Tossing an idea around that will run two HE Pumps in series. If one fails or is turned off will it still free flow or will it block flow? I know cooling is often discussed but has anybody tried this to get the flow up? I have room for a second HE and think the extra flow and cooling could help. It sounds logical but IDK. Any thoughts for or against appreciated.

 

its not needed the pumps are not that unreliable

 

Do you think the extra flow would help? It would be simple to do.
