Scald protection devices are a must in homes with young children, the elderly and physically challenged individuals - but are recommended for every home and may even be code in some areas. While caution is always first and foremost with regards to scald prevention, scald protection devices can help to maintain safer water temperatures.

Whole House Anti-scald Thermostatic Mixing Valve Aquamix Valve by Sparco

These units are to be installed in a hot water line and require a cold-water feed. They also requires a swing check valve on the cold water feed line to prevent hot water from entering the cold water system. We also recommend a hot water expansion tank when you install these types pf valves to prevent excessive pressure on the hot water side (due to hot water expansion). These types are best installed right at your water heater.

According to the manufacturer, this valve maintains a constant water temperature, preventing scalding water from reaching end-point devices in domestic water installations. There are three adjustable (100°, 110°, 120° F) settings on this unit, which automatically regulates domestic water temperatures at fixtures by combining both hot and cold water and by reducing hot water flow if the cold water is shut off.

1/2" Tempera Automatic Pressure Compensating Valve By Precision Plumbing Products (PPP)

The Tempera valve is a highly sensitive pressure balancing valve that holds a selected water temperature to within one degree regardless of incoming pressure changes. It responds within milliseconds to pressure loss on either hot or cold sides. It is normally installed between the hot and cold supplies and a shower valve. Tempera valves may be installed in any position or at any angle. When installing a Tempera valve, be sure to leave a way to access the valve if maintenance is required. Note: The TRB-2 valve is not compatible with the Moen Chateau series single control mixing valves. To see more pictures of the Tempera and a typical installation, click here

Fact Sheet
What you should know about hot water injuries:
The Scalding Truth

Hot water scalds account for 20% of all burns. More than 2,000 American children are treated for scalds each year. Scalding accidents occur most frequently in the bathrooms and kitchens where they are most preventable. Scalding leads to additional injuries such as heart attacks, shock, falls, and serious broken bones, particularly among the elderly. Scalding and other burns require the most expensive treatments: long hospital stays, costly skin grafts, and plastic surgery. Most U.S. states now mandate some form of anti-scald measures in building codes. The International Association of Plumbing and Mechanical Officials have amended the Uniform Plumbing Code to require anti-scald protection. A bathroom sink and shower can be fitted with anti-scald protective devices for very little money. Given current technology, hot water injuries can be virtually eliminated in the house.

ALL brands of man-made mechanical devices WILL (eventually) fail. The scald protection devices offered below are all mechanical devices, and therefore, it's best to design your hot water systems to not rely on these (or any) devices as your first defense against scalding.
