A plumbing inspection checklist does two things: it ensures nothing gets missed on the job, and it creates a documented record that protects you if anything is disputed later.
This checklist covers every stage from rough-in through final walkthrough.
Rough-in inspection checklist
Supply
- All supply lines run per approved drawings
- Pipe sizing correct throughout
- All shut-offs installed and accessible
- Isolation valves at every fixture

- All penetrations through fire-rated assemblies sealed
DWV
- All drain lines run at correct grade (min 1/4" per foot)
- All vent connections complete
- Clean-outs installed at required intervals and locations
- All DWV joints properly solvent-welded or leaded
- Smoke test or water test completed
Rough-in dimensions
- Toilet rough-in confirmed (typically 12" from wall)
- Shower pan drain centred per plan
- Sink rough-in heights correct
- Tub/shower valve rough-in at specified height
Pre-cover documentation
Before any framing, drywall, or flooring covers the rough-in:
- GPS-tagged photo of every valve location

Making this checklist digital
Paper checklists get wet, lost, and disputed. A digital checklist where each item requires a photo before it can be checked off creates an automatic documentation trail — without extra steps.
Manifold's required-photo checklists let you build this workflow once and use it on every job. Each item requires a photo. Every completion is timestamped. PDF exports automatically. See our plumbing contractor app guide.
