The Gravity System is ideal for domestic applications. It has a major advantage in that in the event of a power failure on site (or the rain stocks running dry) the system will automatically switch to mains water supply to ensure a continuity of service.
The gravity system requires a header tank to complete the package. Kingspanwater supply a header tank as an optional extra which contains two independent valves operating both the mains and rainwater supply (we recommend a Kingspanwater header tank is used). The water from the header tank will flow by gravity to the serviced appliances. The system will always draw from the rainwater supply first.
