Failed motor - caused by reverse flow

[ThomasVaught]

I have come to believe that every motor "stage" (be it a single motor or a group of motors should have a "check valve" strategy to prevent motor damage. Between the large home built flapper valves, the flapper valves from the irrigation valves, or a ball valve type affair, there are ways to protect those motors today based on ideas generated by this fine forum.
