Thanks to all for the compliments!
Marc D - Yep, I used unions so I can take it all apart come fall when I close the pool. I think the total cost was around $70 or so. The unions are around $7 each, and the valves are around $11 each. The pipe and associated 90 elbows and tee's are cheap. All told, I spent about 8 hours doing it, off and on. I had to move the blocks that the pump/filter sits on back a bit, and that entailed relocating the ground rod my electrician installed, which took some time. Nothing like working a four or five foot grounding rod out of the ground with a pair of vice grips and a hammer. My arms and chest are still sore.
FPM - Shoot yeah, I can be persuaded to be hired out! For the right price, I'll do just about anything.

The lower return is exactly that - a return. My pool came with both the upper and lower return. I use a suction side cleaner, either a manual one (me) or an Aquabug.
I also replaced my skimmer with a Hayward model. I believe my old skimmer was a Waterway, and I was having a hard time finding skimmer baskets for it around here. Not so for Hayward. I also bought an aquadoor, and figured if I was going to have to take the faceplate off anyway, might as well replace the skimmer now.
