My gauge is ready high 20-25 psi even after I back wash. The thing that concerns me is that the pressure gauge frantically vibrates. I’m think turbulence perhaps but idk. Has anyone dealt with this issue?
Same hp but but not a vs pump. The vs pump is only at the rated hp when it's at the top rpm and anything below that is a fraction of the rated hp. A single speed pump is always at the rated hp so this may be the issue going on. You're running at a much higher rpm then the vs pump.
