Thanks to "something" [1] that caused pinholes in my home's copper pipes I broke down and had the entire hou$e replumbed with cpvc.
Some of the pipes are outdoors though and the CPVC manufacturer recommends shielding them from UV to avoid brittleness. A "water based paint" of some unspecified type is an allowable covering.
Could someone suggest a suitable brand I might find in the US, or failing a brand name, a type I can look for that I guess won't be so reactive as to dissolve the cpvc? Thanks in advance
