How To Adjust The Fill Valve In A Toilet

Adjusting the fill valve in a toilet is an important part of maintaining the toilet and ensuring it functions properly. If your toilet is running constantly, it is likely that the fill valve needs to be adjusted. Here is how you can adjust the fill valve in a toilet:

  • Shut off the water supply. Find the shut off valve located near the base of the toilet, usually underneath the tank. Turn the valve in a clockwise direction to turn it off.
  • Remove the tank cover. Place a towel underneath the tank cover to absorb any water that spills out. Unscrew the tank cover and set it aside.
  • Adjust the fill valve. Use a screwdriver to turn the adjustment screw on the side of the fill valve. Turning the screw clockwise will reduce the water level in the tank, while turning it counterclockwise will increase the water level. Adjust the water level to be about 1 inch below the top of the overflow tube.
  • Replace the tank cover. Place the tank cover back on the tank and screw it in place. Make sure the gasket is properly aligned and the tank is secure.
  • Turn the water back on. Turn the shut off valve in a counterclockwise direction until the water is fully turned on.

Once the fill valve is adjusted, the water level in the tank should remain the same. If the water level is still too low or too high, the fill valve may need to be replaced. If the toilet is still running after adjusting the fill valve, the flush valve may need to be adjusted or replaced.

Adjusting the fill valve in a toilet is an important task for toilet maintenance and keeping it running smoothly. With the right tools and a bit of knowledge, it is a relatively simple job.
