I based my opinion on an article titled Side Effects May Vary, damage from drywall, part 2 by David Shapiro in the October issue of Electrical Contractor Magazine writer@davidelishapiro.com
It is very simple, if his insurance company or AHJ requires it, then it is not a choice, many insurers will not renew until all plumbing and electrical is replaced. It really is not a call you have to make.
