 The back-flow stop valve automatically closes when water or sewage flows back through the drain system during flood conditions. The stop valve allows normal sewage flow from the inlet to the outlet side of the valve with absolutely no flow restriction. Integral stop points in the wing area plus built-in flow channels combine to direct the sewage through the valve protecting the gate from soil contamination caused by sewage flow beneath the gate.
In the event of sewage backflow, the back surge is diverted to the 45-degree wings on the gate causing an upward lifting action. Once the lift occurs, the flow of water slams the gate into the closed position, protecting the entire plumbing system from sewage back surge. The gate has polyethylene foam inserts, which will float the gate into the closed position in a slow reversal of sewage back surge.
The back-flow valve also has a built-in inspection cover to facilitate rodding of the main building drain.
