Another idea N+1
I was wondering what the faileure mode is.
If the pump - run two in parrellel with check valves ?
If the jet maye two or better still a staged system one on at say 10 psi or what ever is 1/2 the max flow needed and the second at say 15 psi providing the other 1/2 of the flow . If one system fails you still have 50% of the flow worste case and tune accordingly on the conservative side.
I assume this has been done ?
There must be a problem other than it costs twice as much ?
Thanks Charlie
