Wastop excels at preventing backflow, flooding, and sewage odor spread in pipe networks. It can be inserted into almost any existing pipe. Unlike any other check valve available today, Wastop® can be mounted horizontally,vertically, on an inlet, outlet, in a chamber, or utilizing flanges. Installation is a breeze!.
For over 14 years Wastop has been leading with the lowest headloss in the industry. The secret to Wastop®’s effectiveness is its specialized Memory Membrane, inserted inside either stainless steel or pvc pipes depending on the application. The Memory Membrane is constructed of a specially formulated blend of elastomer which gives it exceptional shape retention and chemical resistance. This ensures Wastop® always opens when needed, but then immediately seals to prevent backflow.
