If water is uncontrolled or approaching electrical equipment, prioritise safety and call a plumber. The guidance below is general and does not replace an inspection.

Understanding the issue

Continuous water into the bowl may come from the flush valve, fill valve or an overflow arrangement. The sound of filling alone does not identify the fault. Persistent running can waste water even without a floor leak.

Before arranging the visit

Describe whether the cistern stops filling and whether water is visible in the bowl.

Choosing the appropriate plumbing visit

We check the visible fault, isolation, pipe condition and access before agreeing the repair scope. Our toilets & cisterns page explains the related work and how an assessment is arranged.

Where the findings point to running toilet repair, read the running toilet repair service details before discussing the repair scope. The actual fitting and access determine the work needed.

Information worth keeping

Record when the issue occurs, the affected room and any previous repair. For a property in our home area, plumbing in West Bridgford explains the local enquiry route; check the coverage directory for another postcode.
