3. Safety Information

Always prioritize safety when working with plumbing. Failure to follow these guidelines may result in property damage or personal injury.

• Turn off Water Supply: Before beginning any work, locate and turn off the main water supply to the faucet or the entire building.
• Depressurize Lines: Open the faucet to drain any remaining water and relieve pressure in the lines.
• Wear Protective Gear: Use appropriate personal protective equipment, such as safety glasses and gloves.
• Use Correct Tools: Ensure you have the necessary tools for the job and use them correctly.
• Consult a Professional: If you are unsure about any step, consult a qualified plumber.

4. Installation Instructions

This section outlines the general steps for replacing the right-hand stem and handle. Specific faucet designs may vary, but the core process remains similar.

1. Prepare the Work Area: Ensure the water supply is off and the faucet is depressurized. Clear the area around the faucet.
2. Remove Old Handle:
   • Carefully pry off the index button (hot/cold indicator) from the top of the handle.
   • Unscrew the handle screw located underneath the index button.
   • Remove the old lever handle.
3. Remove Old Stem Assembly:
   • Using an adjustable wrench, carefully unscrew the bonnet nut that secures the stem assembly to the faucet body.
   • Extract the old stem assembly, including the stem, packing, washers, spring, and check valve. Note the order of components for reassembly.
4. Clean Faucet Body: Clean any debris or mineral deposits from the faucet body opening where the stem assembly sits.
5. Assemble New Stem:
   • Apply a small amount of the provided lubricant to the new packing and O-rings (if applicable).
   • Assemble the new check valve, spring, stem, packing, and retainers in the correct order, mirroring the old assembly.
6. Install New Stem Assembly:
   • Insert the newly assembled stem into the faucet body.
   • Thread the new bonnet nut onto the faucet body and tighten it securely with an adjustable wrench. Do not overtighten.
7. Install New Handle:
   • Place the new lever handle onto the stem.
   • Secure the handle with the new screw.
   • Press the new index button (red for hot) into place on top of the handle.
8. Test for Leaks: Slowly turn the main water supply back on. Check for any leaks around the newly installed stem and handle. Operate the handle to ensure smooth function. If leaks occur, gently tighten the bonnet nut or recheck component assembly.

5. Operation

Once installed, the right-hand handle controls the hot water flow. Rotate the lever handle to open or close the water supply. The check valve ensures water flows in one direction, preventing backflow.

6. Maintenance

Regular maintenance can extend the life of your faucet components.

• Periodic Inspection: Periodically check the handle and stem for signs of wear, stiffness, or leaks.
• Lubrication: If the handle becomes stiff, turn off the water supply and apply a small amount of plumbing-grade lubricant to the stem's moving parts.
• Component Replacement: If leaks persist or the handle does not operate smoothly after lubrication, it may be time to replace the stem and handle components again using a new service kit.

7. Troubleshooting

Common issues and their potential solutions:

• Leaking from Handle Base:
  • Ensure the bonnet nut is tightened correctly (do not overtighten).
  • Verify that the packing and washers are correctly seated and not damaged.
• Stiff Handle Operation:
  • Apply plumbing lubricant to the stem.
  • Check for mineral buildup that might be impeding movement.
• No Water Flow:
  • Confirm the main water supply is fully open.
  • Check if the check valve is installed correctly and not obstructed.
