Grundfos JPC4-47 with PMRain Water Switch Pump

The PM Rain automatically starts when a water demand is detected, for example the flushing of a toilet or filling of a washing machine, and will switch over to mains water supply when the rainwater tank is empty or in case of an electrical failure.

The PM Rain eliminates the need for a level sensor in the tank, which drastically reduces installation time and costs.
