APPLICATION 
The RainAid® valve is designed to be connected to the mains water supply on a rainwater collection tank. It will provide a backup supply of water in the event of demand exceeding rain supply. 
 
HOW IT WORKS 
Under normal conditions, rainwater will fill the tank. If the rainwater level drops below a pre-set level, the RainAid® valve will open to maintain the water level using the mains water supply. 
The rainwater tank is used to supply water to non potable outlets such as the toilets, laundry and garden. There is a 100mm (4”) differential between the open and closed positions of the RainAid® Valve.
