​
How Our Licensed Technicians Detect Gas Leaks in Markham
Accurate Gas Leak Detection is the First Step
At JLN HVAC Solutions, every gas line repair begins with correctly identifying the issue. Our licensed gas technicians use a combination of advanced tools and proven methods to detect leaks efficiently and safely. For larger leaks, we conduct a pressure test to evaluate the severity of the problem.
To pinpoint the exact location, we use a leak detection solution—such as soapy water—that forms visible bubbles at the site of a leak. This method is simple, safe, and highly effective, even for leaks that aren’t immediately visible.
Performing the Pressure Test
Our pressure test service is a vital part of ensuring your gas line system is safe and leak-free. The process begins with our licensed gas technicians carefully isolating the gas meter and all connected natural gas appliances. This step is essential to prevent any potential damage to appliance regulators during testing.
Once isolated, we perform a thorough “stress test” by pressurizing the gas supply line with air—applying approximately 60 times more pressure than what is typically released by the gas meter. This high-pressure method allows us to identify even the smallest leaks that could pose future risks. The industry-standard requirement for this test is 15 PSI sustained for a minimum of 15 minutes.
During this time, our technicians closely monitor the pressure to ensure there is no drop, confirming the integrity of the line. This rigorous approach gives homeowners and business owners peace of mind, knowing their gas line system has been carefully inspected and is operating safely before repairs are made or gas service is restored.
​​
Compliance: TSSA codes 4.3.7
Compliance: TSSA codes 4.3.7
It shall be the responsibility of the installer of a gas piping system to perform pressure tests in accordance with Clause 6.22.2 and to ensure that the piping or tubing system is gas-tight at the completion of the tests.
As licensed gas technicians, we follow strict Technical Standards and Safety Authority (TSSA) requirements. According to TSSA Code 4.3.7, every new or repaired gas line must be properly pressure-tested to ensure there are no leaks.
​
Before completing any gas line work, we perform thorough pressure testing — as required by TSSA Clause 6.22.2 — to confirm the system is completely gas-tight and safe to use. This protects your home and ensures all work meets the highest safety standards.
​​
Repairing Gas Leaks
Once a leak has been identified, our licensed gas technicians proceed with precision repairs to ensure the gas supply line is fully sealed and secure. We use approved materials and industry-standard techniques to eliminate the leak and restore the integrity of the line.
After completing the repair, we retest the system to verify that the issue has been resolved and that the line can safely handle normal operating pressure. Safety is our top priority, and we don’t consider the job complete until we’re confident the system is leak-free and compliant with all local codes and regulations.
​​
U-Gauge Manometer Test​
​A U-gauge manometer test is a precise method used to measure gas pressure within a system, ensuring it falls within the safe and optimal operating range. The device consists of a U-shaped tube filled with water or specialized manometer fluid. When connected to the gas line, the difference in fluid levels between the two sides of the tube indicates the pressure in the system.
At JLN HVAC Solutions, our licensed gas technicians use this method during diagnostics and after repairs to confirm that gas pressure is correct and that no leaks are present. It’s an essential step in verifying the integrity of the gas line and ensuring your appliances operate efficiently and safely.
​
Final Testing and System Check
Once repairs are complete, our licensed gas technicians perform a thorough inspection of the entire gas system, including all connected appliances. Each appliance is tested to ensure it ignites properly and operates as intended. We closely examine flame characteristics, burner performance, and overall functionality to confirm safe and efficient operation. This final step guarantees that the entire gas line system is working correctly and meets all safety standards before we consider the job done.

Top Causes of Gas Line Leaks in Markham Homes
Gas leaks can be dangerous and often go unnoticed until there’s a serious risk. At JLN HVAC Solutions, we’ve seen firsthand how small issues can lead to major problems if left unaddressed. Here are some of the most common reasons gas lines start leaking:
​
1. Aging Pipes and Connections
Over time, gas lines naturally deteriorate. One of the most common causes of leaks is aging pipe fittings and joints. The sealant used during installation can dry out, crack, or break down—especially under pressure or changing temperatures. As the sealant fails, tiny gaps can form between the threads, allowing gas to escape. Older piping systems are especially vulnerable, which is why regular inspections are essential in homes over 15–20 years old.
​
2. Corroded Pipes
Gas pipes can corrode when they're exposed to moisture, especially where the line passes through the foundation or sits outside unprotected. Over time, unpainted or unwrapped sections can rust, eventually weakening the pipe and causing dangerous leaks. We often find corrosion on pipes running under decks, patios, or through concrete walls. These areas should be protected with rust-proof paint or wrapped with electrical tape to prevent exposure. If your gas line hasn’t been inspected in years, corrosion could be a hidden risk.
​
3. Loose Fittings or Faulty Connections
Leaks often occur at connection points where gas lines join appliances or other sections of pipe. These problems are typically caused by improperly tightened joints, worn-out fittings like unions, or poor-quality installation work. Over time, even small shifts in the piping can loosen connections if they weren’t properly secured from the start. That’s why it’s critical to have all gas line work done by licensed technicians who understand how to properly seal and pressure-test every joint.
​
4. Leaking Gas Appliances
Sometimes the gas line itself isn’t the problem—it’s the appliance it’s connected to. Furnaces, stoves, water heaters, and dryers can all develop internal leaks over time. Worn-out gas valves, cracked fittings, or faulty regulators within the appliance can allow gas to escape, often going unnoticed until there’s a strong odor or warning sign. That’s why part of our diagnostic process always includes checking the appliance itself—not just the supply line—to ensure the entire system is safe and sealed.
​
5. Rodent or Pest Damage
In rare cases, rodents or pests can chew through flexible gas connectors or the insulation surrounding gas piping. This type of damage usually occurs outdoors—especially with BBQ gas lines—where flexible connectors are more exposed. Even a small puncture or tear can result in a dangerous gas leak. During inspections, we always check exposed sections of gas line for signs of chewing or wear, especially near decks, patios, or sheds.
