Plumbing Rough-In Inspection

It covers the items that should be verified before walls are closed: project details, drain-waste-vent routing, trap and cleanout placement, pipe support and protection, pressure or leak testing, and final readiness. The template is built to document observable conditions, not just a pass/fail result. It is meant to catch deficiencies that would be expensive to reopen later. If a local code or AHJ requires additional checks, you can add them to the same form.

Use it after rough-in piping is installed and before insulation, drywall, or other wall closure begins. That timing lets the inspector see slope, vent routing, supports, penetrations, and test setup while everything is still accessible. It is also useful after rework if a prior inspection found non-conformances. Do not wait until finish stages, because hidden piping issues are much harder to correct then.

A qualified inspector, superintendent, project manager, plumber, or site quality lead can run it, depending on your workflow and local requirements. On regulated jobs, the person performing the check should understand the approved drawings, permit conditions, and applicable plumbing code. If an AHJ inspection is required, this template can be used internally first and then shared as supporting documentation. The key is that the reviewer can identify defects in routing, support, testing, and access.

No. It is an internal verification tool that helps you prepare for the AHJ or other required approval. The template records what was checked, what was found, and whether the work is ready for wall closure. Final acceptance still depends on the authority having jurisdiction and the applicable code or permit conditions. Using this form usually reduces rework by surfacing issues before the official inspection.

Common misses include improper pipe slope, vent lines that are not connected as designed, missing or inaccessible cleanouts, inadequate hanger spacing, and unsealed penetrations where required. Inspectors also find traps installed at the wrong fixture or configured incorrectly, and pressure tests started with the wrong gauge or setup. Another frequent issue is documenting a test without recording the pressure and duration. This template makes those items explicit so they are harder to overlook.

Yes. You can add trade-specific checks for commercial kitchens, multifamily units, healthcare spaces, or tenant improvements. Many teams also add fields for pipe material, test medium, inspector sign-off, and photo attachments. If your project uses a stricter spec than the base plumbing code, add those acceptance criteria directly into the checklist. The structure is flexible enough to support both simple and highly detailed rough-in reviews.

They should be done for each area or system segment before closure, not as a one-time end-of-project review. On larger jobs, that often means repeated inspections by floor, zone, or fixture group. Re-inspection should happen after any corrective work that affects routing, support, or testing. The goal is to verify each concealed section before it disappears behind finishes.

An ad-hoc walk-through is easy to miss because it depends on memory and verbal notes. This template creates a repeatable record of the exact items that matter for rough-in acceptance: plans on site, piping layout, support, test results, and readiness for closure. It also helps teams assign corrective actions instead of leaving issues informal. That makes follow-up clearer for both the contractor and the inspector.
