Plumbing photos that do not lie about slope

You cannot photograph “1/4 per foot” directly—you photograph context: long lens down a joist bay, laser in frame if that is your thing, cleanouts at grade before they get mulched. Pan connections and tub traps love to become theology; wide shots first.

Water tests and witnesses

Tub fill, flood test ball, shower pan flood—whatever your AHJ wants, shoot the setup and the result. Captions with time (“started 2:10p, checked 4p”) save you from astrology later.

ProPress / PEX / copper—show the work

Ring visibility, support spacing, isolation valves labeled. If it is pretty, photograph it before insulation makes it a rumor.
