Delta Bathroom Sink Faucet Cartridge Replacement

Replacing a Delta bathroom sink faucet cartridge is a straightforward task that can be completed in less than an hour. The cartridge is a small, cylindrical device that controls the flow of water through the faucet. Over time, the cartridge can become worn or damaged, causing the faucet to leak or drip. Replacing the cartridge is a simple way to restore the faucet to proper working order.

Tools and Materials You'll Need:

Philips head screwdriver
Adjustable wrench
New Delta faucet cartridge (specific to your faucet model)
Bucket or bowl
Cloth or rag

Step-by-Step Instructions:

1. Shut Off the Water Supply:
Locate the water shut-off valves beneath the sink and turn them off to stop the flow of water to the faucet.

2. Remove the Aerator:
Use an adjustable wrench to unscrew the aerator, which is usually located at the tip of the faucet. This will allow any remaining water to drain out.

3. Remove the Handle:
Locate the handle set screw and loosen it with a Philips head screwdriver. Remove the handle.

4. Remove the Escutcheon:
Beneath the handle, you'll find the escutcheon, which is a decorative plate covering the cartridge. Use an adjustable wrench to loosen and remove the escutcheon.

5. Remove the Cartridge:
Use an adjustable wrench to grip the cartridge and rotate it counterclockwise to remove it.

6. Install the New Cartridge:
Insert the new cartridge into the faucet body by aligning the splines on the cartridge with the grooves in the body. Rotate the cartridge clockwise to hand-tighten it.

7. Replace the Escutcheon:
Place the escutcheon back onto the faucet and tighten it with an adjustable wrench.

8. Replace the Handle:
Position the handle onto the cartridge and align the set screw holes. Tighten the handle set screw with a Philips head screwdriver.

9. Turn on the Water Supply:
Open the water shut-off valves beneath the sink to restore the flow of water to the faucet.

10. Test the Faucet:
Turn on the faucet and check for any leaks or dripping. If there are any leaks, further tightening of the cartridge or other components may be necessary.

Replacing a Delta bathroom sink faucet cartridge is a relatively simple and inexpensive repair that can restore the faucet to proper working order. By following these steps carefully, you can save time and money by doing it yourself.
