4. Setup & Installation

Follow these steps to install the KOHLER K-87466 Extension Stem:

1. Prepare the Work Area: Clear the area around the faucet. Place a towel or cloth in the sink basin to catch any drips or dropped parts.
2. Shut Off Water Supply: Locate the water supply valves under the sink and turn them clockwise until fully closed. Turn on the faucet to drain any remaining water and confirm the supply is off.
3. Remove Faucet Handle and Trim: Carefully remove the faucet handle and any decorative trim to expose the existing faucet stem. This usually involves unscrewing a set screw or prying off a cap. Refer to your faucet's specific instructions if needed.
4. Access Existing Faucet Stem: Once the handle and trim are removed, the top of the existing faucet stem should be visible.
5. Attach Extension Stem: Align the KOHLER K-87466 Extension Stem with the top of the existing faucet stem. The extension stem is designed to fit securely onto the existing stem. Gently push and twist until it seats properly. Ensure a snug fit. If desired, apply a small amount of plumber's tape to the threads for an extra seal, though it may not be necessary for this type of connection.
6. Reassemble Faucet: Carefully reattach the faucet handle and any decorative trim in reverse order of removal. Ensure all components are secure but do not overtighten.
7. Restore Water Supply: Slowly turn the water supply valves counter-clockwise to open them.
8. Check for Leaks: Turn on the faucet and inspect all connections for any signs of leaks. If leaks are detected, shut off the water supply, re-check the connections, and tighten as necessary.

5. Operation

The KOHLER K-87466 Extension Stem is a passive component that functions by increasing the effective height of your faucet's internal stem. Once installed, it allows for the proper reattachment and operation of your faucet handle at an elevated position, providing additional clearance or accommodating specific faucet designs. No special operational steps are required beyond the normal use of your faucet.

6. Maintenance

The KOHLER K-87466 Extension Stem requires minimal maintenance. To ensure its longevity and proper function:

• Cleaning: Clean the visible parts of the extension stem (if exposed) with a soft cloth and mild, non-abrasive soap and water. Rinse thoroughly and dry.
• Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or material of the stem.
• Regular Inspection: Periodically check the faucet assembly for any signs of leaks or loose connections. Address any issues promptly.

7. Troubleshooting

If you encounter issues after installing the extension stem, consider the following:

• Leakage at Faucet Base:
  • Ensure all connections are tightened properly.
  • Verify that the extension stem is fully seated onto the existing faucet stem.
  • If applicable, reapply plumber's tape to threaded connections.
• Faucet Handle Not Operating Smoothly:
  • Check that the faucet handle is correctly aligned and secured to the extension stem.
  • Ensure no internal components are binding or misaligned.
• Extension Stem Does Not Fit:
  • Confirm that your faucet uses genuine Kohler parts and is compatible with the K-87466 extension stem. This product is designed to work only with Kohler parts.

If problems persist, contact Kohler customer support or a qualified plumber.
