How to Repair a Leaking American Standard Bath Tub Faucet
- 1). Turn the main water valve off, located on the exterior of the home, near the water meter. For apartment or condo dwellers, look for a hidden access panel built into a wall near the bathtub in the bathroom. This access panel may be in the utility room if the room shares a wall with the bathroom. If you cannot locate the bathtub shut-off valve, contact the building supervisor and have them show you where it is located before you begin.
- 2). Allow the remaining water in the bathtub faucet lines to run out by turning the faucet handle in the open, or on, position.
- 3). Close the bathtub drain to prevent any parts from being lost.
- 4). Insert a small flat-head screwdriver into the faucet handle cap, which covers the handle screw. Unscrew the handle screw with a screwdriver. If your American Standard bathtub faucet does not have a handle cap, insert an Allen wrench into the side slot and remove the handle. Set the handle screw and cap to the side for re-installation. For two-handled faucets, repeat this process for the other side.
- 5). Wiggle and pull on the American Standard bathtub faucet handle until it comes off. Use a handle puller for older, stuck faucet handles. Remove the escutcheon cover plate by unscrewing with a screwdriver, or grasping it with your fingers and sliding it off the handlebar.
- 6). Remove the American Standard faucet stem assembly with a bath socket. Place the bath socket over the stem bonnet and turn counterclockwise. Unscrew the stem assembly with the bath socket, and remove.
- 7). Unscrew the tiny screw attaching the washer to the stem assembly with a small screwdriver, and remove the washer. Set all parts you are removing aside in a safe location.
- 8). Take the washer and tiny screw to a local hardware store and have an associate match them to new replacement pieces. Purchase two for two-handle American Standard faucets, or one for one-handle American Standard faucets.
- 9). Grease the washer and screw with plumber's lubricant, and replace them back onto the end of the stem assembly. Smear a small amount of plumber's lubricant onto the stem assembly threads, and reassemble the stem into the faucet body with the bath socket.
Replace the escutcheon cover plate and handle in the reverse order for re-installation.
Turn the water back on from the main water valve.
