Natural gas provides an efficient source of energy for households. Tankless water heaters that use gas can provide a steady supply of hot fluids on demand. Though nontoxic, natural gas may combust when it makes contact with ignition sources, and leaks may also cause other unpleasant and potentially dangerous problems for your home. Here's how to tell if you have a gas leak that might require water heater repairs or emergency assistance from your utility company. 

4 Signs of a Gas Leak

1. Odors

Though natural gas is usually odorless, manufacturers add mercaptans, or sulfur compounds that have a pungent odor similar to rotten eggs. This is a safety feature that can quickly alert homeowners to a leak, giving you time to vacate the premises and call for help. If you notice a foul aroma that smells like sulfur, call your gas company to inspect the lines and perform any necessary repairs. 

2. Hissing Noises 

When holes or fissures form in gas lines, you might notice hissing sounds. This occurs when gas gets forced out of small openings, resulting in a high-pitched noise. You might also notice hissing due to loose connections between the gas line and your water heater. A water heater repair technician can tighten the connection, or a utility company may replace damaged line segments to stop the leak. 

3. Wilted or Dead Houseplants 

Plants take in carbon dioxide (CO2) and use energy from sunlight to convert it into sugar, which provides them with food and energy. When natural gas leaks into your home, it displaces carbon dioxide and prevents houseplants from completing photosynthesis, causing them to wilt or die. Your gas company can locate the source of the leak and patch it to keep your indoor plants healthy. 

4. Physical Symptoms 

Similar to the way it displaces carbon dioxide, natural gas can displace oxygen when lines leak. In enclosed spaces, a lack of oxygen can cause hypoxia symptoms, including headaches, blurred vision, and shortness of breath. As soon as you notice these symptoms, evacuate your home and seek medical attention before calling for repairs.
