Whether you're dealing with a leaky faucet or simply upgrading your fixtures, knowing how to remove the cartridge is essential. In this guide, we'll walk you through the entire process step-by-step, ensuring you have all the information you need to succeed. First, gather your tools: you'll need an adjustable wrench, a flathead screwdriver, and possibly a Phillips screwdriver, depending on your faucet model. Before you start, make sure to turn off the water supply to your faucet. This is usually located under the sink. Once the water is off, open the faucet to relieve any remaining pressure. Next, remove the faucet handle. This typically involves loosening a screw that is either located on the back or under the handle. If your faucet has decorative caps, you may need to pry these off to access the screws. After removing the handle, you should see the retaining nut that holds the cartridge in place. Use your adjustable wrench to loosen and remove this nut carefully. Be cautious not to apply too much pressure, as you don’t want to damage the surrounding plumbing or hardware. With the retaining nut removed, you can now pull the cartridge out of the faucet body. If it’s stuck, you may need to wiggle it gently or use your flathead screwdriver to pry it out. Once the cartridge is removed, inspect it for any signs of wear or damage. If you’re replacing it, take the old cartridge to the hardware store to ensure you get an exact match. Installing the new cartridge is simply the reverse of the removal process. Insert the new cartridge into the faucet body, reattach the retaining nut, and then replace the handle. Finally, turn the water supply back on and check for any leaks. If everything is tight and secure, you’ve successfully removed and replaced your bathroom faucet cartridge!Tips 1:Remember to keep a towel handy to catch any drips while you work.
