Is this a problem everywhere else in your house, too? If not, then you may have a Peerless® pressure balance valve. This valve contains an adjustable Rotational Limit Stop: a small plastic device designed to reduce the risk of scalding. You may adjust the temperature yourself. Just follow these instructions on adjusting the Rotational Limit Stop.
- Let the water run until both hot and cold water is fully mixed.
- Now rotate the handle fully counterclockwise, to the hottest position.
- Place a thermometer in a plastic tumbler, and hold the tumbler in the water stream.
- If the water temperature is above what your local plumbing code allows (110° F or 120° F), remove the handle or take off the temperature knob and rotate the rotational limit stop as follows:
- Turn the limit stop counterclockwise For every tooth the rotational limit stop is rotated counterclockwise, the maximum water temperature will decrease approximately 6° F. NOTE: If your water temperature is too cool, rotate the limit stop clockwise.
- Replace the handle. After verifying the water outlet temperature, secure the handle with the screw. Do not over tighten.
- MAKE SURE COLD WATER FLOWS FROM THE VALVE FIRST. ALSO MAKE SURE THAT YOUR WATER (AT ITS HOTTEST FLOW) DOES NOT EXCEED THE TEMPERATURE ALLOWED (see steps 1-4 above).
Important points to remember:
- See illustrations to reduce outlet temperature.
- Make sure cold water flows from the valve first and does not exceed 120 degrees Fahrenheit at the hottest flow.
- According to industry standards, the maximum allowable temperature of water exiting the valve should not exceed 120 degrees Fahrenheit. (Temperature may vary in your area.)
- After adjusting water temperature, place a thermometer in a plastic tumbler and hold the tumbler in the water stream to test the temperature. Do not test with hands or any body part.
- If your water supply or temperature is unacceptable throughout your house, you probably need to adjust the temperature on your water heater. We recommend you follow the instructions of your water heater manufacturer. Typically, water heaters should be set in the "moderate" range, especially if you have small children.
