Have a project house I've been working on, nearly done but market tanked so it sits. Anyway last winter the electronic ignition on the furnace did not kick in and the house froze in -10 weather. When I stopped by to check on things it was frozen solid, most likely in the teens temp wise inside. Since market has been so bad and I was busy on other things I let it sit.

At this point I'm tearing into walls and ceilings repairing what ever damage I can find, tracked down 3 or 4 blown off elbows and a number of split pipes. Question is how dependable is the rest of the hidden piping? If I pressurize it to 100psi with air and find no leaks will the rest hold? Hate to sell it and get a call back if something leaks in the future. What are the odds the sink and shower valves survived? The master bath has a two person shower with dual shower heads and 4 body sprays, all Delta. I would hate to have to replace those valves.

It would not be impossible to replumb with pex, though the entire 2 story house is finished basement and all, but there are chases to pull wiring and if needed plumbing.

Any thoughts?

Thanks for the input. Replumbing is something I considered, pex would not be too costly, just time consuming - plus I'd still have to open up the walls to pull it. Tracked down 5 or 6 blowouts and an equal number of blown off elbows. Got to replace the last 2 known blow outs the I'll know for sure. I know there are no definitiave answers as to the valves, but I can hope can't I?
