Another thought... Conduit is _going_ to be too thin. I'd use black steel
pipe that's used for gas lines (or if you want a rust free solution, spend a
bit more and go with galvanized for water). It's going to cost a bit more,
but then you can have the advantage of threaded fittings and unbendable
lines.

Really, it'll cost less, because you'll be wasting your money on the conduit
and have to use something else anyway ;)
