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