Just because somebody on a board said something, doesn't mean its true. Do your own research on non hobby related websites for real info. Search manufacturers website, NSF testing websites, industry websites, etc. I don't think you will find one that says CPVC is chlorinated to prevent biofilm - this is just somebody's conjecture, and a source of bad information that keeps coming up and gets regurgitated as gospel. The "chlorine" is added to create a plastic with dramatically different properties than PVC. BTW, the biggest source of leaching in PVC/CPVC systems is from the glue....

funny that came off the industry website of the maker of CPVC, i'll see if I can still find it and check it out though. this has also been told to me by several water places where I buy equipment.
