Full Product Details

Graf anti-backflow damper is an ideal way of preventing ground or surface water from getting back into the rainwater tank and contaminating your clean rainwater. Use if the location is subject to flooding or backflow from drain or soakaway.

Cube-shaped heavy-duty plastic with cover secured by four finger nuts. The cylindrical chamber is NOT part of the product and is shown here to demonstrate a possible application. The non-return valve can also be connected to the outlet of the u-tube siphon exit on the Graf Carat range of tanks, but ensure it is protected from earth movement.
