Marc, yes, I am building the entire house myself [:-wiltel] I did pay someone to do the slab and the plumbing in the slab, other than that it's been all me...and yes it is an exterior wall, I plan on building a box around the manifold like this guy did; with a nice, cabinet style door for it. I haven't had any dealings with the inspectors in West Monroe yet but I haven't heard any horror stories yet so...[:-thumbu] Mike, I have been looking all over online about those fittings, I usually do that before I come to you guys. Maybe I can call Apollo and ask them? Mike, Nolan (thanks for the Apollo PDF), Concerning the radius of the hoses, I plan on drilling the studs and going through them with the hoses so the radius will be very gradual. Like this guy did; I'll post pictures as I go along to make sure I'm not making any mistakes along the way.
