Identifying any faucet is the first step in determining which parts you'll need to repair the appliance. If you are wondering what type of shower faucet you have, and think it may be an American Standard model, the identification process is fairly straight-forward. It involves visual inspection of the faucet and the parts and simple matching of images. If you have some plumbing or home repair experience this project will only take about 10 minutes.
Step 1
Turn off the faucet water supply if the faucet is installed. Access the shower water pipe valves behind the shower wall, or turn off the home's main water supply.

Step 2
Look on the base of the shower faucet spout on the front. American Standard shower faucets have the words "American Standard" printed on them. If your faucet is corroded or has lime scale, spray with a cleaning agent and wipe it with a towel to make the letters legible. Or, locate American Standard on the trim piece surrounding the shower faucet handle.
Step 3
Match the faucet visually using pictures from the company's website or from a repair part book (your hardware store or plumbing outlet will have one handy). Start by selecting the type of faucet it is (in this case a shower faucet) and search using this criteria. Visit the main website of American Standard Faucet and also select the type of faucet to begin. A list of repair parts will populate with your faucet.
Step 4
Match the handle, spout and inner parts to the images you find to determine the exact make and model.
Step 5
Remove the set screw in the handle with an Allen wrench and take off the handle. Remove the three set screws in the cartridge with a Phillips screwdriver and pull the cartridge out. View and match the cartridge to the parts you find on the website or in the plumbing parts book.
Tip
If your faucet does not have three screws in the cartridge under the handle, it is not an American Standard faucet.
