Backwater valves generally are used in sewer and drain systems to prevent the flow of flood water through these systems and into the building or structure desiring flood risk reduction. These devices are permanently installed and do not function until flood water reaches sufficient depths that will allow the water to flow into the building via the sewer or drain system. These devices are part of a flood proofing system.
