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
Vacancy adds unknowns: missing appliances, open branches, stolen piping, corrosion, and undocumented caps. The initial walkthrough should establish a safe test boundary before pressure is applied.
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
- Length and reason for vacancy
- Missing or disconnected equipment
- Visible damage or open piping
- Utility and municipal restoration requirements
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 length and reason for vacancy and missing or disconnected equipment.
- Confirm visible damage or open piping and utility and municipal restoration requirements before the scope is finalized.
- Have ownership or management authorization and all-unit access 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
- Ownership or management authorization
- All-unit access
- Prior inspection notices
- Plan for appliance reconnection
What not to do
Do not restore gas to unknown or uncapped branches. Keep relevant tags, notices, equipment information, and safely obtained photos available for the people handling this specific situation.
