The Wastop backflow valve has unique, patented construction that stops backflow in drains. Its design also prevents the infiltration of gases, flotsam, and insects. It also prevents odours from building up in pipelines. These are just a few of the many advantages of using a Wastop.
Inline non-return valve
The Wastop inline non-return valve is a revolutionary design, offering the best protection against flooding, backflow and odour control. This valve can be easily installed in existing pipework and is available for most pipe sizes up to 1800mm. AQUIKO also offers bespoke fittings for more specialised applications. Its patented Memory Membrane is a special elastomer that can be inserted inside the pipe, ensuring that it will open when required and seal immediately to prevent backflow.
Another unique feature of the Wastop is that it can be retrofitted, eliminating the need for digging a hole and cutting the pipe. This is a great way to save money, while eliminating the need to dig a new drain and deal with the mess that comes with it.
A Wastop backflow valve is a high-performance backflow prevention device that features an innovative flexible membrane that opens when forward flow passes under it, and closes when reverse flow fills it. WaStop is available in a wide range of sizes, from three to 72 inches. The valve complements the J&S HedFlex check valve, and is exclusively distributed in North America.
A Wastop inline check valve fits almost any type of pipe, and is easily accessible from ground level. It also offers the lowest headloss in the market and provides 100% backflow prevention. Its unique pulsating flow pattern also reduces maintenance costs.
Exceptional shape retention
A WaStop backflow valve is a device used to control backflow and prevent odours in drinking water systems. The WaStop valve is one of the most versatile backflow valves available today, and it has a number of benefits that make it the choice of many water utilities. Its patented memory membrane can be installed in both plastic and stainless steel pipes and is made from a specially formulated blend of elastomers for chemical resistance and exceptional shape retention. This site link means that the valve always opens when needed and seals immediately when backflow is detected.
The valve’s short travel distance allows it to be easily inserted into any existing pipe. This design also allows for fast closing without generating excessive pressure, which helps prevent water hammer.
Chemical resistance
The chemical resistance of a WaStop backflow valve is a key component of its effectiveness. The valve’s Memory Membrane, which can be made of stainless steel or plastic, is a special blend of elastomers that provides exceptional shape retention and chemical resistance. This elastomer allows the valve to always open when required and seal immediately if backflow occurs.
Installation requirements
The Wastop backflow valve is a highly effective way to prevent back flow, flooding, and sewage odors. This backflow valve can be installed easily in most plumbing systems and can be installed by a maintenance crew or an outside contractor. Its Memory Membrane is made from a specially formulated elastomer, which provides superior chemical resistance and shape retention. This ensures that when the Wastop is opened, it immediately seals to prevent backflow.
To ensure proper operation, wastop backflow valves should be installed at least six inches above the finished grade. They should also be mounted on a heat trace wire. Proper clearances and drainage requirements are also necessary for this application. Additionally, backflow assemblies should be installed in areas where they do not block natural or artificial light. Also, adequate security measures should be implemented when installing them.
