Fixture, valve, drain, and vent locations match the approved finished layout

Critical item

Rough-ins should align with selected products and finished surfaces without field improvisation.

Drain and vent routing, slope, fittings, and cleanouts are complete

Critical item

Drainage and vent piping should follow the approved design and adopted plumbing requirements.

Pipes are supported and protected from fasteners, movement, freezing, and abrasion

Critical item

Supports, sleeves, nail plates, isolation, and insulation should suit the piping and framing conditions.

Shutoffs, mixing components, carriers, and concealed connections are secured

Critical item

Valves and supports should remain accessible where required and resist operation loads without stressing piping.

Required pressure, leak, drainage, and permit inspections are passed before cover

Critical item

The applicable test and official inspection should be complete before concealment.

Pre-cover photos and approved corrections document the entire rough-in

The owner should retain a location record for future drilling, service, and warranty claims.

Use after bathroom supply, drain, waste, vent, and fixture rough-ins are installed but before insulation, backer, drywall, or flooring conceals them. Licensed-trade and permit requirements vary. Inspect from the room, accessible framing, and dated stage photographs. Do not energize exposed electrical work, pressure-test systems without authorization, or walk on uncured waterproofing, mortar, or heating assemblies.
