Testing if you have a water leak

We own the pipes that run up to the street boundary and we will always repair them as quickly as possible.

Between the street boundary and your internal stop tap is the private supply pipe. Although the pipe belongs to the property owner we will offer a free repair where possible.

All internal pipework and fittings inside the property are the owner’s responsibility to repair.

If you notice a leak or think you have one near your property, please contact us on 0800 052 0130 (24 hours a day, 7 days a week).

Sometimes a private water supply pipe can provide water to several properties, if we find your water pipe is shared we’ll discuss all options on how to repair it with you when we visit. You may be interested in having your own separate water pipe installed, which we would always recommend.

A private supply pipe can be quite long and cross someone else’s property boundary. If your supply pipe runs across your neighbours' boundaries then you are also responsible for this part of the pipe.

We recognise that repairing a leak on the supply pipe serving your property can be costly. This is why, we are keen to support as much as we can.

Where a repair is undertaken by a contractor, we can support with a contribution of up to £150. Should a new supply pipe be required, for example where you chose to come off a shared supply, we can support with a contribution of up to £500 and a free new connection to our main.

This contribution will be made on confirmation by Welsh Water that the supply is free, and we may require evidence of the works, and the costs associated – so keep any invoices or receipts.

As we guide you through the process of resolving your leak, we would be more than happy to talk through the above to make sure we can process a payment quickly upon resolution.
