Is your toilet leaking? Fix it for free with Dŵr Cymru

We’ve teamed up with Dŵr Cymru to help you save water and money.

Bathroom with toilet, sink, and mirror

Did you know a leaky toilet can waste up to 215 litres of water every single day? That’s enough to fill nearly three bathtubs, and could be costing you hundreds of pounds a year!

Why fixing a leaky toilet matters 

Even though Wales is one of the wetter parts of the UK, water is still a precious resource. Every drop counts. A constantly running toilet, whether it’s a small trickle or a steady stream, can add up fast. 

Leaky loos are one of the most common culprits for water waste in homes. If you’ve noticed your toilet running when it shouldn’t, you might have a leak. 

How to check for a leaky toilet

  • Can you hear water running in your toilet when it hasn’t been flushed? 

  • Do you see a small stream or trickle in the bowl? 

  • Has your water bill gone up unexpectedly? 

If you answered yes to any of these, it’s time to take action. 

Get it fixed – for free!

Small fix, big impact

Fixing a leaky toilet might seem like a small thing, but it’s a big step toward reducing water waste, saving money and cutting carbon emissions.
