About 13' of rise, 2'-3' of horizontal. Max head on the pump is 24'

Mark just remember that you can down grade a pump from the output but its not wise to down grade from the input so if your pump has a 2" going in stick with the 2" but that is my opinion> and that is what i have read too.

I agree, reducing the pipe size on the suction side can and usually does cause cavitation, which will destroy the impellar.

you'll loose some head reducing the outlet from 2" to 1.5", might get some idea of how much from RC's headloss calculator
probably not a whole lot of cost or effort difference though just sticking with 2"

No, probably not a lot of cost...just was trying to save a little space. Plus I didn't figure the pump was actually pushing the entire 2" pipe full of water all the way up the pipe, but maybe it does.
I don't plan on restricting the input. My sump has a 2" bulkhead hole cut to connect to the Reeflo.

keep the elbows to a minimum as well, huge head loss thru 90's
