Tank to Mains Changeover / Aquasaver / Rainbank

Aquasaver

What is a Rains to Mains/Rainbank Changeover device?

Quite simply a Rains to Mains Changeover Device is a valve that harvest rainwater from a tank to be used for household application like toilets and laundry. This device will automatically switch to Mains Water Supply when it senses there is insufficient water in the tank.

Most Rains to Mains Changeover Devices will work with a pressure controller and will auto restart. There is no requirement for a float switch.

The devise is small in size, approximately 150mm long and 120mm high. They often sit on top of a pressure pump but they can also be positioned against a wall or other places that best suits the set up.

Benefits of an Aquasaver or Mains Changeover Device.

The main benefit of the Changeover valve is that it enables continuous flow of water. If the tank was using a pump without an Aquasaver or Changeover Device then the water supply would stop when the tank water is low.

Using water from a water tank will also save you dollars on your utility bills.

Probably the biggest benefit of using harvested rainwater is the responsible use of our most precious resource. Rather than rainwater being diverted to storm water, homeowners can store this water and use it for their own use. This could be to fill swimming pools, laundry, toilets, washing cars etc.

How do I know when I am using Tank Water vs Mains Water?

It’s simple – if the pump is working then you are using water that is stored in your tank. If the pump is not working then you are using Mains Water. This might be because there is insufficient water in the tank to service your needs.

Are there other names?

These valves can be know as many other names such as:

Aquasaver

Tanks to Mains Switchover

Mains Switchover

Rainbank

Diversion Valve
