Step-by-Step Guide to Replacing the Delta Faucet Cartridge

1. Turn Off the Water Supply:

Locate the water supply valves under the sink. Turn both the hot and cold water valves clockwise to shut off the water supply to the faucet.

2. Remove the Handle:

Using the appropriate screwdriver, remove the screw that secures the faucet handle in place. Grip the handle firmly and pull it straight off the faucet.

3. Remove the Aerator:

The aerator is usually located at the tip of the faucet. Use a wrench to loosen the aerator and remove it carefully.

4. Loosen the Bonnet Nut:

Underneath the aerator, you'll find a bonnet nut. Use the adjustable wrench to loosen the bonnet nut counterclockwise.

5. Remove the Cartridge:

Once the bonnet nut is loose, you should be able to pull the cartridge straight out of the faucet body. Be careful not to drop any parts into the drain.

6. Inspect the Cartridge:

Inspect the old cartridge for signs of damage or wear. If the O-rings are worn out or if there are mineral deposits built up, it's time to replace it.

7. Install the New Cartridge:

Take the new cartridge and insert it into the faucet body. Push it in until it's seated properly.

8. Replace the Bonnet Nut:

Screw the bonnet nut back in place and tighten it using the adjustable wrench.

9. Reinstall the Aerator:

Screw the aerator back onto the faucet.

10. Reinstall the Handle:

Align the handle with the faucet body and insert the screw. Tighten the screw to secure the handle in place.

11. Turn on the Water Supply:

Turn the water supply valves counterclockwise to restore water flow to the faucet.

12. Test the Faucet:

Turn on the faucet and check for leaks. If you notice any leaks, tighten the bonnet nut or other fittings until the leak stops.

By following these steps, you should be able to successfully replace the Delta bathroom faucet cartridge and restore your faucet to proper working condition.
