Backwater Valves

When the flood waters come, water will seek every route to enter the building.  One route that is often overlooked when building a defense against flooding is the building’s drainage system.  Flood mitigation backwater valves are devices that prevent the flood waters from entering the building via that route.  Once in place, the FM Approved flood mitigation backwater valve will hold back the water and keep the building from flooding from the inside out.
