Installation
Quick installation for immediate protection
The WaBack non-return chamber is designed to provide fast and effective protection against flooding and backflow. Delivered as a complete unit that combines an inspection chamber with an automatic non-return valve, it significantly simplifies the installation process.
The installation is highly flexible and can be adapted to existing pipe systems. WaBack can be installed in various types of pipelines and is compatible with sizes from DN110 to DN315. To ensure proper function, the chamber should be installed at the same slope as the pipe since it does not have a built-in gradient. It’s important that the flow direction in the chamber matches the flow direction of the pipes.
To make installation even easier, a range of accessories is available, including riser pipes, reduction cones, and chamber lids in various sizes. When installing in areas exposed to groundwater pressure, the product should be securely anchored to prevent it from floating. This is especially important for the WaBack Access Large, where the maximum installation depth is 2.5 meters from the pipe invert to ground level.
WaBack requires minimal maintenance and is made from corrosion-free materials for long-lasting performance. For added safety, it can be supplemented with a water level alarm that provides both visual and audible alerts if water levels rise.
With WaBack, you get a reliable, sustainable solution to protect your property against flooding, with an installation process that is both simple and cost-effective.
