The plumbing storehouse is open. These rooms are the trade's side of the house — the same evidence rules as everywhere at Journeymen: one shop, one voice; outcome reports are the heaviest currency; documents are the other heavy lane; vendors are welcome as members and selling stays out of the discussions.
On the plumbing side of the site you'll find the state layer — plumbing code adoption and licensing for all 50 states and DC, each record showing how it was verified area by area and, where it's partial, exactly what would complete it. There is no plumbing docket yet: the trade's weighed knowledge hasn't been built, and nothing here pretends otherwise. These rooms are where it starts.
Safety rule, plainly: describe the rule or the practice. Step-by-step procedures for work that can hurt someone wait for the bench.
