100' of 2" PVC has the equivalent head loss of a 1' vertical rise. And even that is at a 20gpm flow rate. Less flow and it's much smaller. That's it. By comparison, a 2" 90 deg elbow is the equivalent of a .1' vertical rise. Put it this way, 5 elbows is the same as 50' of straight pipe. Straight is good, lol...
