i just got my unit plugged up ...how much water should be coming out?...i drained all the air out of the lines and it is just trickling out...now it says to let the tank fill for 3 hours....do i have to sit here and wait 3 hours to turn it off???< also, it i supposed to make 100 or 110gpd...i don't see how it will ever make that much coming out at this rate...is that normal??? do i need a booster pump???
