How to Fix Loud or Broken Fill Valve
Noisy toilet? There is nothing more embarrassing than flushing your toilet to hear a squeal or loud noise from your fill valve. If you can hear your noisy toilet flushing from any other room than the bathroom, it's time to upgrade to a quiet fill valve.
- First, we have to determine if the water level inside the toilet tank is rising above and spilling into the top of the flush valve overflow tube. If the water level rises above the top of the flush valve overflow tube, the fill valve may not be set to the correct height.
- Confirm that the corner of the fill valve cover lines up with the top of the overflow tube (where the fill valve cover and the black box meet). If the valve is set too high, turn off the water supply and flush the toilet.
- Adjust the height of the valve by twisting the top half of the valve counterclockwise and push down on the valve until the corner of the fill valve cover lines up with the top of the flush valve.
- Turn the top of the valve clockwise to lock it in place. If the fill valve is still hissing and the water level is still rising and spilling into the overflow tube the fill valve may need to be serviced. Check out our service video here.
