Adjust Anti-Scald Feature (Optional)

What happens here

If desired, adjust the anti-scald feature on the Kohler valve. This is typically a red knob with an Allen wrench adjustment screw on the cartridge. To allow for more hot water, back the screw out. To limit the maximum hot water temperature (a safety feature useful for households with children or elderly), tighten the screw. This adjustment is performed on the cartridge itself, usually before the handle is fully reinstalled.

Goal: Set desired maximum hot water temperature for safety and comfort.
