Sparco whole house: Anti-scald Thermostatic Mixing Valve - Aquamix
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.

Anti-Scald Mixing Valve (by Legend)

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.

The manufacturer specifies that installation and maintenance should only be performed by a qualified plumber, and they recommend an in-line filter such as a wye-strainer installed before this valve.

1/2" Tempera Automatic Pressure Compensating Valve
by Precision Plumbing Products (PPP)
Pressure compensating valve TRB-2 = $89.59
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.

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.

sudden fluctuations? "While taking a shower, sometimes the water temperature changes. Why does this happen and how can I prevent it?"
This generally happens when someone uses water from the same water system (for example when flushing a toilet or using the kitchen faucet), at the same time. This causes changes in your pressure in the water line feeding your shower faucet. When you have changes in pressure on one side and not the other, you will feel the result of different volumes of hot versus cold water. To solve this problem, you can either install/increase your water piping sizes (which will help a lot in having less pressure fluctuations), or install a pressure balance device on the hot and cold water that feeds the shower faucet. This device detects changes in pressure and automatically balances it. You can also replace the shower faucet with a pressure balance faucet. If none of these are an option, you may want to purchase a scald protector to reduce your chance of getting scalded, but you would still be subject to temperature fluctuations.

"When installing the anti-scalding mixing valves are there any other helpful hints?"
We feel that whenever you install an anti-scald mixing valve after the water heater that you also install a check valve on the cold side, an in-line screen (such as a wye-strainer) and an expansion tank.

low pressure? "I have low water pressure, can I use these products?"
ALL of the products on this page will reduce your pressure even more. These anti-scald devices do reduce the pressure as they have friction loss, etc. If your water system is marginal and you cannot have less water pressure, then these products are not for you.

We offer many thoughts (quotes) to ponder, such as:
