I am currently planning on using a couple of pieces to get me down to 1.5" (6x6x4 tee and then a 4x4x2 tee followed by a 4 to 2 reducer and then a 2 to 1 1/2 reducer). Trying to get to 1 1/2" in the vertical part of the vent so the shop vac can be used to vacuum out the air to start the siphon. The horizontal part will be 2" and have a value in it to asist in the manual siphon. Just was trying to see if I can get by will less parts and a more direct route? See drawing here
