Delta Sink Faucet Cartridge Replacement

Replacing a cartridge in a Delta sink faucet is a relatively simple plumbing repair that can be completed in under an hour. The cartridge is a small, cylindrical device that controls the flow of water in the faucet. Over time, cartridges can become worn or clogged, leading to leaks or changes in water pressure. By following these step-by-step instructions, you can easily replace the cartridge in your Delta sink faucet and restore it to proper working order.

Tools and Materials Needed:

New Delta sink faucet cartridge
Adjustable wrench
Phillips screwdriver
Hex key (optional)
Paper towels or cloth
Bucket or bowl

Step-by-Step Instructions:

1. Turn off the water supply: Before you begin working on the faucet, shut off the water supply to the sink. There should be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to close them.

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

3. Remove the aerator: The aerator is the small, mesh screen located at the tip of the faucet spout. Use a pair of pliers to unscrew the aerator and remove it from the faucet.

4. Remove the retainer clip: Once the aerator is removed, you will see a small retainer clip holding the cartridge in place. Use a hex key or a small flathead screwdriver to pry the retainer clip up and remove it.

5. Remove the cartridge: Grip the cartridge with a cloth or paper towels and pull it straight up out of the faucet body. The cartridge may be slightly stuck, so you may need to wiggle it back and forth to loosen it.

6. Insert the new cartridge: Take the new cartridge and insert it into the faucet body. Align the notches on the cartridge with the slots in the faucet body and push the cartridge down until it is fully seated.

7. Reinstall the retainer clip: Place the retainer clip over the cartridge and press it down to secure the cartridge in place.

8. Reinstall the aerator: Screw the aerator back onto the faucet spout.

9. Reinstall the handle: Align the handle with the faucet and slide it down onto the cartridge stem. Tighten the screw to secure the handle.

10. Turn on the water supply: Open the shut-off valves under the sink to restore the water supply to the faucet. Check for any leaks around the faucet and make sure the water is flowing smoothly.

Congratulations! You have successfully replaced the cartridge in your Delta sink faucet. If you encounter any difficulties during the repair process, consult the faucet manufacturer's instructions or contact a qualified plumber for assistance.
