Backwater valves

Showing the single result

Check valves are an important component in flood protection, especially for buildings with sewage systems. Their purpose is to prevent water from entering the sewer or wastewater system during a flood.

A check valve operates on the principle of a one-way valve. It allows normal wastewater drainage from the building but automatically closes when backflow occurs due to increased water pressure in the sewer system. This prevents water from flowing back into the building through the sewer and causing damage.

Check valves can be installed at various points in the wastewater system, such as on drainage pipes, in toilet and sink drains, or in basements or manholes. They are available in different sizes and designs to meet the specific requirements of your building.
