Water is a valuable resource, and saving water is a priority for every Australian household. To make water saving easy Onga has developed WaterSwitch. WaterSwitch is a dual source value that utilises water captured within a rainwater tank tosupply water requirements around the home. Not all domestic water applications and appliances require waterthat has been treated for drinking by a local water authority. Uses for rainwater include, washing machines, toilets flushing, and garden watering. With WaterSwitch your customers will save water automatically.

HOW DOES WATERSWITCH WORK?

WaterSwitch is a fully automatic device that has the ability to detect the availability of water inside the tank (via a float sensor) so that it can ensure a seamless supply of water to the home without any interruption. When the tank contains water the float sensor relays this to the WaterSwitch and the WaterSwitch will automatically divert the demand to be supplied with the available rainwater. In the event that the rainwater falls below the set level of the float sensor the

WaterSwitch seamlessly switches all demand on the system over to the mains water to ensure that supply of water isnever interrupted and that your customer is maximising their use of rainwater and therefore maximising their savings.

WHY IS WATERSWITCH THE BEST SOLUTION FOR URBAN RAINWATER?

WaterSwitch is a unique system that was designed to avoid high losses in pressure, which means WaterSwitch can be used in a broader range of applications like garden irrigation including pop up sprinklers. The high flow design of the WaterSwitch enables Onga to provide the most effective pump package, providing optimum energy efficiency and lower running costs. On top of the sophisticated design of the unit Onga has also thought of a range of additional features thatmake WaterSwitch so much easier to use.

These extras include:

• Energy savings - The pump only operates when rain water is being used
• Low pressure drop design - More water, more pressure from either pump or mains supply
• Display panel - See which water source is being used at any given time
• Override control - Allows the homeowner to use tank water if mains shut off.
• Backflow protection - A dual check valve provides backflow prevention to keep rain water and the mains supply separated
• Pump check valve - This prevents precious mains supply water from escaping through the rain water tank
• Solenoid valve operation - Does not mix water - allows either mains or tank water to be used. If power is unavailable, Waterswitch lets main water pass to appliances.
