Common Gas Line Problems

Natural gas offers homeowners a safe way to power appliances (such as stoves or ovens) and heat their homes. However, your gas line can develop issues and expose you and your family to risks of fire and explosions. 

Check out several gas line problems that you should look out for to help you stay safe. 

Gas Line Blockages 

Gas line blockages are a common occurrence for most homes. Often, blockages are due to the buildup of contaminants in the gas line, debris stuck at the gas line access point, or a tree root invasion. As a result, little or no gas flows into your gas-powered appliances. 

The primary causes of gas line blockages are:

• Water. Water can cause rust and corrosion in underground natural gas lines, which ultimately clogs them.
• Dents. Sometimes the gas line can suffer dents or kinks, which restrict gas flow. 
• Pest invasion. Dirt and insects can find their way into your pipelines through the smallest cracks or spaces and block your gas line. 

Some obvious signs of a blocked gas line are low flames in your gas stoves or a lack of hot water from the water heater (even when you crank up the temperature). Gas line blockages can be extremely risky. So, have your plumber repair the gas line clogs immediately to avoid damage to your appliances or an accidental gas explosion. 

Gas Line Leaks

Leaks usually develop when your gas lines corrode and burst. Extreme winds and hurricanes can also cause leaks if the resulting damage extends to the gas lines. Additionally, poorly maintained appliances can malfunction over time and start to leak. Incorrectly installed fittings, low-quality gas lines, old valves, and faulty pipe threads are also culprits for gas leaks.

Some sure-fire signs of gas leaks in your home are: 

• Rotten egg smell. Natural gas has a mercaptan additive, which gives the odourless gas a sulphur, sewage, or rotten eggs smell. 
• Dead plants. If plants or vegetation in your yard die without reason, an underground gas line leak may be to blame.
• Broken pilot light. If your appliance's pilot light snuffs out constantly, you probably have a gas line leak. 

If you detect a gas leak in your home, don't use a match, lighter, or appliance because a tiny spark can lead to an explosion. Also, open the doors and windows, evacuate immediately, and stand several yards away from the building. Afterward, contact a professional gas plumber to fix the leak.
