Leaky loos

Water trickling down the back of the toilet pan can be silent and hard to spot, so it’s common for leaking toilets to go unnoticed. Here's how you can check your loo.

How much could a leaking toilet cost you?

A leaking toilet can waste around 200 to 400 litres of water a day, which is equivalent to flushing 50 to 100 times.

If you’re on a meter, this could increase your yearly water bill by around £50 a month, so it’s important to get a leaking toilet fixed as soon as possible to save water and money.

How to spot a leak in your toilet

Follow these steps to find out if you have a leaky loo:

1. Flush your toilet

Flush your toilet and then leave it for 15 to 30 minutes.

2. Dry the pan

Dry the back of the toilet pan with a piece of toilet paper.

3. Apply strip or paper

Apply a Leaky Loo strip or piece of toilet paper to the back of the pan and then wash your hands.

4. Leave

Leave your toilet alone for three to four hours and then check back later.

Do you have a leak?

If the Leaky Loo strip or piece of paper remained dry, you don’t have a leak.

If the Leaky Loo strip has changed in colour or the piece of paper has become wet, you most likely have a leak.

What should you do if you find a leak?

If you’ve got a leak, it’s often caused by the flush or fill valve, which can be fixed relatively easily if you are confident when it comes to DIY. If not, we recommend contacted a WaterSafe approved plumber.
