Overview
The City of Markham's information sheet on the plumbing rough-in inspection, distinct from its plumbing final sheet for the same trade at completion and from its plumbing drains and sewers sheet. It notes that this inspection is conducted with the framing inspection, and explains that drainage, waste, venting and water distribution systems are inspected to confirm they operate properly. A provincially qualified building inspector reviews materials and equipment, testing, piping, traps, cleanouts, slope and length of drainage pipe, stack vents and vent pipes, matched by a reverse-side deficiency checklist.
