Where is your cistern leaking?
A leaking cistern can leak in a few places, and the spot tells you the cause:
- Inside the cistern, constantly running into the bowl, usually a worn flush or fill valve
- Between the cistern and pan, a worn seal or connector
- From the water inlet, a worn washer or loose fitting
- From a crack in the cistern itself
Most of these are quick, affordable repairs; a cracked cistern needs replacing.
Why a leaking cistern wastes money
A cistern that constantly runs or refills can waste thousands of litres of water a year, which adds up on your bill. A slow leak between the cistern and pan can also damage the wall or floor over time. Because the parts are cheap and the fix is fast, repairing a leaking cistern early is one of the most cost-effective plumbing jobs you can do.
Repair or replace the cistern
Most leaking cisterns are fixed by replacing the flush valve, fill valve, washer or seal, which our plumber can usually do in one visit. If the cistern is cracked or very old and parts are hard to find, replacing the cistern (or the whole toilet) is the better value. We will tell you which makes sense and price both.

Leaking cistern FAQs
Why does my cistern keep running?
Usually a worn flush valve or fill valve inside the cistern. It wastes water and is a quick, affordable repair.
Why is water leaking between my cistern and toilet?
That points to a worn doughnut seal or connector between the cistern and pan. We replace the seal to stop the leak.

A valve or seal replacement is affordable. A cracked cistern needs replacing, which costs more. We quote upfront.

No, a cracked cistern cannot be reliably sealed and should be replaced. We can supply and fit a new one.
How much water does a running cistern waste?
A constantly running cistern can waste thousands of litres a year, noticeably increasing your water bill.
Can I fix a leaking cistern myself?
