Bianco BIA-RAINSAVERMK4E Tank/Mains Changeover


Bianco BIA-RAINSAVERMK4E Tank/Mains Changeover

The Rainsaver MK4e replaces all changeover devices including the Davey Rainbank and Onga Waterswitch and converts manual pumps to a fully automatic mains and tank water changeover device in a jiffy. The changeover device is suitable for mains and pump flows up to 100 litres per minute and mains and pump pressure of 800kPa. The MK4e is suitable for pumps up to 1.1kW running on a 240V system and includes a plug and play power connection. You will still require to buy a pressure controller when replacing a Davey Rainbank and Onga Waterswitch, as these units have them built in. If the change-over device you are changing has a separate pressure controller that is functional, then you will not require a new pressure controller.
