Video 1 ICLR basement flood maintenance series Backwater valve maintenance

A mainline normally open backwater valve is one of the best defences against basement flooding. But like any other part of the home, backwater valves require periodic inspection and maintenance to ensure proper performance over time. An improperly maintained valve may fail during a flood event. Mainline backwater valves come with a see-through top to allow easy inspection of the chamber to ensure the gate is working properly and that the valve is not clogged with debris. This video is meant to illustrate and provide general guidance on backwater valve maintenance. For complete and proper maintenance procedures, please follow all of the manufacturer's maintenance instructions.
