Suction Strainers with Backflow-Prevention Valve

Also known as foot valves, these strainers stop particles from entering your line while preventing backward flow. They are commonly used with reservoirs and tanks.

With Bronze Female Threaded Pipe Fitting Connections

Strainers with bronze or PVC connection have better corrosion resistance than strainers with an iron connection; bronze strainers are often used in water-delivery applications.
