Inline Check Valve
The revolutionary patented and certified Wastop® inline check valve can be installed in minutes in a pipeline or chamber. It can be installed either horizontally or vertically and either at an inlet or outlet. WaStop® can be installed to prevent backflow in all cases. Flow in the normal direction causes a slight pressure buildup against the membrane which in turn causes the membrane to open just enough to allow the flow to pass unhindered. When backflow occurs the membrane fills with water or gas and acts as a stopper blocking all back flow in the pipe or drain. WaStop® check valve can be designed to withstand up to 12 meters back pressure.

Basement flooding
Installing a WaStop® inline check valve in the buildings` drainage system or in a basement can protect the property from flooding. Installation costs and time invested can be kept to a minimum by installing a WaStop® in an existing drainage system.
Odour control
The discharge of odours or aggressive gases from sewage systems can be a major problem in some areas. Discharge can be stopped, or directed to a less sensitive area by installing a WaStop®.
Waste water, surface water and tidal areas
WaStop® protects wastewater and stormwater pipe systems from high water levels in rivers, lakes and tidal areas. By installing WaStop® insects and small animals are also stopped from entering storm and waste water systems.
Emergency overflow
Flooding may occur between waste and stormwater drains caused by water forcing its way back into the drainage system. To prevent this a WaStop® can be installed in the emergency overflow.
Wetlands
Prevent salt water or other unwanted water from forcing back through an outlet leading to flooding of wetlands or other flood sensitive farmland.
