Step-by-Step Replacement Guide

1. Remove the Handle and Escutcheon:

• Use a Phillips head screwdriver to remove the screws holding the handle in place.
• Pull off the handle and set it aside.
• Pry off the escutcheon (decorative plate) covering the valve stem using a flathead screwdriver or putty knife.

2. Unscrew the Packing Nut:

• Locate the packing nut, which is usually a large hexagonal nut behind the escutcheon.
• Use an adjustable wrench to loosen and remove the packing nut.

3. Remove the Valve Stem:

• Pull out the valve stem from the valve body.
• Note the orientation of the valve stem and any O-rings or washers attached to it.

4. Inspect the Valve Seat:

• Check the valve seat (where the valve stem fits) for any debris or damage.
• Clean the valve seat thoroughly using a rag or brush.

5. Install the New Valve Cartridge:

• Take the new valve cartridge and align it with the valve seat.
• Insert the cartridge into the valve body and gently push it in until it fits snugly.

6. Reassemble the Valve:

• Replace the valve stem, ensuring it’s aligned correctly.
• Tighten the packing nut by hand until it’s snug.
• Use an adjustable wrench to further tighten the packing nut, being careful not to overtighten.

7. Reattach the Escutcheon and Handle:

• Place the escutcheon back over the valve stem and secure it with screws.
• Reinstall the handle and tighten the screws.

Tips for a Successful Replacement

• Use plumber’s tape on the threads of the packing nut to prevent leaks.
• If you encounter any resistance while removing or installing components, do not force it.
• If you’re unsure about any step, consult a professional plumber.

Troubleshooting Common Issues

• Leaking from the handle: Tighten the packing nut further or replace the O-rings on the valve stem.
• No water flow: Ensure the water supply is turned on and the cartridge is installed correctly.
• Handle stuck or loose: Check for damaged O-rings or washers on the valve stem and replace them if necessary.
