- Turn off the water supply to the toilet.
- Rotate the large white cap 1/8 turn counterclockwise (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 cap. The nipple on the seal should go in towards the white cap (Fig. 4).
- Reinstall the cap by pushing it onto the fill valve and turning 1/8 turn clockwise until you hear a "click" (Fig. 4).
- Turn on the water supply to the toilet.
