Experts In Water Leak Detection On Water Mains

Water mains leaks normally are normally external under your driveway, pathways or gardens.

The water main brings water into your house from the mains out on the street and the water main on you property is your responsibility to maintain, repair and replace as required. If the water leak is over your boundary then you will need to find and repair the leak. 

Water mains leaks can also occur inside a property before teh stopcock – which is usually located internally on an external wall of a property, but could be positioned anywhere in any location!

A water mains leak would mean a continual water leak as the main is never closed off, like a tap.

Water mains leak detection is a very specialist service, carried out only by specialist leak detection companies. Your average contractor does not have the tool set or skillset to trace the source of the leak without simply digging up meters and meters of your property.

There are many different leak detection methods that are non invasive, we utilize as many of them as needed in order to trace the source of your water mains leak, or leaks as the case may be!

Equipment We Use To Find Water Leaks During Your Leak Detection Service

  1. CAT & Genny – This helps to map where the water mains pipe runs under the ground.
  2. Acoustic Microphone – This is a highly sensitive microphone that is used to listen to any noise on the water mains pipe. A water leak will be creating a vibration and this equipment allows us to hear it up to 3 meters below the surface!
  3. Tracer Gases – Through gas tracing, inert tracer gas is added to the pipes under high pressure. The technicians then use a sensitive probe to know where the tracer gas is escaping at ground level.

Once our water mains leak detection team has identified the leak location, they can repair the leaking water mains.Often the repair can be carried out on the same day by the team.

If the repair is carried out on the same day we re-test the water mains for any further leaks.

Our leak detection engineers are only assigned one leak detection per day, meaning they are devoted to finding and repairing your leak on the same day if physically possible!
