WaStop® Inline Check valve

Area of use: Flood protection Pests & Odors
Wastop Backventil

The WaStop Inline Check Valve immediately protects people and properties from flooding caused by backflow. WaStop also protects against odour and pests in the sewer and stormwater systems. WaStop is ingenious in its simplicity

Ingeniously simple

WaStop is a fully automated solution that works without any human interaction at all. 

Thanks to the product’s use of differential pressure, neither electricity nor human intervention are necessary for continuous operation. The solution is available as standard for pipe NPS 3" - NPS 84"/DN75-2000

The solution protects against: 

  • Flooding caused by backflow
  • Odour 
  • Pests

Some advantages of the solution: 

  • Works immediately and automatically
  • Features the lowest pressure loss on the market
  • Features a high level of resistance to external factors (temperature change, waves, chemicals, stones, gravel etc.)
  • Features a pulsating flow, to prevent the accumulation of debris
  • Tried-and-tested – has been on the market for more than 20 years
  • Has few moving parts – practically maintenance-free

The WaStop is also available with an access chamber, allowing easy access from ground level. The product is then called WaStop Access. 

 

Wapro's solutions require minimal maintenance, have a low life-cycle cost and are simple to install. The delivery time for all products is short, and stock items are sent immediately.
