Shut Off the Water Supply
Before you do anything, you'll need to shut off the water supply to your American Standard kitchen faucet. Locate the shut-off valves beneath the sink and turn them clockwise to close them.
Remove the American Standard Faucet Handle
Once the water is shut off, you can remove the handle of your American Standard kitchen faucet. Use an Allen wrench to remove the set screw that holds the handle in place. Once the set screw is removed, you should be able to pull the handle off. Lift the handle up straight to remove it from the faucet stem.

Remove the Bonnet or Hex Nut
With the handle of your American Standard faucet removed, you should be able to see a bonnet or hex nut. Use an adjustable wrench to remove this piece. If the bonnet is stuck, you may need to use a pair of pliers to get it started.
Remove the Collar of American Standard Faucet
Under the bonnet, you will find a collar. This piece is threaded and can be removed by hand. Put on a rubber glove to increase traction, grip the collar on the top of the American Standard faucet body and turn it counterclockwise. You may need to channel lock pliers to keep things moving.
Remove the Stem of American Standard Faucet
Once the collar is removed, you should be able to pull the stem out of the American Standard faucet. If it is stuck, you may need to use a pair of pliers. Remove the stem by pulling it straight up and out of its housing. Use pliers, if necessary, gripping the spindle at the top of the stem.
Remove the Ball, Gaskets, and Springs
The next step is to remove the ball, gaskets, and springs. The ball is located under the stem of your American Standard kitchen faucet and is held in place by a screw-on cap. Unscrew the cap with a Phillips head screwdriver and pull out the ball. Remove the gaskets and springs from around the ball. Inspect all of these parts for any damage and replace them if necessary.
Remove Mineral Deposits
Mineral deposits can accumulate on the ball, seat washer, and in the American Standard faucet body over time. Use a brush and white vinegar to remove any mineral deposits that may have built up. Removing mineral deposits is one of the incredible uses for white vinegar as it helps to soak the deposits. If the ball is cracked or chipped, replace it with a new one.
Install a New Seat and Spring
Once the ball, seat washer, and faucet body are clean and free of mineral deposits, you can install a new seat and spring. Start by inserting the seat into the American Standard faucet body. Make sure it is seated correctly, and then screw on the retaining nut. Tighten the nut with a wrench until it is snug.
Reinstall the Stem of American Standard Faucet
Apply a small amount of plumber's grease to the o ring at the base of the valve stem. If possible, you can also replace the o ring, which is sometimes included in the American Standard repair kit, or the entire stem. Fit the stem into its housing, aligning the tabs on the stem with the slots in the housing.
Push the stem all the way down until it stops. Reinstall the bonnet nut and tighten it carefully with pliers or an adjustable wrench. It should be snug but don't over-tighten, or you may damage the American Standard faucet.

Check the Leaking and Reinstall the Handle
Turn on the water at the shut-off valves and check for leaks around the base of the American Standard faucet. If necessary, use a wrench to tighten the packing nut slightly until the leak stops.
Replace the handle, making sure that it is in the correct position according to American Standard's instructions. Some handles have an indicator line or arrow that must be aligned with the stem. Others are keyed so that they can only be installed in one position.
Turn on the water and check for leaks again. If necessary, repeat the previous steps until the leak stops.
Test Your Newly Installed American Standard Faucet
Run your newly installed American Standard faucet for a few minutes to make sure that it is working properly. Check for any leaks and make sure that the water pressure is adequate. If everything seems to be working properly, you have successfully installed your new American Standard kitchen faucet. Note that American Standard is one of the best kitchen faucets with sprayers, so it will be able to serve you for a long time without a fix.
