The fill valve refills your toilet tank after every flush. When it wears out, you'll hear it. We fix fill valve problems all over Aspen Hill.
Signs of a failing fill valve
- 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
- Hissing or whistling after the tank is full
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.
Aspen Hill homes: what we see
In Aspen Hill's mid-century homes, original supply lines and shutoffs are often due for replacement alongside the fill valve.
Most Aspen Hill homes are on WSSC Water, which licenses plumbers in its service area and runs the cross-connection (backflow) program.
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.

Quick check
Lift the tank lid and watch after a flush. If water keeps flowing into the overflow tube after the tank is full, the fill valve or float is set too high or failing. Turn the shutoff valve off until it's fixed.

Frequently asked questions
Why is my toilet hissing?
Most often a worn fill valve that can't fully shut off.
Should I replace the flapper too?
If it's old, yes. Replacing both together often fixes a running toilet completely.
Can water pressure affect the fill valve?
Yes. Very high pressure can make valves noisy and wear them faster. We can check your pressure.
What's a ballcock?
An older style of fill valve with a float ball on an arm. Modern valves use a float cup.
