Gas Line Pressure Testing

Gas Odour and Carbon Monoxide Come First

If you smell natural gas or hear hissing, stop and leave the building or area. Do not use a cellphone, operate switches, smoke, light matches or create another ignition source inside. From outside, call FortisBC at 1-800-663-9911 or call 911. Do not return until the utility or emergency responders say it is safe.

A carbon monoxide alarm or suspected exposure is a separate combustion and venting emergency, not proof of a gas piping leak. Get everyone outside, call 911 or FortisBC from outside, seek medical attention for symptoms and do not re-enter or troubleshoot equipment until emergency responders say it is safe.

Pressure testing is contractor follow-up after the immediate scene is safe and the system status is understood. An unresolved, non-active concern may first require Gas Leak Detection.

What a Pressure Test Proves, and What It Does Not

A passing result means the defined section met the applicable test conditions during the test. The scope matters. A result for one new branch does not apply to every gas line in the property, and a piping test does not commission connected appliances.

A failed result means the tested scope did not hold under the test conditions and needs investigation. It does not decide, by itself, that the whole system requires replacement. The next step depends on the scope, accessible evidence and what can be isolated or assessed safely.

Tightness and capacity are separate questions. Piping can hold a tightness test and still require a separate capacity assessment for selected equipment. Appliance operation, combustion, venting and commissioning are also separate from the piping test.

A test record should be read within its stated scope and limitations. An insurer, buyer, lender, inspector, utility, strata corporation or other third party decides whether that record satisfies its own requirement.

How the Test Scope Is Set

The test plan starts with the question the result needs to answer. The defined scope may be a new branch, repaired section, altered piping or a broader system, depending on the work and the available isolation points.

The applicable requirements determine the test medium, pressure, duration, equipment, isolation and documentation for that scope. There is no single published pressure, duration or gauge rule that fits every property and purpose. Components that must remain outside the test conditions are handled according to the actual system and requirements.

Restoration is not automatic after every test. The next step may depend on the result, repairs, appliance work, operating checks, a utility process, an inspection or another authority requirement. Appliance connection and commissioning belong to Gas Appliance Connection Service when they are part of the approved scope.

What Affects the Cost of Gas Line Pressure Testing

The price depends on the defined scope and the work needed to carry it out safely. Important factors include:

• Whether the test covers one branch, a repaired section, an alteration or a broader piping system.
• Access to the piping, shutoffs, test points, crawlspaces, suites, mechanical rooms and finished areas.
• The number and type of branches, appliances and components affected by the planned interruption and isolation.
• Whether gas is already on, off or locked, and whether a utility, permit, inspection or local authority process applies.
• Whether the defined scope passes or further investigation and additional testing are required.
• Whether confirmed repairs, new piping, appliance connection, commissioning or other work is authorized after the result.
• What restoration, operating checks or records are included in the quoted scope.

A useful quote identifies the purpose, tested scope, expected interruption, included work and the process for handling a failed result. It should not imply that every possible repair, restoration step or third-party requirement is included automatically.

What to Clarify Before Testing

Before approving the work, make sure the proposed scope answers these questions:

1. What piping is included? Identify the branch, repaired section, alteration or broader system that the result will cover.
2. Why is the test being performed? The purpose may be project completion, repair follow-up, investigation, restoration, an authority request or private due diligence.
3. What will be unavailable? Confirm the expected gas interruption, access needs and which appliances or areas may be affected.
4. What does a pass or failure mean? The answer must stay tied to the tested scope and conditions rather than becoming a conclusion about the entire property.
5. What happens after the result? Ask whether further investigation, repair, appliance work, a utility step, an inspection or another authorization may be required.
6. What record is included? Confirm what test information will be recorded and who needs to receive it. The receiving party still decides whether it satisfies its requirement.
7. What is outside the quote? Clarify whether restoration, repairs, new piping, appliance commissioning, permits, inspections or third-party fees are separate.

Property and Responsibility Questions

The service address helps identify the applicable utility and authority process, but it does not determine the condition of the piping. The useful questions come from the property, the work and who controls the system.

For a detached home, share the original construction era, known renovations, additions, suites, appliance relocations, capped lines and available permit or service records. Construction age can prompt questions, but it does not prove that gas piping is original, defective or suitable for a particular test scope.

For a townhouse, apartment or other strata property, identify whether the concern appears unit-specific or may involve shared piping, common property, building shutoffs or access controlled by the strata corporation or property manager. Authorization and notice requirements should be confirmed rather than assumed.

If a utility, inspector, insurer, realtor, buyer, lender or other party requested the test, ask for the exact wording of the requirement. That wording can affect the scope and record needed, but the requesting party remains responsible for deciding whether the result is acceptable.

How to Prepare for the Pressure-Testing Visit

Useful information before booking includes:

• Why the test is being requested and what decision the result must support.
• The service address, property type and whether the home is detached, contains a suite or is part of a strata.
• Whether gas is currently on, off or locked. Do not operate the meter or remove a lock.
• Which gas piping, appliance, renovation, repair or event is connected to the request.
• Available permit, inspection, utility, repair, installation or property records.
• Any written requirement from an inspector, insurer, realtor, buyer, lender, strata corporation, property manager, utility or authority.
• Access conditions around piping, shutoffs, mechanical areas, crawlspaces, suites and the work area.
• Household needs that could be affected by an interruption, including essential heating or a separate suite.

You do not need to diagnose the system before calling. Describe what changed, why testing was requested and what information the requesting party expects. Do not remain in a hazardous area to collect details or photographs.

Tell us why the test is needed, what piping or work is involved, whether gas is on, off or locked, the property type and any written requirement or reference number you received. We can use that information to define the service conversation and identify questions that must be confirmed for the property.

If natural gas or carbon monoxide is suspected, follow the emergency instructions above instead of booking a pressure test from inside the property.
