Product review (5 stars): Insurance Co's say since the rubber will breakdown you should replace these like every 5 years
Color coded hoses for the choosy home owner.  My brother and I installed these for my mom.  Replacing hoses from 1988 that were rubber was kinda big deal.  Insurance Co's say since the rubber will breakdown you should replace these like every 5 years.  Not hard to do and basically good for peace of mind replace these hoses from time to time.
