How to Repair an American Standard Faucet
- 1). Turn off the water supply where the American Standard faucet is installed. In a bathroom or kitchen sink, for example, look underneath the sink to find the water supply shut-off valves. The valves will be two rounded knobs that have pipes or hoses leading to the sink above. Rotate these valves clockwise to turn off the water supply. Open the faucet to allow any water inside to run out.
- 2). Pry the faucet handle screw cover off with the edge of a flat-head screwdriver. The screw is usually disguised with the "Hot" or "Cold" label on the top. Pop the cap off, and set aside. Remove the faucet handle screw with a Phillips screwdriver. Pull the handle straight off.
- 3). Remove the packing nut with a pair of channel lock pliers or an adjustable wrench by turning counterclockwise. This part is the first hexagonal nut at the top of the stem. Lift it off the faucet handle stem. Remove the faucet stem itself by turning the second hexagonal nut counterclockwise. Pull it out of the faucet socket.
- 4). Examine the faucet stem. If it is corroded or cracked, repair it by replacing it with a new one. Clean off any lime buildup with a stiff wire brush.
- 5). Turn the faucet stem over. Examine the rubber washer on the bottom. If it is torn or otherwise damaged, replace it. In this case, unscrew the retaining screw at the bottom of the stem. Pull out the washer with your fingers or a pair of needle-nose pliers. Slip a new washer onto the end of the faucet, and secure with the screw. Apply a few drops of silicone grease to the outside of the washer.
- 6). Wrap the threads on the valve stem with plumber's tape. Wrap the tape two turns around the stem. Trim off any excess with scissors. Insert the stem into the valve socket. Tighten with the wrench.
- 7). Squeeze a few drops of silicone grease onto the inside of the packing nut. Slip the nut back over the stem. Tighten with the wrench.
- 8). Slip the faucet handle back over the stem. Insert the faucet handle screw and tighten. Replace the faucet handle screw cap.
- 9). Restore the water supply.
