Rebuilding your American Standard toilet can save you hundreds of dollars.
After repairing your American Standard toilet several times without success, it's time to rebuild. Replacing all the internal parts in your toilet is the only way to be certain you will not have any problems. Rebuilding you're American Standard toilet is not as hard as you might think. The whole job should only take an hour or two.
Instructions
1. Close the toilet's water supply valve under the left side of the tank. Rotate the valve's handle clockwise until it stops. Remove the tank lid and set it aside on a soft surface.
2. Flush the toilet and continue to hold the handle down to remove as much water as possible. Soak up the rest of the water in the toilet tank with a hand towel.
3. Disconnect the water supply line from the water fill valve with a pair of pliers. Place the hand towel under the supply line to catch what water is left in the supply line and fill valve.
4. Unscrew the fill valve's lock nut under the tank and lift the fill valve out of the tank. Disconnect the small refill tube from the top of the flush valve as you remove the fill valve.
5. Unscrew the tank-to-bowl bolt locknuts from under the toilet tank with a small adjustable wrench. You may need to hold the top of the bolts with a flat tip screwdriver from inside the tank.
6. Lay the American Standard toilet tank down on top of the toilet seat. You might want to place an old bath towel down on top of the toilet seat first; this will help keep the seat clean and prevent damage.
7. Peel off the black foam rubber tank-to-bowl gasket from the flush valve on the bottom of the tank. The old black rubber material will get everywhere, wear gloves and have a trash bag handy to deposit the gasket.
8. Unscrew the fill valve's large lock-nut from the bottom of the toilet tank. Turn the nut counterclockwise to remove. You will need a large pipe pair of Channel lock pliers or a large pipe wrench. Hold the flush valve with one hand from inside the tank to prevent it from turning.
9. Clean the inside of the toilet tank around the fill valve and flush valve openings with an old rag.
10. Install a flush valve and fill valve according to the manufacturer's instructions. Reinstall the tank with new tank-to-bowl bolts and new tank-to-bowl gasket. Connect the water supply line and turn the water back on. Set the water level in the tank a half inch below the top of the new flush valve refill tube. Flush the toilet and adjust the water fill valve if necessary.
Tips Warnings
If you cannot get the nuts off the tank bolts, you may need to use a hacksaw blade and just cut them in between the tank and the bowl.
You can break the toilet easily, so use caution when moving parts.
