What a plumbing inspector checks, and what happens if something fails

A plumbing inspection is the building department's check that permitted work matches the adopted code before it is closed in or put in service. A fail means a correction and a re-inspection, not a penalty.

//Quick answer

  • The inspector checks the work against the code the city has adopted, not against a preference.
  • A failed inspection is a correction list, then a re-inspection.
  • The most common flag in Done-Rite's experience: a missing carbon monoxide alarm.
  • Your city's building department owns the checklist; confirm specifics with them.

01Definition

What is an inspection for?

It verifies that the permitted work was done the way the adopted code requires, at the point where it can still be seen. For a water heater that is after the install; for a sewer line, before the trench closes; for a repipe, with the piping exposed and under pressure; for gas, during a pressure test. The inspector signs the permit when it passes, and that signature is the record.

What does the inspector generally look at, by job?

Water heater: gas or electrical connection, venting and clearances, seismic bracing, water connections, the relief valve and its drain. Sewer: material, slope, bedding, connections, and a test before backfill. Gas: a pressure test, pipe size for the total demand, materials, support and shutoffs. Repipe: material, support, protection through framing, routing, and a pressure test at rough-in. Each list is general; the authority having jurisdiction has the actual checklist.

02When it applies

What happens when an inspection fails?

The inspector lists the corrections. The contractor fixes them and schedules a re-inspection. It is not a fine or a citation; it is the process working. Done-Rite treats a correction as its own to fix, not yours to chase.

What is the most common surprise on an Orange County inspection?

In Done-Rite's field experience, the most common thing an Orange County inspector flags on a permitted plumbing job is a missing carbon monoxide alarm, so the crew checks for one before scheduling the inspection. That is field experience with local inspectors, not a statement of what the code requires: the California Residential Code (R315.2.2) exempts installation, alteration and repair of plumbing systems from the carbon monoxide alarm trigger.

03What goes wrong

What goes wrong when work is never inspected?

The mistakes an inspector would have caught stay in the wall, in the trench or at the appliance. Some show up as a leak years later; some show up as a failed home inspection at resale; the gas and venting ones can show up as a health problem. The point of the visit is that somebody who is not the installer looks.
