Side track: I like the flow check Idea, Very useful for say a water heater,very practical idea with battery back up no less for those seasonal applications.Adjustable time, for main or small demands.Even a pressure switch for the water heater.
OK, Now that we got that outa the way.How old are the cables?
I would do a good inspection of the cables, at a min, I would change all jumpers from box to box affected,all affected devices.The good news is usually once the water finds it's path it stays with it.
Always think 'liability'.
