Mike, will that valve allow you to have all the ports wide open simultaneously? I don't have any Jandy's..I know they're good quality...but I was thinking a 3-way was an "either-or" valve but not both wide open.

Anyway, I think you're on the right track. An extra 90 turn or so won't add much head and you're really gonna' cut it (head) back if you can get two suction lines going. Let us know how you end up.
