The WaStop Inline Non Return Valve has an ingenious design. Therefore, this design ensures you are provided with the best possible protection against backflow, flooding and odour control.
Sizes are available to fit most sizes of pipes up to 1800mm. However, where more bespoke fittings are required contact AQUIKO and we will be able to assist.
Due to the unique way in which it works with differential pressure it works autonomously. Therefore, there is no need for human interaction or electricity. In conclusion, without the need for constant maintenance, the WaStop just works!

Description

THE INGENIOUS WASTOP® INLINE CHECK VALVE

  • Quick and Easy to install, at any angle
  • No mechanically moving parts
  • Low head losses
  • Virtually maintenance-free
  • Resistant to blockage

The WaStop ® inline check valve is a simple yet highly effective design. Using very few components. Ensuring reliable performance with virtually no input once installed.

Installation can be into, between, or at the end of pipes in a variety of ways. Ideal for retrofit into existing systems as it can be installed at any angle. In the majority of cases, it is installed by pushing into place, and secured with either bolts or flexible coupling. Therefore, very quick protection from flooding.

The unique membrane design of the WaStop ® inline check valve ensures positive closure when no flow is present. Meaning very little head is required to open it. Therefore, the activation point of the valve is relatively low. The flushing action clears debris when it activates. In other words, it’s a device you can depend on.

As the membrane pops open, a sudden rush of water passes through it clearing downstream debris. As the water is discharged the membrane pops closed. Reducing the likelihood of debris getting trapped in the gap.

 

LOW HEAD LOSS

 

When compared to flap valves or duckbills the WaStop® requires much less head to open. Therefore, in many cases, a smaller valve and smaller diameter pipework can achieve the same result. For example, a WaStop® of 215mm can achieve the same head-loss as a typical duckbill of over 300mm. Reducing the diameter of the pipe, handling issues and excavation costs means the overall cost is much lower.

 

MULTIPLE USES OF THE WASTOP®

 

Usually used for prevention of backflow in water pipes. In addition, it is also often used for odour protection. Ideal for ceilings of sewers drains from cellars and air release in offshore pipelines. Where there is no headwall present it can also be used vertically.

AQUIKO are stockists of the WaStop®. For pipe diameter up to 600mm quick dispatch is available. We also regularly supply custom-built WaStops® for pipes up to and including 1500mm diameter. Please contact us for more details.

WaStop ® inline check valve is available as:

  • PVC- for connection to standard PVC pipe, using off the shelf push-fit couplings.
  • Stainless Steel (304 or 316) housing, with various fitting types:
    • Insertion into the pipe, wall fixing or flexible coupling
    • Inline connection, using flexible couplings
    • Flanged connection (1 or 2)
