check valve in bilge pump line

[jetblue319]

well, you got me sold . no check valves, i did purchase smooth inside diameter clear hose. the article (boating mag.mar.2017) did mention to place the check valve in a easy access area to check for clogged and the reason for check valve was to prevent cycling of the pump in the event during launching the boat, the discharge port was placed under water, or if the boat was to list. thanks again jet
