Wastop Backflow Valve Memory Membrane

The Memory Membrane inside a Wastop backflow valve is a key feature to the valve’s effectiveness. Made from a specially formulated elastomer with superior chemical and shape retention, it ensures the valve is always open when it’s needed to stop backflow. And the best part is that it seals immediately, too.

The Wastop backflow valve is a patented design that works by keeping water in and waste water out. Its patented construction prevents backflow, prevents flooding, and minimizes sewage odors. The valve is very easy to install and can be inserted into virtually any type of pipe.

The elastomer sleeving in the valve provides maximum flow capability and minimizes pressure drop across the valve. This design eliminates the need for frequent maintenance of conventional check valves. Additionally, the elastomer sleece can be made in a variety of styles, including slack-fit and reinforced versions.

Memory Membrane

WaStop backflow valves feature an innovative flexible membrane that opens when forward flow moves over it and closes when reverse flow fills the membrane. They are available in sizes ranging from three inches to 72 inches. For complete backflow prevention, the valve is complemented by a J&S HedFlex check valve. J&S is the exclusive distributor of WaStop in the North American market.

The Wastop backflow valves consist of a stainless steel pipe and elastomer sleeve. The sleeve is made of a specially formulated elastomer that possesses exceptional shape retention and chemical resistance. ThisĀ discover this special feature ensures that the valve always opens when water flows into the inlet side, sealing immediately when the flow is stopped.

Wastop backflow valves are one of the most effective backflow prevention devices available. Their unique patented construction keeps water and sewage out of drains and pipes and provides flood and odour protection. Plus, they prevent flotsam, insects, and other debris from entering the pipeline.

Wastop backflow valves use a specialized Memory Membrane that is inserted inside PVC and stainless steel pipes. It is made from a specially formulated elastomer that offers outstanding shape retention and chemical resistance. This innovative backflow prevention system guarantees the valve will always open and seal instantly when needed.

Chemical resistance

WaStop backflow valves use a specialized Memory Membrane, which is composed of an elastomer material that provides exceptional shape retention and chemical resistance. The membrane can withstand pressures of up to 12 meters, and is able to close immediately in the event of back flow.

This type of valve is inserted into almost any existing pipe. It is designed to work in inlet and outlet applications and can be installed horizontally or vertically, depending on the requirements of the installation. The valves can be installed using flanges.

Flood prevention

The unique patented construction of the Wastop backflow valve prevents backflow from drains and pipes. Not only does this prevent floods from occurring, but it also prevents sewage and odour from spreading. The valve is easy to install and can be placed in any type of pipeline.

The Wastop backflow valve is one of the most advanced in the industry. This Swedish product is available in a variety of sizes to fit most pipe types. It uses differential pressure to prevent backflow and does not require electricity or constant maintenance. It is able to withstand up to 12 meters of back pressure. It has the lowest headloss of any other valve on the market, and is 100% effective at preventing backflow. Its unique pulsating flow also helps keep pipes clean.
