Turn the handles of the faucet to the open position to release any remaining water in the lines.Next, remove the faucet handle.

Inspect the old cartridge for any damage or wear, and take it with you to the hardware store to ensure you purchase the correct replacement.With the old cartridge removed, it’s time to install the new one. Simply reverse the removal process: insert the new cartridge into the faucet body, reattach the retaining nut, and tighten it securely but be careful not to overtighten as this can damage the faucet.Reattach the handle by sliding it back on and securing it with the set screw. Turn the water supply back on and check for any leaks.
