How to check for leaks

While Three Valleys Water using the latest technology to search for leaks hidden deep underground on their 14,000 km network of pipes, the best way for you to find a leak is to use your eyes and ears.

If you have a leak on your supply pipe, it is your responsibility (if you are the property owner) to ensure that the leak is repaired promptly. There are a number of simple checks you can do to check whether you have a leak:


	Do you have a damp patch in the garden, driveway, or anywhere on your land during dry weather?
	Do you hear water running down a drain when no water is being used in your property?
	Is one particular patch of the lawn always green no matter how dry the weather has been?
	Can you hear water running down a drain when no water is being used in your property?
	Can you hear water hissing or the sound of running water (rather like when your tank or WC cistern is filling), when there is no water being used in the property?
	If you have a meter, make sure that no water is being used in the property and that all taps are turned off, then simply look at the meter for a couple of minutes. None of the dials should move. If they do then there may be a leak on the supply pipe
	If you have automatic flushing urinals check that they are set properly. They should only flush once every 20 minutes.
