Materials You’ll Need:

Safety Precautions:

Before you begin, ensure your safety by turning off the water supply to your bathtub. Open the faucet to release any remaining water and wear gloves to protect your hands.

Step-by-Step Instructions:

1. Remove the Handle:

• Use the flathead screwdriver to remove the small screw holding the handle in place.
• Gently pull the handle straight toward you to detach it.

2. Access the Cartridge:

• Use the adjustable wrench to carefully unscrew the cap that covers the cartridge.
• Pull the old cartridge straight out of the faucet body.

3. Clean the Faucet Body:

• Use a rag or towel to remove any debris or old sealant from the faucet body.
• This will ensure a good seal for the new cartridge.

4. Install the New Cartridge:

• Align the new cartridge with the faucet body and insert it straight in.
• Push it firmly into place until it is seated properly.

5. Reattach the Cap:

• Screw the cap back onto the faucet body using the adjustable wrench.
• Tighten it securely, but avoid overtightening.

6. Reinstall the Handle:

• Secure it with the screw you removed earlier.

7. Turn on the Water:

• Turn on the water supply to your bathtub and check for any leaks around the cartridge.
• If there are no leaks, your faucet is now fully functional.

Tips for Success:

• Use a cartridge that matches the make and model of your faucet.
• If your faucet has two handles, replace both cartridges at the same time.
• Apply a small amount of plumber’s grease to the O-rings on the new cartridge for a better seal.
• If you encounter any difficulty removing the old cartridge, try using a pair of pliers to gently pry it out.

Troubleshooting:

• Leaking cartridge: Ensure the cartridge is fully seated and the cap is securely tightened. If the leak persists, replace the cartridge again.
• Faucet not turning on: Make sure the water supply is turned on and that the cartridge is properly installed.
