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 Clarksburg.
Signs of a failing fill valve
- 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
- Tank takes a long time to refill
- Water keeps flowing into the overflow tube
- Tank doesn't fill to the proper level
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.
Clarksburg homes: what we see
Newer Clarksburg toilets use modern fill valves, but mineral buildup still wears them out after several years.
Most Clarksburg 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.
