I think most water purveyors use the USC guidelines.
I remember when the clean water act and IDEM got involved. We just finished a new install at a restaurant and had a quick coupler before the PVB, they made us cut it out. Had to use a Leary bicycle pump to clear the water before the backflows. I have no comment on later years.
