Question for Little Giant pump users
The 4mdq max is 850usgph@1'tdh and flow decreases from there as head increases. Obvious signs of starvation are excessive pump noise due to cavitation (gravel/marbles going through pump) & *not*...

Hey Darren.
Dont know what the manufacturer told you about measuring across a pole - IME it has always been on a power lead at the motor.
