To remove and replace a kitchen faucet cartridge for better performance, first, turn off the water supply. Remove the faucet handle by unscrewing the set screw. Then, take off the escutcheon or cover to access the cartridge. Pull out the old cartridge and insert a new one, ensuring it’s properly aligned. Reassemble the faucet and turn the water back on to test for leaks and smooth operation.

Replacing the cartridge can improve the faucet’s performance, addressing issues like leaks or uneven water flow. A new cartridge ensures efficient water distribution and extends the faucet’s lifespan. Proper installation is key to achieving optimal performance.
