How can I spot a leaky loo?

Leaky loos are one of the most common causes of unexpectedly high water use but aren't easy to spot as the water just dribbles away down the pan.

A single leaky loo can waste up to 400 litres of water a day – the equivalent of five full bathtubs.

How to spot a leaky loo

If you can hear water flowing but the toilet has not been flushed, or if you can see a constant trickle at the back of the toilet pan, you may have a leaky loo.

  • Wait until 30 minutes after the last flush then wipe the back of the pan dry with toilet tissue.
  • Place a new, dry sheet of toilet tissue across the back of the pan. Leave it in place for up to three hours without using the toilet (this may be best to do overnight).
  • If the paper is wet or torn in the morning, you have a leaky loo.

If you do have a leak you may wish to contact an approved plumber.
