RainBank® by Davey Products forms the heart of an efficient rainwater harvesting system. It offers continuous supply of rainwater for toilets, gardens and laundry, only using mains water as a backup. RainBank® can provide water savings of up to 40% as well as energy savings.

When water is required, RainBank® checks to see if stored rainwater is available. If there is water available, RainBank® switches on the water pump, allowing rainwater to flow. When finished, RainBank® switches off the pump, and waits for another water demand.

When the rainwater supply is exhausted, RainBank® switches off the pump, returning to mains supply. RainBank® does not consume power while on standby.
