Water leaks inside a property can be very tricky to find and if left unattended they can cause devastating water damage to your home or commercial property. That is why National Home Repairs’ leak detection service aims to find your water leak before your property suffers substantial water damage, saving you both time and money.

Below we have also provided a few useful tips that could help you to detect a water leak. Be sure to find your water leak as soon as you can. Remember that some insurance companies may dispute an insurance claim for any water damage caused if they feel you have not acted quickly enough. This is known as a “secondary damage clause”.

Is the leak inside or outside?

If you believe the leak may be outside your property, one of the first places to check to find a leak, is yours and your neighbours’ water mains supply. You can contact your water supplier directly and ask them to check yours and your neighbours’ mains supply. Your water supplier can perform a test to determine where the water is coming from – be it ground water, mains water or sewage. This can narrow down your search for the source of the water. See the Water UK’s website to find your local supplier.

Drop in boiler pressure

One of the most common indicators of a water leak is an unexpected drop in boiler pressure. If you regularly experience low boiler pressure, call our leak detection team as soon as you can on 0333 772 1956.

Check devices, fixtures and fittings

• Check to see if taps are constantly running or dripping. Unsure if a tap has a water leak? Put the plug in a dry sink or bath, leave the tap for a few hours and see if any water has collected.
• Check that all water using devices, such as toilets, urinals and ball valves are working correctly and are properly sealed. Cisterns malfunctions could cause your toilet to constantly flush.
• Have any outside taps been left running or have they been vandalised?

Check your appliances

An escape of water is very common from plumbed in appliances such as washing machines, dishwashers, showers, bathtubs and toilets. A water leak could be the result of a broken valve or a blockage in fittings or appliances.

Central heating

If water is appearing under your floors or carpets you may want to check your central heating, as this may be the source of the water leak. Check your pipes and radiators, with the pipes that run under the area of damp floor being your first port of call.

You can also ask a National Home Repairs to perform a pressure test, which may help to trace where in the system a leak is coming from.
