- Turn off the water supply to the toilet.
- Remove the float valve cap assembly by rotating it 1/4 run counterclockwise. Lift the float arm as you rotate. The arm should be used as leverage. NOTE: the cap may be a different color that the one pictured (Fig. 1).
- Remove the rubber seal (diaphragm) from the cap and rinse it under running water to clear debris that may have collected.
- Inspect the rubber seal for damage (tears, holes, etc.) that may keep diaphragm seal from properly sealing (Fig. 2).
- Turn the water supply on so that the water slowly comes out of fill valve. Keep water on for approximately 20-30 seconds to wash out any debris from inside the fill valve. TIP: Hold a disposable cup over the uncapped fill valve to avoid splash from the fill valve if the water is turned on too high (Fig. 3).
- Turn off the water supply.
- Reinstall the rubber seal inside the fill valve assembly cap.
- Reattach the cap assembly by rotating 1/4 turn clockwise. Give the cap a slight tug up to be sure the cap is secure ( Fig. 4).
- Turn on the water supply to the toilet.
NOTE: If the attempt to control the tank water level is unsuccessful, and the float valve continues to fill the tank, replace the float valve seal to restore the ability of the float valve to shut off the water supply.
