Here at ADI Leak Detection we are proud to be market leaders in water leak detection services – not just in London but right across the UK.

We were contacted by a customer in South London, who suspected that they had a leak on their external water mains due to an unexpected very high water bill – after carrying out a simple water leak test using the water meter they called us.

In this instance it was clear that the responsibility for the water leak fell with the owner of the property as the location of the leak was on his property. We often get ask who’s responsibility is a water leak? The short answer is that if it is on your property then you as the home/landowner. If the leak is before the water meter and off your property then responsibility lays with the water board. Don’t panic though as your home or buildings insurance may cover you for the cost of tracing and accessing the leak, as long as you have Trace and Access cover on your policy.

Lets take a look at what our engineers found on the leak detection job.

Before We Found The Water Leak

After We Fixed The Water Leak

It’s not always possible, but it gives us a great sense of satisfaction when we are able to find a leak, access it, replace a whole section of pipework, backfill, AND reinstate the ground surface in a single day!

All this was achieved by just one Engineer on his own.  He goes by the name of Vince and he is our external mains specialist.

After detecting the leak using tracer gases, the area next to the flower bed was exposed to find a leak on an old lead supply pipe.

The Leak & The Repair!

Replaced With MDPE Water Main

ADI Leak Detection To The Rescue Again…

Lead has not been used in the installation of water supply pipes since the 1970s, as it’s now known that lead exposure can pose significant health risks, particularly to children and pregnant women.

It can also become brittle and weak over time, so Vince replaced a whole section with 25mm blue plastic MDPE – which is much better for your health and much longer lasting too!

Looking at the ‘After’ picture, would you have even guessed we’d been there to find and fix a leak? We think it’s safe to say that Vince earnt his money that day!

This customer was lucky that Leak Detection Engineer Vince was able to resolve the problem on the lead pipework in one day. Sometimes old lead supplies are found to be in such bad condition that they cannot be repaired, because new leaks will just keep springing up at other weak spots along the pipe run.

Fortunately, we also carry out trenchless water mains replacements using pipe pulling and moling – so you can be sure that our specialist team have the solution for you.
