If water is dripping or running constantly from an overflow pipe on your property, you’re probably dealing with a faulty valve, a worn washer, or a blocked warning pipe — and it won’t fix itself. Our Crawley plumbing team repairs overflow pipes on toilets, tanks, cisterns and bathtubs every week, and most jobs are sorted in a single visit.
We cover Crawley and the surrounding areas, including Horley, Three Bridges, Ifield, and Pound Hill, with same-day appointments available for urgent overflow problems.
An overflow pipe is designed to only run when something upstream has gone wrong. If you’re noticing any of the following, it’s worth getting it looked at before it wastes water or causes damage:
A constantly running overflow usually means the float valve (ballcock) isn’t shutting off the water supply properly, or the washer inside has worn out. Left unfixed, this can waste hundreds of litres of water and, in some cases, lead to water damage.
Faulty float valves and worn washers are the most common cause of a toilet cistern that won’t stop filling or overflows into the pan. We replace or adjust the ballcock, float, and inlet valve to stop the leak at the source.
Loft-based cold water tanks can overflow due to a stuck or failed float valve. We check the tank, valve, and warning pipe, and repair or replace parts as needed — including insulation checks to prevent future issues.
Whether it’s a low-level or high-level cistern, a slow drip from the overflow pipe almost always points to a worn valve seal. We diagnose and fix this quickly, usually without needing to replace the whole cistern.
If your bath overflow drain isn’t clearing water fast enough, or is leaking behind the bath panel, we inspect the overflow assembly and pipework to resolve blockages or leaks.
Where a warning pipe is cracked, incorrectly positioned, or beyond repair, we replace it to current standards so it drains safely to the outside of the property.
