Running Toilet Repair in Kingston upon Thames
A toilet that trickles into the pan can waste more water than the rest of the house combined and shows up fast on a metered bill. It's nearly always the fill valve or the flush valve seal.
Local engineers, same-day emergency response, fixed prices — from the team based right here in KT1/KT2.
Running Toilet Repair for Kingston upon Thames homes
We test the cistern with dye to confirm whether water is passing the flush valve or overfilling past the float. From there it's a new fill valve, a new flush valve diaphragm or a full valve replacement, set to the correct water line so the toilet flushes properly and stops cleanly.
Kingston upon Thames's hard water scales up valve seals quickly, especially in rental properties where the toilet gets heavy use. Where a cistern has repeatedly failed we fit better-quality valves rather than the cheapest like-for-like, so you're not calling us back next year.
When your boiler dies on a Sunday morning or a pipe bursts under the kitchen sink, the last thing you want is a national callout line dispatching whoever's "nearest" — sometimes an hour away. Maxfix Plumbing and Heating is based in Kingston upon Thames.
Areas of Kingston upon Thames we cover: Kingston town centre, Norbiton, Coombe, Canbury, Kingston Hill.

Frequently asked
Your questions, answered
How much water does a running toilet waste?
A steady trickle can waste 200–400 litres a day. On a water meter in Kingston upon Thames that adds up quickly, so the repair usually pays for itself within months.
Why does my toilet refill on its own now and then?
That's a slowly leaking flush valve seal letting the cistern drain into the pan until the fill valve kicks in. Replacing the seal or valve fixes it.
Can you repair concealed and back-to-wall cisterns?
Yes — we work on concealed frames and back-to-wall units regularly, accessing through the flush plate where the design allows.
Do you carry parts for older cisterns?
We carry universal fill and flush valves that suit most older Kingston upon Thames cisterns, so the majority of jobs are completed on the first visit.
