For years, residents of the Village of Lindenhurst in Long Island, N.Y., have suffered with serious recurring flooding issues. During storms, flooding could reach several feet in such a short time that residents found themselves suddenly trapped, unable to drive safely, with school buses unable to pick up children. Even more concerning, emergency vehicles were unable to reach people in need of help.

A group of residents explored legal action as flooding had become disruptive and dangerous over the past few years. The Village of Lindenhurst needed a cost-effective solution before the multitude of problems caused by recurring storm flooding became worse.

A Simple, Cost-Effective Solution

After a thorough review of options with engineering consultants, local officials selected CheckMate® UltraFlex® In-Line Check Valves, manufactured by Red Valve Company, to help prevent the backflow problems causing flooding. The patented CheckMate UltraFlex valves restrict water from flowing back into the streets, effectively eliminating backflow while also helping to protect area wetlands and beaches.

Fast, Easy Installation

Installation of the CheckMate UltraFlex In-Line Check Valves was easy, since no adjustments to the structure or pipe were necessary. The valves run on differential pressure, so no outside energy source is needed.

Long Term Performance

The CheckMate UltraFlex In-Line Check Valve’s exceptional durability and performance were other factors in the selection for this installation. Each valve is made with multiple layers of natural and synthetic elastomers, with no molded parts, rivets or fasteners that can come loose or break. This makes the CheckMate Valve essentially a lifelong product that is maintenance free and user friendly, designed for long terms performance in many applications.

Peace of Mind for Lindenhurst, NY
