The Evolution MkIII comes as an integrated unit with a Grundfos SB Submersible Pump and PM Rain Controller. Evolution MkIII offers the advantage of dramatically reducing installation time and saving costs, while improving the appearance of the water tank system for the home owner. When the tank runs out of water or when there’s a power outage the PM Rain controller will automatically open the main line to the internal appliances.
