Signs of a failing fill valve

  • Hissing or whistling after the tank is full
  • Tank takes a long time to refill
  • Water keeps flowing into the overflow tube
  • Tank doesn't fill to the proper level
  • Toilet won't stop running even with a new flapper
  • Leak at the base of the fill valve under the tank

Why fill valves wear out

Minerals and debris in water wear the seals inside the valve. Over time it can't shut off fully, or it opens slowly. Replacing the entire valve is usually faster and more reliable than rebuilding it.

Brookeville homes: what we see

Many Brookeville homes from the '80s–'90s have fill valves that have been rebuilt more than once. A full replacement is the cleaner fix.

Brookeville has a mix of public water and private wells on larger lots. If you're on a well, let us know — it changes a few things about pressure and water quality we'll check.

Getting the water level right

After install, we set the water level about an inch below the top of the overflow tube (or to the line marked on the tank). Too high and it runs into the overflow; too low and the flush is weak.

Check the supply line too

If the supply line is old or the shutoff valve is stiff, we recommend replacing them at the same time. It's a small cost to prevent a flood from a failed plastic nut.
