How to Remove a Bathroom Sink Faucet Cartridge

Replacing a bathroom sink faucet cartridge is a relatively simple and inexpensive repair that can save you the cost of calling a plumber. The cartridge is a small, replaceable part that controls the flow of water through the faucet. It can become worn or damaged over time, causing leaks or other problems.

There are a few different types of faucet cartridges, so it's important to identify the type you have before you begin. The most common type of cartridge is a compression cartridge, which is held in place by a compression nut. Other types of cartridges include disc cartridges and ball cartridges. Once you have identified the type of cartridge you have, you can follow the steps below to remove it.

Tools and Materials

* Adjustable wrench * Phillips screwdriver * Flashlight

Steps

Turn off the water supply

The first step is to turn off the water supply to the faucet. There will be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise to shut off the water.

Remove the faucet handle

Once the water supply is turned off, you can remove the faucet handle. There will be a small screw on the top of the handle that you need to remove with a Phillips screwdriver. Once the screw is removed, you can pull the handle straight up to detach it from the faucet.

Remove the cartridge retaining nut

With the handle removed, you will see the cartridge retaining nut. This nut is usually made of plastic and is located at the base of the faucet. Use an adjustable wrench to loosen the nut by turning it counterclockwise. Once the nut is loose, you can remove it by hand.

Remove the cartridge

Once the retaining nut is removed, you can remove the cartridge. The cartridge will be held in place by a small spring. Use a flashlight to look inside the faucet and locate the spring. Use a pair of needle-nose pliers to carefully remove the spring.

Install the new cartridge

With the old cartridge removed, you can now install the new cartridge. Insert the new cartridge into the faucet and push it down until it is seated. Replace the spring and the cartridge retaining nut. Tighten the nut by turning it clockwise with an adjustable wrench.

Reattach the faucet handle

Once the new cartridge is installed, you can reattach the faucet handle. Align the handle with the stem and push it down until it snaps into place. Replace the screw on the top of the handle to secure it.

Turn on the water supply

Once the faucet is reassembled, you can turn on the water supply. Check for leaks around the base of the faucet. If there are no leaks, the repair is complete.

Conclusion

Replacing a bathroom sink faucet cartridge is a relatively simple and inexpensive repair that can save you the cost of calling a plumber. By following the steps outlined in this guide, you can quickly and easily replace the cartridge and get your faucet working properly again.
