Introduction to Backwater Valve (BWV)
Fernco’s range of In-line Backwater Valves (BWV’s) support the flood prevention methods used in the installation of new drainage systems.
A physical barrier between your home and the public sewer to defend against backflow flooding. BWV’s have a proven and robust design to be automatically operated, providing a free flow of sewer or surface water materials.
Maintenance free and easy to install; BWV’s can be connected to any pipe material using a shear-banded coupling or Icon coupling.
Available in a range of sizes to accommodate the most common smooth PVC pipe sizes: 110mm, 160mm and 200mm and single and double-flap options are available.
