These folks say that the best way to deal with the system is to turn it off manually during times of heavy rain, then turn it back on. I was told even to consider turning the system off altogether—or at least considerably reduced—during the winter when plantings are dormant. Thanks for the videos; sometimes I feel as though one needs a PhD to understand that box in the garage....
