First cruise with the Jabsco VFlo series 42755. Very much like the variable flow and low noise. The issue is intermittently it will just idle with no taps open. No leaks in the system. It will idle at about 3 amps, sometimes shut down on its own and other times it’s thermal overload will shut it down. I do not see a pressure adjustment. Have not tried Jabsco yet. Any ideas?
