If you smell gas nowLeave the building without using switches, flames, or phones indoors. From outside, call 911 if there is immediate danger and call your gas utility. Contact a private-side contractor only after the area is declared safe.
The short answer
The scope should match the work: new and altered piping may require a permitted test, while untouched piping may still need evaluation if it was disturbed. Photos and route documentation are valuable before drywall or cabinetry hides the work.
What matters in this situation
A pressure test answers a narrow but important question: does the isolated piping hold at the required test condition? It does not identify every defect by itself, and a failed test still needs systematic leak location.
Details that help define the next step
- New, moved, and removed appliances
- Piping sections opened or concealed
- Permit and inspection stage
- Contractor responsibility for final connection
These details help establish scope; they do not replace an emergency response, onsite inspection, utility decision, permit requirement, or manufacturer instruction.
How a careful service process is organized
- Start by documenting new, moved, and removed appliances and piping sections opened or concealed.
- Confirm permit and inspection stage and contractor responsibility for final connection before the scope is finalized.
- Have plans and appliance specifications and photos before concealment ready for the onsite team or authority.
- Use the findings to define the appropriate gas pressure testing scope, required testing, and any next authority or trade.
What to have ready when requesting service
- Plans and appliance specifications
- Photos before concealment
- Inspection contact
- Access to all altered branches
What not to do
Do not close walls around uninspected work when inspection is required. Keep relevant tags, notices, equipment information, and safely obtained photos available for the people handling this specific situation.
