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
 Neighbors point to shoddy materials. The plumbers and news reports
point to the utility. The utility of course points everywhere else,
