Finally got it in the tank and going. Started up pretty easy. It is virtually silent as well. I have also discovered that the increased pipe size (2") seems to suck off the surface better even though it doesn't have any more volume than a 1" pipe.
it is easier for the 2" pipe, since it can suck the water from a bigger surrounding surface area due to its larger diameter and therefore doesn't need as much "sucking"
in addition, you don't get the nasty "maelstrom effect" in the middle of the pipe, which for smaller diameters can trap air and prevent waterflow.
very good idea indeed!
