Toilet keeps running in Box? Here's what to do.
A constantly-running toilet wastes 200+ litres of water a day and will eventually push your bill up if you're metered. The fix is one of two parts inside the cistern.
Try this first
Safe steps you can take in the next 10 minutes — in order.
- 1Lift the cistern lid and watch — see whether water is leaking past the flush valve or constantly coming in via the float valve.
- 2Replace the flush valve seal (£8, 20 minutes) if water is bypassing it.
- 3Replace the float valve (£15, 30 minutes) if water is constantly filling.
- 4Descale the flush valve seat with white vinegar and a cloth.
When to stop and call
If you've tried both fixes and the issue continues, the cistern itself may be cracked. Time for a new WC.
Likely causes
Most cases of a toilet that keeps running in Box homes come down to one of these.
- Failed flush valve seal at the bottom of the cistern
- Failed float valve allowing constant fill
- Limescale on the flush valve seat
