Thought maybe someone here had some expertise or experience with this.

My mom is buying a house built in 1965. Had structural/mechanical/plumbing/termite/electrical/etc. inspection and everything checked out ok.

The inspection uncovered that a pipe had burst in the slab at some point and the owners had to re-run plumbing through the attic and the walls for the entire house. The inspector (who was working for my mom- not the seller) said this is no big deal and everything was OK. He said the pipes they use for this are made for expansion/contraction so they don't have a high risk of freezing and bursting in the attic.

My mom wonders if this is an issue to be concerned about or not.

Anyone have any comments or experience with this?
