Fill Valve Replacement in Salisbury

Local Toilet Repairs by Just Toilets

What Is a Fill Valve?

A fill valve is the part inside your toilet cistern that controls how the cistern refills with water after you flush.
Once the flush valve has emptied the cistern, the fill valve opens to let fresh water in and then shuts off automatically when the correct water level is reached.

Modern toilets usually use a compact plastic fill valve, designed to be quieter and more water-efficient than older ball-cock systems.

Why Do Fill Valves Need Replacing?

Fill valves wear out over time and are one of the most common causes of toilet problems. Typical reasons include:

  • Rubber seals and diaphragms are degrading
  • Limescale buildup (very common in Salisbury’s hard-water areas)
  • Valves sticking open or failing to shut off
  • Internal components are wearing or snapping
  • Older fill valves are becoming unreliable or obsolete
  • In many cases, replacing the fill valve is more reliable and cost-effective than attempting a repair.

Signs Your Fill Valve Has Failed

  • If you notice any of the following, the fill valve is often the cause:
  • Toilet keeps refilling after flushing
  • Cistern takes a very long time to fill
  • Hissing or constant water noise from the cistern
  • Toilet refills by itself without being flushed
  • Higher water bills with no visible leak
  • Water level too high or too low in the cistern
