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.

I did a little more research and, while I found almost nothing about suction lines that are not drains or skimmers, apparently these types of lines are also used as dedicated vacuum lines. The thing is, that you are supposed to have special ports that close when a vacuum is not in use. I assume that is so you done suck up your nephew (or at least give him a big raspberry). I did not find any special covers to add safety. Withoutthat level of safety, I feel I cannot use that line as a suction. We run a day-care out of the house and thats too much liability unless a suitable cover exists.
