How to Remove Cartridge from American Standard Bathroom Faucet

A leaking or malfunctioning cartridge in an American Standard bathroom faucet can be a frustrating issue. Replacing the cartridge is a relatively simple task that can be completed in a few minutes with the right tools and a bit of guidance. Here's a comprehensive guide to help you remove the cartridge from your American Standard bathroom faucet:

Step 1: Gather Your Tools

Before you begin, you will need to gather the following tools:

Adjustable wrench or cartridge puller
Flathead screwdriver or Allen wrench (depending on the faucet model)
Clean cloths or rags
Replacement cartridge (if available)

Step 2: Turn Off the Water Supply

Locate the water supply valves under the sink and turn them off to prevent water from flowing while you work on the faucet.

Step 3: Remove the Handle

Using a flathead screwdriver or Allen wrench, remove the screw that secures the handle to the faucet. Then, gently pull the handle straight up to remove it.

Step 4: Remove the Escutcheon Plate

The escutcheon plate is the decorative cover that surrounds the base of the handle. Grip it firmly and pull it straight up to remove it.

Step 5: Access the Cartridge

Once the escutcheon plate is removed, you will see the cartridge assembly. It is typically held in place by a retainer nut.

Step 6: Remove the Retainer Nut

Using the adjustable wrench or cartridge puller, carefully loosen the retainer nut. Turn the nut counterclockwise until it is completely removed.

Step 7: Remove the Cartridge

Once the retainer nut is removed, you can pull the cartridge straight out of the faucet. Be careful not to damage the O-rings or seals on the cartridge.

Step 8: Inspect the Cartridge

Inspect the removed cartridge for any visible damage or corrosion. If the cartridge is damaged or worn, it will need to be replaced.

Step 9: Install the New Cartridge (if available)

If you have a new cartridge, insert it into the faucet body. Align the notches on the cartridge with the corresponding slots in the faucet. Push the cartridge firmly into place.

Step 10: Reassemble the Faucet

Reassemble the faucet in reverse order of disassembly. Tighten the retainer nut securely, replace the escutcheon plate, and insert the handle.

Step 11: Turn On the Water Supply

Turn on the water supply valves and check for leaks. If there are no leaks, your faucet repair is complete.

Tips:

If you have difficulty removing the retainer nut, apply a penetrating oil to the threads and let it sit for a few minutes.
Use a flashlight to help you see inside the faucet while working.
If you are not comfortable replacing the cartridge yourself, contact a qualified plumber for assistance.
