Well, I am looking at the pex more seriously now. I really like the manifolds where you can shut off individual runs, which means I can *add* individual runs as I get to them. CPVC would be cheaper, but the idea of the pex being more burst resistant..I like that. I'll check out the local plumbing supply guys, they treated me good before and put up with my noob questions.
I am trying to not hate plumbing...really trying. If I had ground clearance to get to the pipes I could fix them and insulate them and hang them from the joists and run some sort of heat under there..but that would require jacking the house up, trying to wiggle a backhoe under there to dig out for some room, or just jacking the house up a few more cinder blocks higher and new foundation, or removing all the kitchen and bathroom flooring, most of it, and all the stuff on top of the flooring, finding someplace to put that stuff... bah.... just bah...
My Gf is not amused right now and is giving me serious grief as well, #$%&&^$##$%%^ I got five buckets of water in the bathroom for flushing but she is still kvetching about it. Sucks, just when you need some moral support...like it is my fault it wasn't fixed in ten minutes...
Anyway, sorry for the derail, this is really the only place I got to go ask questions, where I know I can get some answers, and a lot of you guys have so much experience with hot water plumbing because you got OWBs etc. And I have to get this fixed before the next real cold snap hits or I'll lose the cold water as well.
