Under Floor Heating Leak

Central heating leak detection

Do you have underfloor heating? Are you losing pressure on your central heating system. It may be a leak on the under floor heating that is causing the loss of pressure on the heating system.

What can you do to find out if the leak is in the underfloor heating?

Under floor heating systems can usually be isolated from the main system heating system. To check if the under floor heating is leaking isolate the manifold from the rest of your property’s heating system and monitor the pressure. If there is no pressure loss, then the leak is on the under floor heating. Open the isolation valves and check the pressure drops, it is always worth repeating the process a few time to confirm the leak is on the under floor heating. We recommend this is done by a competent person.  If your heating engineer is able to isolate each heating loop in turn you may be able to narrow down exactly which one is causing the pressure loss before we come so we can start detecting the leak in the right zone straight away.

Leave the underfloor heating isolated and give The Leak Team a Call on 0330 102 5572 We will use thermal imaging, ground microphones or trace gas to pinpoint the location of your leak.


The Leak Team can find your leak. Call for a chat on 0330 102 5572 We will give you all the free advice we can.

As well as causing damage at the point of the leak, an undetected leak can also lead to long term damage to your heating system as it’s rust inhibitor will be diluted each time you top up the pressure. Rust particles in the system can damage the boiler and rusted radiators and pipes will eventually need replacing.

Locating the point of the leak will mean no more topping up and will keep your rust inhibitor in the system.

We use Thermal imaging initially to locate the route of your hidden central heating pipes. We can then use our other equipment such as our Ground Source microphone, Gas Trace detector and Moisture meter, along with the Thermal imaging camera to locate the exact source of the leak.

Did you know most household insurance policies offer cover for leak detection under “Trace and Access”? Please check your policy for details. We have many year experiences of working with insurance companies and can provide full photographic reports for insurers or loss adjusters if required.

The Leak Team use the latest methods and equipment to offer a full Trace and Access service. This means that we both locate the source of the leak, and where appropriate, expose the pipework to allow a repair to be undertaken.

We do not necessarily carry out the repair ourselves, but can discuss the next course of action with your plumber.

Our methods include:
Thermal Imaging Camera 
Sound Detection
Gas Detection
Pressure Testing
Endoscope Camera
Moisture Meters
Pipe Detector

Water Analysis using Salt & pH Kit
