Step-by-Step Repair Instructions

1. Turn Off the Water Supply

Before you begin any repairs, it is important to turn off the water supply to the faucet. This can be done by closing the shut-off valves located under the sink. If there are no shut-off valves, you will need to turn off the main water supply to your home.

2. Remove the Handle

Once the water supply is turned off, you can remove the handle from the faucet. Most Delta one handle bathroom faucets have a small set screw located on the bottom of the handle. Use a Phillips head screwdriver to remove the set screw, then pull the handle straight up to remove it.

3. Remove the Cartridge

Once the handle is removed, you will be able to see the cartridge. The cartridge is a cylindrical component that contains the internal components of the faucet. To remove the cartridge, use an adjustable wrench to loosen the retaining nut that holds it in place. Once the retaining nut is loose, you can pull the cartridge straight out of the faucet body.

4. Inspect the Cartridge

Once the cartridge is removed, inspect it for any damage or wear. If the cartridge is damaged or worn, it will need to be replaced. You can purchase a replacement cartridge at your local hardware store or online.

5. Install the New Cartridge

If the cartridge needs to be replaced, insert the new cartridge into the faucet body. Make sure that the cartridge is properly seated, then tighten the retaining nut until it is snug. Do not overtighten the retaining nut, as this could damage the cartridge.

6. Reinstall the Handle

Once the cartridge is installed, you can reinstall the handle. Insert the handle onto the faucet body and tighten the set screw until it is snug. Do not overtighten the set screw, as this could damage the handle.

7. Turn On the Water Supply

Once the handle is reinstalled, turn on the water supply to the faucet. Check for any leaks. If there are no leaks, your Delta one handle bathroom faucet is now repaired and ready to use.
