We removed the old hot water unit, and raised the level under the new copper safe waste tray.
We installed the new 50 liter Rheem hot water unit with a new tempering valve, isolation valve, copper safe waste tray and a new Mildred solenoid valve.
The Mildred valve is installed on the cold water inlet to the hot water unit, which is battery operated and has a sensor that sits in the safe waste tray. When the sensor touches water, it shuts of the water supply to the hot water unit to prevent flooding.
This is ideal for units or houses where it is impractical to drain to outside or drainage.
