Consumer Guide

Using anti-scald valves allows water in the hot water tank to be kept at higher temperatures, reducing the risk of Legionella bacteria and delivering the tap water at lower, safer temperatures.

There are several types of anti-scald valves, each with its own pros and cons. The do-it-yourself screw-on valve can be installed at the faucet or showerhead to reduce scalding water to a trickle. This protects against burns, but the sudden shut-off of the water flow may be confusing to a person with Alzheimer's or other types of dementia. Moreover, the water needs to be properly remixed before the water resumes flowing.

A better solution is the second type of valve, which installs directly on the water pipe. This type of valve can be installed directly on the pipes at sinks and bathing areas, mixing cool and hot water in the pipe before the water flows out of the faucet. Or, if you have access to the water heater in a single-family home, you can install a scald valve for the entire house.

Selecting the right valves for scald protection depends on your budget, your individual needs, and the size of the home. See our consumer guide for more information, including product resources, and talk to your plumber to discuss what is best for your situation.
