Support 248 CMR 10.00, the Massachusetts Plumbing Code — one of the few remaining state authored plumbing codes in the country.
Apparently, there have been talks about changing MA plumbing code to the National plumbing code. Those who oppose to change (licensed plumbers) say the change will allow homeowners to pull their own plumbing permits and do their own work.
"There may be future efforts to displace 248 CMR 10.00, the Massachusetts Plumbing Code in favor of a National Plumbing Code, promoted by home builders and building officials but not supported by the Massachusetts plumbing industry."
I don't know what else this means.
