How should plumbers check for gas leaks?

If you suspect a gas leak in your home, acting fast and calling a licensed Atlanta plumber is crucial. If left unaddressed, gas leaks are dangerous and can lead to serious health risks, fires, or explosions. Certified plumbers in Atlanta, including those serving Fulton, DeKalb, Cobb, and Gwinnett counties, use advanced tools and techniques to detect and repair gas leaks. Here’s how they do it:

Using Gas Leak Detectors

Professional plumbers rely on specialized gas leak detectors to identify combustible gases like methane and propane in the air. These devices use semiconductor sensors or infrared technology to detect even small traces of gas. If a leak is present, the detector will trigger an alarm, allowing the plumber to pinpoint the affected area.

Performing a Thorough Visual Inspection

A plumber will inspect all gas lines, fittings, valves, and appliances, such as water heaters, furnaces, and stoves. This is particularly important in older homes in historic areas like Virginia-Highland or Decatur, where aging infrastructure may increase the risk of leaks. The plumber will check for corrosion, loose connections, and physical damage that could allow gas to escape.

Conducting a Pressure Test

Plumbers may perform a pressure test to assess the integrity of your gas lines. This involves shutting off the gas supply, sealing the system, and using a manometer to measure pressure levels. If there is a pressure drop, it indicates a leak somewhere in the system. This test is beneficial for detecting hidden leaks in underground or behind-the-wall piping, which are common in suburban homes like Sandy Springs, Roswell, and Alpharetta.

Soap Bubble Testing for Small Leaks

For more minor leaks, plumbers often use a non-toxic soap solution applied to joints and fittings. If bubbles form, it confirms a leak. This method is commonly used for quick diagnostics before proceeding with more advanced repairs.

Repairing or Replacing Damaged Components

Once the source of the leak is identified, the plumber will determine whether repairs or complete replacements are necessary. They may need to replace corroded pipes, faulty connectors, or appliance valves. They may sometimes recommend upgrading outdated gas lines to meet modern safety standards, particularly in older Midtown and East Atlanta properties.

What to Do if You Suspect a Gas Leak in Atlanta

• Evacuate immediately. If you smell gas or suspect a leak, leave the building immediately.
