The Rainsaver MK3E

The Rainsaver MK3E is an electronic water tank / mains water change over device that automatically switches between tank water and the main supply. Not only does it help conserve water but it helps conserve energy too because it’s easy to install.

The Rainsaver MK3E provides mains back up for Pressure Pump supply systems. The Rainsaver MK3E can be purchased separately and fitted to any brand of independently controlled, electronic or pressure switch operated pump pressure system (can be used with a pump fitted either with a presscontrol or with a pressure switch and airtank).

The Rainsaver works as follows: when there is rainwater in the tank, the MK3E runs on tank water. When the tank water runs out, the MKIIIe will automatically switch to mains water. When the tank fills again with rainwater, the MKIIIe will automatically switch back to tank water.

The Rainsaver MK3E changeover device supplies clean rainwater from a rainwater tank via an automatic pressure system pump to toilets, laundry and garden taps in a household. Mains water is also connected to the RainsaverMK3E as an automatic back up should rain water level be too low, or if there is a power or pump* failure. (*Should there be a pump failure, mains back up is achieved by turning the RainsaverMK3E off at the power point.) 

The Rainsaver MKIIIE is designed to operate with pumps up to 800kPa and will allow for up to 100 Litres per minute of flow. The low voltage float switch supplied prevents the pump from running dry and allows automatic switch over to mains supply should the rain water level in the tank be too low.
