Toilet Cistern & Flush Repairs
Toilet Cistern & Flush Repairs
A running toilet can waste hundreds of litres a day and shows up on a metered bill fast. Most are fixed in one visit with a new fill or flush valve.
About this service
Toilet Cistern & Flush Repairs in South West London, done properly the first time
We repair close-coupled, back-to-wall and concealed-cistern toilets: replacing fill valves that won't shut off, flush valves and diaphragms that let water trickle into the pan, worn flush buttons and cracked cistern seals.
Concealed frames behind tiled walls need care — we access through the flush plate wherever possible so nothing has to be broken out. Very common in the newer bathrooms and en-suites we look after across Kingston upon Thames, Putney and Richmond.

Frequently asked
Your questions, answered
Why is my toilet constantly running into the pan?
A worn flush valve seal or a fill valve set too high. Both are inexpensive parts we usually carry with us.
Can you repair a concealed cistern without removing tiles?
In nearly every case yes — modern frames are designed to be serviced through the flush plate aperture.
My flush is weak — is that the cistern?
Often the water level is set too low or the flush valve diaphragm has perished. We check the pan and waste too, in case it's partly blocked.
