The WaBack non-return chamber is a tried-and-tested product that provides immediate and automatic protection against backflow. The product is usually used as protection against basement flooding, and is fitted to service pipes and pipe networks. Used against overload and flooding in drains and as protection against backflow of surface water and waste water. The product is used to advantage in extremely polluted water, and can thus be used in both sewer and stormwater systems. The flow area is completely open, to ensure blockages are prevented.
