Moen's anti-scald faucets allow you to manually control the maximum temperature of your shower water. This feature is ideal if you have small children in your home and are worried about them turning on the shower and burning themselves. Adjusting and setting the temperature on your single-handle shower faucet is a simple do-it-yourself job.
Unscrew the nut on the bottom of your shower handle with an Allen wrench.
Move the dial on the front of the stem either clockwise or counterclockwise, depending on how you want to adjust the water temperature. Moving it counterclockwise will lower the temperature.
Set the handle back on the stem and tighten the Allen nut, securing the handle in place.
