Full Toilet Cistern Overhaul in Allesley, Coventry: Stopping a Constantly Running Toilet

A constantly running toilet is one of those problems that's easy to ignore, until you realise just how much water (and money) it quietly wastes every single day. We were recently called out to a home in Allesley, Coventry to deal with exactly that: a cistern that wouldn't stop running. Here's how our team at First Call Home Services Coventry put it right.

The Problem

The customer's toilet had been running non-stop, with water trickling away around the clock. When we opened up the cistern to investigate, the cause was clear. The fill and flush valve, the part that controls how the toilet refills and flushes, was covered in years of heavy limescale and corrosion. Coventry's hard water is tough on toilet internals over time, and in this case the build-up had worn the mechanism to the point where it could no longer seal properly. The result was a steady, wasteful flow of water that simply never stopped.

The Work We Did

Rather than patch a single failing part, we carried out a full cistern overhaul to make sure the whole system would work reliably for years to come. We stripped out the old, corroded internals, removed the limescale-clogged components, and fitted a fresh, properly functioning fill and flush valve along with new working parts.

The heavy limescale and corrosion made the job more stubborn than a standard valve swap. Seized and crusted components always take extra care and patience to remove without damaging the cistern itself. But taking the time to do it properly meant we could leave the customer with a clean, fully working unit rather than a quick fix that would fail again down the line.

The Result

With the overhaul complete, the constant running stopped immediately. No more wasted water, no more trickling overnight, and a toilet that flushes and refills exactly as it should. The difference between the before and after photos says it all, from a grimy, limescaled valve to a clean, properly working mechanism. The customer was left with a quieter, more efficient toilet and lower water waste going forward.
