Developed in conjunction with the Department of Defense, the Wastop is a patented valve designed to prevent backflow in drains. In addition, it is also a clever way to help avoid odours from escaping your pipes. It is available in a variety of sizes. Some of the more common options include a flanged version for the most part, as well as a factory fitted model that can be run inline with your existing pipework.

The Wastop can be installed in virtually any type of pipe, including pvc and stainless steel. In fact, the company makes one for tidal outfalls, which can be installed inline with wastop your existing pipes. The patented membrane that comes with the product is especially effective at keeping water and odors out of your pipes.

The Wastop is also well suited to preventing backflow, but the true magic is in the specialized Memory Membrane that is housed inside the valve. This gizmo is what really sets it apart from the competition. The special elastomer material has the ability to maintain its shape while also providing some serious chemical resistance. The best part is, the Wastop can be easily installed in just a few minutes. And the nifty hat is that the WaStop can be mounted in a variety of ways, ranging from a chamber to a vertical installation. The company can even offer a special size for your specifications. It is a true water tight inline device that can resist up to 12 meteres of back pressure.
