FDA approved/listed epoxy resin for potable water is the ONLY method to
be used. Leachables from most resins are a BIG problem in potable
water systems. Even when I use food grade epoxy, I recirculate/strip
all the leached monomers through a carbon bed stripper system for a few
months, etc.

Can you give me the name/manf. of an FDA approved epoxy that I can use?
