Replace Delta Bathroom Sink Cartridge: A Step-by-Step Guide

A dripping or leaking bathroom faucet can be a major annoyance. Not only is it a waste of water, but it can also be noisy and disruptive. If your Delta bathroom sink faucet is giving you trouble, it's likely that the cartridge needs to be replaced. Replacing a Delta bathroom sink cartridge is a relatively simple task that most homeowners can do themselves. Here's a step-by-step guide to help you get the job done.

Tools and Materials You'll Need

Before you begin, gather the following tools and materials:

Phillips head screwdriver
Adjustable wrench
New Delta bathroom sink cartridge
Paper towels or a rag

Step-by-Step Instructions

1. Turn off the water supply. Under the sink, locate the two water supply lines that connect to the faucet. Use the adjustable wrench to turn off the water supply by turning the nuts clockwise.

2. Remove the handle. Use the Phillips head screwdriver to remove the screw that secures the handle to the faucet. Once the screw is removed, pull the handle straight up to remove it.

3. Remove the cartridge retainer clip. Inside the faucet, you will see a small plastic cartridge retainer clip. Use a flat-head screwdriver to pry the clip loose.

4. Remove the old cartridge. Once the retainer clip is removed, you can pull the old cartridge straight out of the faucet body. Be careful not to lose the small rubber O-rings that are on the cartridge.

5. Install the new cartridge. Insert the new cartridge into the faucet body. Make sure that the O-rings are in place and that the cartridge is fully seated.

6. Replace the cartridge retainer clip. Push the cartridge retainer clip back into place. Make sure that it is fully engaged.

7. Replace the handle. Push the handle back onto the faucet body. Secure it with the Phillips head screw.

8. Turn on the water supply. Open the water supply lines under the sink. Check for any leaks around the faucet.

Tips

If you are replacing the cartridge in a two-handle faucet, you will need to repeat the steps for both handles.
Be careful not to overtighten the cartridge retainer clip. This can damage the clip or the cartridge.
If you are not comfortable replacing the cartridge yourself, you can always call a plumber for help.

Conclusion

Replacing a Delta bathroom sink cartridge is a simple task that most homeowners can do themselves. By following the steps outlined in this guide, you can save yourself the time and expense of calling a plumber.
