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.

Optional Extra on the Header Tank

When ordering your system to make the gravity system complete you will require a header tank. KingspanWater offers a header tank with weir and double ballcock which allows the switch over to mains, the weir provides the mandatory air gap.
