A single leaky loo can waste up to 400 litres of water per day – the equivalent of five full bathtubs - costing up to £300 per year for metered customers.
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, so they often go unnoticed.
This is bad for the environment and, if you have a water meter, this is also bad for your pocket.
How to spot a leaky loo
If you can hear a flow of water when the toilet has not been flushed, or can see a slight but 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.
