Automatically blends the hot and cold water feed lines to control discharge to an acceptable and safe
temperature. This also increases the amount of hot water that is drawn from the solar water heater by not
allowing the incoming water to fully temper the hot water stored inside the tank.
Ball Valve (for cold water shut-off) (Valve #24)
The cold water shut off valve should be used in the event of an emergency shutdown.

may damage your water heater.
