Whether you agree with the regulations or not is a moot point. The regs are here to stay and California is already fining those that don't comply so I would imagine that if your CSV has any brass or bronze in it, it is illegal to install there. Other states are following suit as expected.
Actually the Federal Government is adapting the same rules for all 58 states in 2014.
CSV’s now comply with the new regulations. Just letting everyone know we had to pass this cost on down to the consumers. My opinion is not a moot point. I have hopes of someday having a sensible government, which is why I speak out about such things.
