I am dealing with a 50 yr old apartment bldg on a pier & beam foundation with 2" copper water supply lines. We have had quite a few leaks over the last 6 months, and I'm wondering if it is possible to replace it with something besides very expensive copper. Not sure how we'd get to the pipes that go up into the units, but it sure would be nice to at least have peace of mind and get that 50 yr old stuff out of there.
 
PEX is a possibility. As far as getting it up to all the units, they sell manifolds that you can use to branch to different locations.
 
remove the copper pipe, sell it for scrap. to offset the price of the pex
if you do scrap it out.
copper is bought by scrap yards graded As #1 or #2

copper that does not have solider fittings on it is #1

solider /fittings is #2

they will try and tell you because it is not shiney its #2. they are trying to get over on you

when you confront they with knowledge, they back down and give you the #1 price

cut all the fittings off and have 2 piles #1 and #2
 
plastic is plastic and if you are going under a slab it has to be copper and has to be brazed
 
By code in Kentucky warsbo or pex is perfectly legal in slab as long as it is sleeved and no fittings
