Check valves are designed to allow flow in only one direction, which makes them particularly important and suitable for water treatment and distribution applications. Beyond that, they can be crucial to maintaining pump health by preventing water hammer.
Brian Allen is the engineering manager for Flomatic Valves, based in Glen Falls, New York. He explains what a check valve is, how they work and some common maintenance tips. He also reviews the similarities and differences between a check valve and a backflow preventer, and notes the importance of talking to an engineer to find the best valve for your needs.
