I checked the sinks. apparently I didn't leave them on enough of a drip since the hot water lines froze. the original plumbing was not run the way I would ave run it was not insulated properly. the builder came out the first winter we were here and 'fixed' it. Apparently not....

the pipes run a long way across the attic. The factory put some conduit in for running services up to the attic, but they did it in the wrong spot. they should have done it in the middle of the house where the bathroom was going to be. I think that what is frozen is nearer to the fixtures than anywhere else. It would be possible for me to reroute up an inside wall, but would be some major surgery.

I've never seen water pipes in an attic.

I came to a stop sign and a skanky tweaker chick in a tube top climbed out of the brush and propositioned me. She looked like she didn't have any teeth so I counted that as a plus.

So, you think the pipes are freezing in the attic, not the wall? That might be good. Apply insulation over the pipes and remove it from under the pipes. If things run parallel and perpendicular to joists, it's pretty easy. I'd use rigid foil backed foam and duct tape to make some chases piling up loose or batt insulation where you meet the existing. Pictures would help.
Here, slab homes traditionally have fresh water under the slab. Soft copper that can be bent up at fixture locations (no connections under the slab).
Now, with the use of PEX, its all attic run. But, we don't get that cold.

the pipes are freezing in the attic. they run up an interior wall to the attic, then go about 25' across the attic on top of the joists. the wall behind the tub in the bathroom is the attic. we thought we had this licked since they didn't freeze last year. I'm going to deal with it later this year after the weather gets nicer. I can get back there, it's just a PITA. I will probably go back, take lots of pics then come back out and decide on a plan with the pics. I believe they are freezing closer to the bathroom.

Good. Like I said, remove insulation between the pipes and the warm house. Place insulation between pipes and the cold attic. Should be intellectually trivial. No clue how much of a PITA the work will be since it isn't my house.
