Synopsis

This video demonstrates the operation of a backwater valve, specifically the "Topcheck" model. The valve features a gate that is located out of the sewage flow, ensuring that sewage doesn't come into contact with the gate during normal operation. The video highlights the valve's closing mechanism, which activates when the city sewer backs up, preventing sewage from entering the home.
