The first step is to gather the necessary tools: a wrench, a screwdriver, and replacement cartridges. Make sure to turn off the water supply to your faucet before starting the process. Once the water is off, it’s a good idea to open the faucet to relieve any pressure and drain excess water. Next, you’ll need to remove the handle of the faucet. This is usually done by locating the set screw, which may be hidden under a decorative cap. After removing the screw, gently lift the handle off. With the handle removed, you can now access the cartridge. Use your wrench to loosen and remove the retaining nut that holds the cartridge in place. Once the nut is removed, carefully pull the cartridge out of the faucet body. Take note of how the cartridge is positioned, as you’ll need to insert the new cartridge in the same orientation. Now it’s time to install the new cartridge. Push it into the faucet body, ensuring it fits snugly. Replace the retaining nut and tighten it with your wrench, but be careful not to overtighten. After securing the cartridge, you can reattach the faucet handle by sliding it back into place and tightening the set screw. Finally, turn the water supply back on and test the faucet to ensure it’s working properly. If everything is functioning well, you’ve successfully changed your bathroom faucet cartridge!Tips 1:Always take the old cartridge to the store to find an exact match for your new one.
