Fully electronic pumps designed for domestic water supply for urban and rural water storage tanks. Designed completely from nonferrous materials to avoid the effects of corrosion. Automatic electronic pump control provides constant pressure at low to full flows and provides dry run protection. The auto restart looks for water if the pump runs out. Automatic control incorporates electrical surge protection, rotatable pump connection and in-built check valve.

The pump is a surface mounted pressure system pump supplied ready to install. The unit is ideal for flooded suction and can handle suction lifts to 3m.

Bianco Rainsaver MK5 Mains Switchover

The Rainsaver MK5 replaces all changeover devices switches your system between tank water and town/mains water supply. The system is switched hydraulically, thus requiring no power, and is the least likely system to fail. It also requires the least amount of installation time, saving you time and money. The Bianco Rainsaver MK5 delimits your mains water supply to 200kPa. As long as the pump can supply water greater than 200kPa, which our selected pumps do, it will output tank water. When the water in the tank is insufficient to supply the system, mains water supply is delivered to the home at 200kPa.

There is a pressure drop during the time the system is using mains water supply. The max mains pressure you will get is 200kPa to those taps to which the system is connected. This is normally just the toilets and a couple of outdoor taps. Once the water level in the tanks increases, the system will automatically return to tank supply at full power once again.

As a guide, in Melbourne and Sydney, mains water at the home is between 380 and 600kPa.
