How to check your outside water pipe for leaks

If your meter is OUTSIDE your home / business (for example, in a chamber in the footpath or in your garden) then there is a chance the leak may be on your water supply pipe. This is the underground pipe that delivers water into your home from our water main in the street. For more information on water supply pipes, click here.

Before checking your water supply pipe for leaks, we would always recommend checking inside your home / business first. That's because the majority of leaks can be found on toilets, taps, showers, poorly plumbed appliances and faulty cistern overflows. The most common cause of leaks are leaky loos, you can find further details here.

How to check if your water supply pipe has a leak

  1. Turn off your internal stop tap. You can normally find this under a kitchen sink or in a downstairs loo. See our videos for more information on finding and operating your stop tap.
  2. Go outside and take a meter reading (Click here to find how to take a reading or if you're having trouble locating your meter).
  3. Wait for one hour.
  4. Take another meter reading.
  5. If there is no difference in the two readings then the leak is somewhere inside your home / business. However, if there is a difference between the two meter readings then it’s likely the underground water pipe has a leak.
