A plumbing rough-in (or top-out) inspection checks supply, drain, waste and vent piping before walls are covered, along with the pressure tests. This checklist covers the piping, DWV slope, vents, cleanouts and trap arms, the water and DWV test readings and how long they held, and stub-outs and valve labels.

This is a field checklist, not the code. Your inspector enforces the code and local amendments your jurisdiction has adopted.
The stage when supply and DWV piping is roughed in through the walls and up through the roof, before insulation and drywall. Many inspectors call the inspection rough-in or top-out.
It depends on your local code and the piping: commonly a water or air test on the supply lines and a water or air test on the DWV. Record the pressure and how long it held.
1/4 inch per foot is typical for smaller drains and is this checklist's reference, but the required slope depends on pipe size and your adopted code.
