Brandon Whitmore Posted September 4, 2015 Report Share Posted September 4, 2015 I'm doing a little research, and hoping some of you can help.... Section G2421 of the ORSC: Oregon Code requires flow controls (MP regulators) be listed as complying with ANSI Z21.80 spec's. Do y'all in other states have this same requirement? After doing some digging into which regulators have been tested to those specifications, I'm not finding many. I'm slowly compiling a list of regulators with this approval.
