Do I Have A Leak?

Who’s responsible?

As a South West Water customer, you are responsible for any water leak, underground leak or burst pipe on your water supply from the boundary of your property to the property itself (see diagram below). If you are on a shared supply, all homeowners are responsible jointly from the boundary with public land for any common supply pipe, and individually for a branch pipe bringing the water in to your home.


Possible indicators of a leak

  • High water bill, higher than usual, for no apparent reason
  • A damp patch in the garden, on the driveway or anywhere on your land during dry weather
  • The sound of running water when no water is being used
  • An area of lawn which is always green, even when the rest is not

How can I check if I have a leak?

Shut off everything in the house that will be using water, especially taps, but also washing machines, dishwashers etc. Make sure that nothing in the house is on that will require water to function.

If you have one, turn off the rising main, which is usually the internal stop tap located under the kitchen sink or in the downstairs toilet/bathroom, making sure that you have turned it off completely and no water is still coming through to the taps.

Check that the cold water cistern is not filling.

Go to the meter, lift the lid and check to see if the numbered dials are turning. If they are, then you have a leak on your external water supply between the meter and the internal stop tap. If the leak is very small it may not be immediately noticeable if there is movement on the dials, so wait for a few minutes to check.

If you cannot turn off the internal stop tap then turn off all appliances, make sure that no water is going into cisterns or storage tanks and take a meter reading. Wait for about an hour and then take another. If the meter has moved it may mean you have a leak on your external water supply.

I am sending my huge thanks for the finding and repair of a water leak that has been a tremendous anxiety to me for 6 weeks. During this time 6 other gentlemen have been and not one discovered the location of the leak. All this time of course impacting on the accommodation in which lives my disabled son. Ian found it and Matt concurred. I could not be more pleased with the work or the quiet respectful manner they conducted themselves and just got on with the repair. Thank you and I would be glad if you would commend them highly.
