i all i recently changed from a trolley to a van mount and i have some problems with the digiflow controller .when start using it i calibrated automatically to cal 28.it work ok with the 18 ft pole but when i have some higher work i'm using the 30 ft pole and then it seems that like it's not enough power to push the water ,it looks like it's struggling .the water comes ok for a few seconds the looks like the pressure drops for a few seconds and then the flow comes to normal.anyone knows what's wrong.
thank you
