Product overview
WaBack Non-return chamber
Self-activating, reliable and robust – WaBack® is a dependable and effective solution for protecting properties against backflow and flooding in wastewater and stormwater systems. With its unique design, WaBack® offers immediate and automatic protection, especially suited to handle heavily contaminated water. The fully open flow area ensures no clogging occurs, minimising the risk of blockages and the need for maintenance.
Why WaBack is a sustainable choice for future flood protection
- Automatic and energy-efficient protection: WaBack is activated by the water flow without the need for electricity, reducing energy consumption and operating costs while supporting sustainable use.
- Protection of water quality and ecosystems: It prevents contaminated wastewater from reaching drinking water reservoirs and natural watercourses, protecting the environment and human health.
- Optimal flow capacity and reduced maintenance: The open design ensures free flow under normal conditions and minimises blockages, reducing the need for chemical cleaners and resource-intensive maintenance.
- Easy installation and long lifespan: Made from durable, corrosion-resistant materials for easy inspection and long-lasting performance, lowering the need for frequent replacements and resource use.
- Reduced environmental impact from repairs: By preventing flood damage to buildings, WaBack lowers resource use and the climate impact from clean-up and repair works.
Installation
The WaBack Non-return chamber is designed to provide quick and effective protection against flooding and backflow. It is delivered as a complete unit that combines an inspection chamber and automatic non-return valve, which significantly simplifies the installation process.
The installation is 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 with the same gradient as the pipe since the product does not have an integrated slope. It is important that the flow direction in the chamber follows the flow direction of the pipes.
To facilitate installation, various accessories are available such as riser pipes, reduction cones and chamber lids in different sizes. When installing in areas at risk of groundwater pressure, the product should be properly anchored to prevent it from floating. This is especially important for the WaBack Access Large, where the maximum installation depth is 2.5 metres from pipe invert to ground level.
WaBack requires minimal maintenance and is made of corrosion-free materials for long life. For extra safety, the product can be supplemented with a water level alarm, providing both light and sound signals in the event of rising water levels.
With WaBack, you get a reliable and sustainable solution to protect your property against flooding, with an installation process that is both simple and cost-effective.
