I believe you are confusing California or other States codes with National codes.
Prior to 1977, Pvc did leach toxins and I think it was recommended only for sewage and household drains. But after 1977, manufacturers changed the formula to increase the safety of pvc. Pvc can now be used for cold potable water. Potable water means it is drinkable whether its installed indoors or outdoors. The word potable is even stamped on white pvc pipe. Even with copper pipes, its recommended to run the water a bit before drinking.
The state of California must have the strictists codes of all because everytime I buy a product like paint etc etc , the warnings will say the state of California has determined that the product contains toxins . So one might ask; why just the state of California? Seems to me they been crying wolf too long. Now as for hot water use, I do not think its approved for that.
And that is probally why cpvc is the choice for both cold and hot water.
