Wastop membrane check valve for pp-/pvc pipes

Wastop membrane check valve for pp-/pvc pipes

Art. no.: 4281301

WaStop® is a revolutionary patented and certified check valve that installs in minutes in a pipe or drain. It can be installed horizontally or vertically in an intake or outlet. WaStop® is installed to prevent backflow. The flow in the main flow direction creates pressure against the membrane, which causes the membrane to open exactly as much as needed to allow the flow to pass unhindered. In case of backflow, the membrane fills with water or gas, acting as a plug in the pipe. WaStop® blocks all backflow in the pipe or drain. The WaStop® check valve can be configured to handle up to 12 metres back pressure.
