How to Replace a Delta Bathroom Sink Cartridge

Replacing a Delta bathroom sink cartridge is a relatively simple task that can be completed in about 30 minutes with the right tools. A cartridge is a small, cylindrical device that controls the flow of water in a faucet. Over time, cartridges can become worn or damaged, leading to leaks, drips, or other problems.

Step 1: Gather Your Tools

Before you begin, gather the following tools and materials:

Phillips head screwdriver
Flat head screwdriver
Adjustable wrench
New Delta bathroom sink cartridge
Paper towels
Bucket

Step 2: Turn Off the Water Supply

Locate the water supply valves under the sink and turn them off completely. This will prevent water from flowing out while you are working on the faucet.

Step 3: Remove the Handle

Use a Phillips head screwdriver to remove the screws that hold the handle in place. Once the screws are removed, pull the handle straight up to detach it from the faucet.

Step 4: Remove the Escutcheon Plate

The escutcheon plate is the decorative cover that surrounds the base of the faucet. Use a flat head screwdriver to pry the escutcheon plate loose and remove it from the faucet.

Step 5: Remove the Cartridge

Use an adjustable wrench to loosen the packing nut that holds the cartridge in place. Once the packing nut is loose, pull the cartridge straight out of the faucet body.

Step 6: Install the New Cartridge

Insert the new cartridge into the faucet body. Make sure that the cartridge is oriented correctly, with the splines on the cartridge aligned with the splines in the faucet body.
