I would like to know the freeze line in Bristol Tn and the recommended depth for water line also where I can find listings for different areas. I would also like to find specifications on freeze failure for schedule 40 pvc.

Local zoning codes will specify at what depth you need to berry a water line. As for the other part of the question, do a search for ASME and there should be some specs on burst pressures there.

I think no one would take into consideration about when the pipe would failed, they think it would failed when frozen
