During construction the rough-in (rough) plumbing inspection is generally performed at what point?
a.After the DWV and water piping are installed but before they are covered or concealed
b.After all fixtures are set and the building is occupied
c.Before any trenches are dug
d.Only after the final walk-through with the owner
Giải thích
The rough-in inspection is done once the drain, waste, vent, and water lines are in place and tested but still exposed, so the inspector can view the piping before walls and slabs conceal it. Scheduling it after cover-up would force demolition to inspect. Plan the job so this hold point is met before insulation, drywall, or pour.
