Instructions for Replacing a Cartridge in a Faucet
Now that you have the right materials and tools and have taken the necessary safety precautions, follow these step-by-step instructions to replace the cartridge in your faucet:
Step 1: Remove the Handle
Use a screwdriver or an Allen wrench to remove the screw or set the screw that holds the handle in place. Depending on your faucet model, the screw may be located under a cap or a button. Once you remove the screw, pull the handle off the faucet. If the handle is stuck, use pliers to twist it gently back and forth until it loosens.
Step 2: Remove the Cartridge
Use an adjustable wrench to loosen the nut that secures the cartridge to the faucet body. Turn the wrench counterclockwise and remove the nut. If the nut is stuck or corroded, use pliers to grip it firmly and twist it gently. Once you remove the nut, pull the cartridge out of the faucet body. If the cartridge is stuck, use pliers to wiggle it back and forth until it comes loose.
Step 3: Clean and Inspect the Faucet
Use white vinegar or lime remover and a clean rag to clean the inside of the faucet body and remove any mineral buildup. Inspect the O-rings, the springs, and the valve seat for damage
Step 4: Install the new cartridge
Now that the old cartridge has been removed, it’s time to install the new cartridge. Carefully place the new cartridge into the faucet and make sure it is oriented in the correct direction. You should be able to feel the cartridge click into place.
Step 5: Tighten the cartridge
Using the basin wrench, carefully tighten the cartridge in place. Be sure not to over-tighten, as this can damage the cartridge and cause leaks.
Step 6: Re-install the handle
Once the cartridge is securely in place, reattach the handle to the faucet. Use the adjustable wrench to tighten the handle in place. Again, be careful not to over-tighten the handle.
Step 7: Test the faucet:
Before turning the water supply back on, test the faucet to make sure it is functioning properly. Turn the handle on and off a few times and check for any leaks. If everything looks good, turn the water supply back on and test the faucet again.
If you encounter any problems while replacing the cartridge, there are a few things you can do to troubleshoot the issue:
- Make sure the O-rings are properly installed: O-rings are used to make a tight seal between the faucet and the cartridge. If the O-rings are not installed properly, they can cause leaks. Check to make sure the O-rings are in the right place before tightening the faucet.
- Make sure you’re using the right size wrench: Using the wrong size adjustable wrench can cause you to strip the nuts or bolts, making it difficult to remove or tighten them. Make sure you’re using the correct size wrench for your faucet.
- Check all connections: If you’re experiencing leaks, check all connections to make sure they’re tightly secured. Leaks are a common problem when replacing a cartridge, so make sure everything is tightly in place.
- Clean the O-rings: If you notice any dirt or debris on the O-rings, clean them before re-installing. This will ensure a tight seal and prevent leaks.

Removing a stuck faucet cartridge can be a difficult task but there are some things you can do to fix this problem.
