What does this plumbing pre-cover checklist cover?

14 items across 3 sections, covering slab and underground release, wall and ceiling release, release sign-off. Each item spells out what the person walking the job is actually looking for, not just a box to tick.

Who should run this inspection?

The GC's superintendent with the plumbing foreman, releasing slab and wall areas for pour or cover.

When in the schedule should this walk happen?

After the rough-in and pressure test pass, the day before slab pour or the day drywall is scheduled on each area.

Why do these items ask for a photo?

11 of the 14 items call for photo evidence, 15 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.

What most often fails a plumbing pre-cover inspection?

Slab areas poured over piping with only a passing test on record, no photo of the gauge at pour time. Sleeve locations for future fixtures not matched against the fixture plan before the slab is closed. Test plugs and caps left loose, discovered leaking after the concrete is down.

Can I use this checklist in RTI?

Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.

Plumbing pre-cover inspection checklist

A plumbing pre-cover inspection is the hold point before concealed work disappears behind the next layer. This checklist is built for that walk: verify, photograph, then release the cover, not the other way around. Work is commonly verified against IPC / UPC family. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

Slab and underground release

Test pressure still holding at time of pour
Gauge photographed on the day of pour showing the same reading as the original test.
Sleeves and stub-outs match the fixture plan
Stub locations checked against fixture rough-in dimensions before concrete covers them.
Trench backfilled with approved material and compacted
No sharp debris against the pipe, compaction lifts consistent with the geotechnical requirement.
Drain stubs capped and blockouts formed against the pour
Every drain stub capped so concrete and slurry can't get in, with blockouts at tubs, showers and floor drains formed to the size the fixture needs.
Stubs and risers tied off against the pour
Risers and stub-ups staked or tied to rebar so placement and vibration can't knock them out of position or plumb.
Under-slab runs dimensioned before concrete
Runs and fittings located by tape from gridlines or walls and marked on the as-built set before the pour covers them.

Wall and ceiling release

In-wall piping test still holding before drywall
Gauge reading confirmed the day drywall is scheduled, not left over from the rough-in date.
Firestopping complete at rated wall and floor penetrations
Listed firestop system installed and cured at every pipe penetration through a rated assembly.
No conflicts with other trades' backing or blocking
Backing added for cabinets or fixtures does not crush or shift any pipe or valve body.
Supply lines in exterior walls inside the insulation line
Where water piping runs in exterior walls or unheated spaces, it is kept on the warm side of the insulation, or insulated as the drawings show.
No photo
Every concealed valve and cleanout has a planned access
Each valve, cleanout or trap primer going behind a finished wall has a framed access panel opening lined up with it, or is reached through its trim as drawn.
In-wall valve bodies and boxes set to the finished wall depth
Shower valve bodies, fixture carriers and washer or ice-maker boxes set within the trim maker's range for the finished wall build-up, tile and backer included.

Release sign-off

AHJ rough-in approval recorded for the area
The inspector's approval of the underground or in-wall rough-in is on file for this area; no approval, no release.
No photo
Pour crew briefed on where stubs and risers stand
Finishers and the pump operator walked through stub and riser locations so hoses, screeds and buggies stay clear of them.
No photo

What usually sends this back

The failures are almost always the evidence, not the work

Slab areas poured over piping with only a passing test on record, no photo of the gauge at pour time.
Sleeve locations for future fixtures not matched against the fixture plan before the slab is closed.
Test plugs and caps left loose, discovered leaking after the concrete is down.

Verified against

IPC / UPC plumbing codes
