How to Replace the Cartridge in a Delta Bathroom Sink Faucet

Leaking or malfunctioning faucets are a common annoyance in any home. When it comes to Delta bathroom sink faucets, replacing the cartridge is often the solution to restore proper function. Here's a detailed guide to help you through the process.

Gathering Materials:

Before you begin, gather the following tools and materials:

Allen wrench or hex key (typically included with the faucet)
Replacement cartridge (specific to your Delta faucet model)
Bucket or bowl for collecting excess water
Cloth or sponge for cleaning

Step-by-Step Instructions:

1. Turn Off Water Supply: Begin by locating the water supply valves beneath the sink. Turn off both the hot and cold valves completely to prevent water flow.

2. Release Handle: Using the Allen wrench, loosen the screw located on the base of the handle. Gently lift and remove the handle.

3. Unscrew Escutcheon: Remove the cap or escutcheon covering the base of the faucet. This usually requires turning it counterclockwise.

4. Loosen Cartridge Nut: Beneath the escutcheon, you'll find a cartridge nut. Use the Allen wrench to loosen and remove the nut.

5. Extract Old Cartridge: Carefully grasp the old cartridge by its base and pull it straight up to remove it.

6. Clean Components: Clean the faucet base and the inside of the escutcheon to remove any debris or buildup.

7. Install New Cartridge: Insert the new cartridge into the faucet base, aligning the splines or threads. Gently push it down until it seats firmly.

8. Tighten Cartridge Nut: Thread the cartridge nut back onto the faucet base and tighten it securely with the Allen wrench.

9. Reassemble Handle and Escutcheon: Place the escutcheon over the faucet base and turn it clockwise to secure it. Replace the handle and tighten the screw with the Allen wrench.

10. Restore Water Supply: Turn on the water supply valves beneath the sink and check for any leaks.

Tips:

For optimal performance, replace the cartridge with an original Delta replacement part.
If you encounter any difficulties during the process, refer to your Delta faucet's owner's manual or consult a professional plumber.

By following these steps, you can effectively replace the cartridge in your Delta bathroom sink faucet and restore its functionality.
