Rotten-Egg Smell
Natural gas is naturally odorless, but an odorant is added to make leaks easier to recognize. A sulfur-like or rotten-egg smell may indicate escaping gas.

A gas leak can create a serious safety risk for your home or commercial property. Natural gas and propane leaks may occur around gas supply lines, appliance connections, valves, and other parts of a gas system.
Recognizing the warning signs is important. A rotten-egg smell, unusual hissing sound, or damaged gas line may indicate a possible gas leak.

Gas systems may use natural gas or propane to operate equipment such as:

Recognizing possible gas leak symptoms can help you respond appropriately.
Natural gas is naturally odorless, but an odorant is added to make leaks easier to recognize. A sulfur-like or rotten-egg smell may indicate escaping gas.
An unusual hissing or whistling sound near a gas pipe, valve, or connection may indicate gas escaping under pressure.
Unexpectedly dead or discolored vegetation near an underground gas line may indicate a possible underground leak. Other soil and plant conditions can also cause this symptom.
Persistent bubbling in standing water near a gas pipeline may be a warning sign of escaping gas.
Visible damage, corrosion, or deterioration around gas piping and connections may indicate a potential safety problem.
Never try to confirm a gas leak using a flame, lighter, or other ignition source.
Gas leaks may develop in different parts of a property’s gas supply system — from the main supply line to individual appliance connections.

Gas pipes transport fuel from the supply source to appliances and equipment. Damaged or deteriorating sections may allow gas to escape.
Joints, fittings, and connections may develop leaks due to wear, damage, or improper installation.
Valves control gas flow throughout a system. Damaged or deteriorated valves may become potential leak locations.
Gas stoves, water heaters, dryers, and other appliances depend on properly connected gas supply lines.
Buried gas piping can be affected by corrosion, ground movement, excavation damage, or deterioration. Locating buried utility lines is also covered under Underground Main Line Tracing.
