I used the quiet one 1200 this way last summer and it was pumping faster than 1 tank could drain (it all depends on how high you go). I agree with rickztahone on picking up those 55. If you have the room, you'll find use for them later down the road.As usual, excellent thinking Van! I just may do that. I could get away with that 317gph pump and a plastic 55g drum or two in case one gets too ful. I guess I will need those after all.
