What Is a Certified Gas Pressure Test?
A certified gas pressure test—also known as a pressure leak test—is a mandatory procedure to verify that your gas lines are leak-free and meet safety standards. It ensures the integrity of the gas piping system by detecting leaks and validating system pressure stability.
This test is typically required in several scenarios:
When restoring gas service after it has been shut off for an extended time
During a BGE gas meter installation or relocation
After modifying or replacing parts of the gas piping system
As part of the permitting process for property renovations or additions
When buying or selling a property, especially older homes with outdated infrastructure
Without this test, gas utilities such as BGE (Baltimore Gas and Electric) will not reconnect gas service, making it a non-negotiable part of your project timeline
Who Is Qualified to Perform the Test?
In Baltimore City and neighboring jurisdictions, gas pressure testing must be performed by a licensed master or journey gas fitter. This isn’t a job for a handyman or a general contractor—it requires licensed professionals trained in gas safety standards. Key qualifications include:
Valid Maryland Master or Journey Gas Fitter license
Authorization to pull gas permits in Baltimore City
Knowledge of International Fuel Gas Code and local amendments
Familiarity with BGE protocols and submission procedures
Hiring the right professional ensures not only safety but also compliance, preventing delays or violations that could cost time and money. Learn more about our certified gas pressure testing service.
Step-by-Step Breakdown: The Gas Pressure Testing Process
Let’s explore what’s involved in a BGE certified gas pressure test from start to finish. This comprehensive process ensures the gas piping system is airtight and code-compliant.
1. Permit Application
Before any testing begins, the contractor must apply for a gas permit through the Baltimore Department of Housing & Community Development. The time required for approval can vary depending on:
The completeness of the permit application
Additional documents or clarifications requested by the city
The current workload or backlog at the permit office
This step is often the first bottleneck. If the city requires engineering drawings, specifications, or prior inspection reports, it can add days or even weeks to the timeline. Staying proactive and responsive during this step is essential.
2. Gas System Isolation
After the permit is approved, the technician begins by isolating the gas system. This involves:
Disconnecting all gas appliances
Installing test caps and plugs to seal the system
Shutting off service at the gas meter or upstream valve
At this point, the system is sealed off to prepare for air pressurization. This is done with precision to ensure accurate readings and to prevent air leakage during the test.
3. System Pressurization
With the system isolated, it’s filled with air and pressurized using a 30-pound test gauge. In Baltimore City, the system is typically filled to 20 psi, which is standard practice.
This pressure level is ideal because it allows even small pressure losses to be observed. The air is held in the system for a full 24 hours, a Baltimore City requirement. This waiting period is critical. Even a minor drop in pressure indicates a leak, which must be repaired before the system can be approved.
4. Leak Detection and Repair
If pressure drops during the 24-hour test, it signals a leak. The technician will use tools like:
Soap solution applied to fittings and joints
Ultrasonic leak detectors
Manual tracing along the piping network
Leaks can be as simple as loose connections or as serious as corroded or cracked pipes. Once identified, repairs are made, and the test is restarted. This cycle repeats until the system passes.
5. City Inspection
Once the system holds 20 psi without pressure drop for 24 hours, it’s ready for inspection. The contractor schedules a visit from a Baltimore City plumbing inspector. During the inspection, the inspector will:
Observe the gauge for approximately 15 minutes to verify stability
Perform a visual inspection of the gas piping layout
Check for proper supports, labeling, and code compliance
Confirm that no unauthorized modifications or unsafe conditions exist
This dual inspection—gauge and visual—ensures both functionality and structural integrity of the gas distribution system.
6. BGE Notification and Certification
After the city inspection is passed, the contractor submits the final paperwork to BGE, including:
Inspection approval confirmation
Test results and pressure logs
Permit number and completion report
BGE then reviews the documentation and schedules a technician for gas meter installation, reconnection, or relocation, depending on the service request.
7. Gas Service Restoration
Finally, BGE dispatches a crew to restore service. This includes:
Installing or re-installing the gas meter
Reconnecting the supply line
Turning on the gas and purging the lines
BGE technicians will not perform this step unless all prior testing and documentation is approved.
8. Appliance Reconnection and Start-up
Finally, a licensed plumbing company, such as Stokes Plumbing & Mechanical, will reconnect the gas distribution system to the gas meter, re-light all gas appliances, and coordinate a final inspection with Baltimore City mechanical inspectors.
Why This Process Matters for Your Property
Gas leaks can result in fires, explosions, or carbon monoxide poisoning—all serious and potentially life-threatening hazards. A certified gas pressure test minimizes these risks by identifying issues before gas is introduced. For homeowners, it’s peace of mind. For property managers and real estate investors, it’s a necessity:
Compliance: Required by law before BGE will restore gas
Safety: Prevents gas-related accidents and property damage
Documentation: Useful for insurance and future real estate transactions

Common Roadblocks and How to Avoid Them
Permitting Delays: Always verify with your contractor that all necessary documents are submitted with the initial permit application. Include diagrams, specifications, and prior approvals to minimize rejections.
Hidden Leaks: Old or poorly installed piping may have invisible flaws. Consider scheduling a pre-test system inspection to find issues early.
Scheduling Conflicts: City inspectors and BGE technicians are often backlogged. Book appointments as soon as possible and build buffer time into your schedule.
Incomplete Test Setup: Improper pressurization, incorrect gauge size, or leaky test caps can cause test failures. Always use experienced professionals with the right equipment.
