Spotting a toilet leak isn’t always easy as water often escapes invisibly down the back of the pan, but you could be wasting 400 litres of water per day.
Detecting and fixing a leak in your loo could save you money, if you’re on a meter, and it means less water is taken from the environment to supply your home.
How to spot a leaky loo
Step 1 - Wait until 30 minutes after the last flush and wipe the back of the pan dry with toilet paper.
Step 2 - Place a new, dry sheet of toilet paper across the back of the pan and leave it overnight.
Step 3 - Check your toilet in the morning. If the paper is wet or torn you probably have a leaky loo.
Alternatively, you can use a LeakyLoo strip which is available for free in our water saving pack.
If you’ve got a leak, it’s often caused by the flush valve or fill valve, which can be fixed relatively easily if you are confident when it comes to DIY. If not, we recommend contacting a WaterSafe approved plumber. Visit WaterSafe or call 0333 207 9030 (Monday to Thursday, 8.30am to 5pm; Friday, 8.30am to 4.30pm).
