Materials You’ll Need:

Steps for Replacing the Flush Valve Seal:
#1. Turn Off the Water Supply
Locate the water supply valve behind the toilet and turn it clockwise to shut off the water flow. Flush the toilet to drain any remaining water in the tank.
#2. Remove the Toilet Tank Lid
Lift the toilet tank lid off and set it aside.
#3. Disconnect the Supply Line
Use an adjustable wrench to loosen the nut connecting the supply line to the fill valve at the bottom of the tank. Disconnect the line by hand.
#4. Remove the Flush Valve
Unscrew the large nut at the base of the flush valve using an adjustable wrench. Carefully lift the flush valve straight up and out of the tank.
#5. Remove the Old Seal
Use a flathead screwdriver to pry the old flush valve seal out of its groove. Discard the old seal.
#6. Apply Plumber’s Putty
Roll a small piece of plumber’s putty into a rope and apply it around the rim of the new flush valve seal. This will help create a tight seal.
#7. Lubricate the Seal (Optional)
Apply a small amount of lubricant to the new seal’s surface to make it easier to install.
#8. Install the New Seal
Place the new flush valve seal into the groove on the bottom of the flush valve. Press down firmly to ensure it is seated properly.
#9. Reinstall the Flush Valve
Align the flush valve with the hole in the bottom of the tank and carefully insert it. Tighten the nut at the base of the flush valve with an adjustable wrench.
#10. Reconnect the Supply Line
Hand-tighten the nut connecting the supply line to the fill valve. Use an adjustable wrench to fully tighten the nut.
#11. Turn On the Water Supply
Slowly turn the water supply valve back on. Check for leaks around the base of the flush valve.
#12. Adjust the Water Level
If necessary, adjust the water level in the tank by bending the fill valve arm. The water level should be about an inch below the top of the overflow tube.
#13. Test the Flush Valve
Flush the toilet to test the new flush valve seal. Ensure there are no leaks and that the toilet flushes properly.
Troubleshooting:
- Toilet is still leaking: Check the flush valve seal to ensure it is properly installed and seated. If necessary, replace the seal.
- Toilet won’t flush: The flush valve may be blocked. Remove the flush valve and clean it with a wire brush or vinegar.
- Weak flush: The water level in the tank may be too low. Adjust the fill valve arm to raise the water level.
Conclusion:
Replacing the flush valve seal on an American Standard toilet is a relatively simple repair that can save you time and money. By following these steps, you can restore your toilet to optimal performance and prevent future leaks.
