Pipe Location Services

At Water Loss Solutions, we have invested in some of the best pipe location equipment in the industry.  Every van is equipped with over £20,000 of Hi-tech equipment to help find service pipes, detect water leaks and find drainage defects.

We will typically use any combination of the following equipment.

  • Signal generators
  • Pipe Knockers
  • Tracer reels and sondes
  • Drainage cameras

Utility Tracing and Pipe Locating are methods used to accurately trace and locate the paths of underground services such as mains water supply pipes, electrical, gas or even drainage systems.

It allows us to collect accurate data which aids us in many ways, such as:

  • Leak detection on an underground supply pipe
  • Locating blockages within a drainage system
  • Locating a hidden septic tank
  • Mapping of field drains
  • Ensure a site is clear of underground service before excavation

There are two different types of underground service pipes, either “conductive” metallic or “non conductive” plastic. At Water Loss Solutions we have invested in high quality German pipe location equipment from Sewerin, allowing us to trace any type of underground services pipes.

Pipe Location Detector



A “signal generator” is connected to a conductive material such as copper pipe with a secondary cable earthed into the ground through an earthing spike.

Once this is connected the “signal generator” sends a pre-selected frequency signal through the line allowing us to track the below ground service with the use of a “Signal Receiver”.

Our quality Sewerin equipment allows us to adjust our signals from 0.01 hz through 200 khz, this gives us the ability to track long distance pipes with high frequencies or short distance at low frequencies.

Being able to trace at low frequencies is an added benefit, with higher frequencies there is a chance of the signals jumping from the one service to another service line thereby risking a false track.

So being able to adjust to a low frequency you can trace a line where there are many services in close proximity.

Signal Generator


The combophone knocker or the “knocker” as we call it is very effective on all non conductive materials like Alkathene or MDPE water supply lines where little access is available.

The knocker is a battery powered unit which straps around the water pipe.

This works like a small piston driving out a metal shaft which knocks against the water pipe which in turn sends out a heartbeat like sound along the pipe.

With the use of our ground microphones we are able to listen for the heartbeat like sound and follow that sound along the presumed pipeline, this allows us to trace the line from point A to Point B with great accuracy.

The glass fibre reel is a highly effective and accurate way of tracing a service line like non conductive mains water supply pipes, drainage or even service ducting from as small as 15mm.

If for example you wanted to trace a water supply pipe, you would remove a section of pipe or perhaps a stopcock and insert the reel into the line.

While one person continues to feed the reel into the line the other person, using the signal receiver unit, is able to track the reel by virtue of the sonde attached to the reel head.

This provides great accuracy in finding the path of the service and its depth.

The CCTV Drain camera is a camera attached to a 70 meter fiber optic reel with a sonde at its head.

This serves a dual purpose within the drainage sector, we able to visually see what is going on below ground and at the same time trace the line of the service pipe.

This provides for great accuracy in locating the pipe defect, digging down and final repairs, all helping to reduce overall costs.

At Water Loss Solutions we deal with a large variety of projects from leak detection through to drainage solutions and system mapping, which is why 90% of our projects require us to know where underground services are running.

Not only does this help us to input the correct data into our leak detection equipment to pinpoint leaks, it also allows us to to eliminate the pointless and aimless digging of expensive holes.in the ground.

This is particularly relevant on expensive coverings such as concrete, tar and monoblock.

With our high-tech equipment, expertise and and knowledge we are able to reduce cost, time and inconvenience.
