  WaStop® - The Original Inline Check Valve  
       
  The patented Wastop® inline check valve has been the innovator and industry leader since its inception in 2002. 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, Wasto®p can be mounted horizontally, vertically, on an inlet, outlet, in a chamber, or utilizing flanges. Installation is a breeze!
