Why your toilet keeps running (and why it is worth fixing quickly)
A toilet that keeps refilling after it has already flushed is one of the most common plumbing complaints, and one of the cheapest to fix.
Cause one: the flush valve is not sealing
Over time these wear, warp, or get coated in limescale and stop sealing fully.
Cause two: the fill valve is not shutting off
Water keeps trickling in, usually escaping down the overflow tube.
A quiet cost
One River-village customer only found their toilet had been running for months when a genuinely high water bill arrived. The fix was a £12 part.
When to call rather than DIY
Cisterns vary enough between manufacturers and ages that fitting the wrong part is a common DIY trap.
