon Generator powers and controls both the Knocker and Stopper PVC pipe locators.

The Knocker connects to the outside of PVC plastic(non-metallic) pipes and taps on the plastic pipe, sending sound pulses down the pipes. The Knocker plastic pipe locator controls both the frequency and intensity of sound pulses, then you find the PVC pipe location with the Stethophon 04, Aquaphon, or RD500 receiver or other acoustic leak detector.
The Knocker works for all pipes in general. A water pressure and flow is not needed. Connecting is quick and easy.
Locate plastic water pipes up to 300 feet and up to 100 psi by inserting the locator traceable rodder using a sealed stuffing box into plastic water pipes for accurate location and depth measurements. The stuffing box connects to the yoke which holds the meter using an adapter.
Available in 100', 150', 200', 250', 300' kits with 3/16" diameter pushrods.
Locate non-metal water pipes and plastic water mains up to 600 feet without a tracer wire. Seals with live water pipes upto 100 psi. Locate the position and depth with Radiodetection locators such the RD7000 Underground Locators or the RD5000 Pipe Locator.
The RD547 includes a mode designed for following the water pulse sounds applied to pipe by the RD350 water pulse generator.
