Step-by-Step Instructions

2. Remove the Escutcheon Plate

• Use a flathead screwdriver to gently pry the escutcheon plate (the decorative cover around the base of the faucet) away from the wall.

3. Remove the Cartridge or Valve Stem

• Most modern faucets use a cartridge that can be removed by hand. Simply unscrew it counterclockwise.
• Older faucets may have a valve stem that needs to be removed using an adjustable wrench.

4. Clean the Faucet Body

• Remove any debris or old sealant from the faucet body using a rag or towel.

5. Apply Plumber’s Putty or Teflon Tape

• Apply a thin bead of plumber’s putty or wrap a few layers of Teflon tape around the threads of the new cartridge or valve stem.

6. Install the New Cartridge or Valve Stem

• Screw the new cartridge or valve stem into the faucet body by hand.
• Tighten it further using an adjustable wrench, being careful not to overtighten.

7. Reinstall the Escutcheon Plate

• Place the escutcheon plate back over the faucet body and secure it with screws.

8. Reinstall the Faucet Handle

• Place the faucet handle back on the stem and secure it with screws.

9. Turn on the Water Supply

• Slowly turn on the water supply to the shower.
• Check for any leaks around the faucet.

10. Apply Joint Compound or Silicone Caulk

• If there are any gaps between the faucet and the wall, apply a thin bead of joint compound or silicone caulk to seal them.

Troubleshooting

• Faucet is leaking: Check if the cartridge or valve stem is installed correctly and tightened properly. Also, inspect the escutcheon plate for any cracks or gaps.
