Abstract
A backwater flow detection device for detecting backwater flow between a building and a sewer conduit using air pressure detection in air pockets in the sewer conduit. The backwater flood detection device detects backwater flow events including backflow events from a sewer line as well as wastewater blockage events that can result in wastewater backflow into a building. The water detection sensor allows the homeowner or building manager to be warned when there is an issue with backwater flow in or near the building, and also with the backwater valve.
