Troubleshooting
Faucet still drips after replacement.
Ensure the valve was installed correctly and the bonnet nut is sufficiently tightened. Check the valve seat for any debris or damage that may prevent a proper seal. If the issue persists, the faucet body itself might be compromised.
Handle is difficult to turn.
Verify that the bonnet nut is not over-tightened. Ensure no debris is present around the valve stem. If the valve is new, it might require a few more uses to break in.
Water leaks around the handle base.
Check that the bonnet nut is tightened correctly. If the leak persists, the O-rings or packing within the valve stem assembly may need replacement, or the valve itself may be faulty.
Valve does not fit.
Double-check the manufacturing date of your faucet and confirm it is within the 1990-2010 range for Kohler two-handle models. Ensure you are not attempting to use this valve as an upgrade for a different valve type.
