How to Diagnose a Natural Gas Leak

Method 1: 

Determine whether the gas is leaking by smelling it: Natural gas contains hydrogen sulfide, which smells like an unpleasant rotten egg smell. If there is no smell after closing the gas meter valve, it can be judged that there is a leak behind the gas meter valve (such as Gas meters, hoses, interfaces, etc. between gas meters and stoves and water heaters are connected).

Method 2: 

Use the gas meter to determine whether the gas is leaking: When no gas is used at all, check whether the numbers in the last red box of the gas meter move. If they move, it can be judged that there is leakage behind the gas meter valve (such as gas meters, stoves and The hose, interface, etc. between the water heater and the gas meter).

Method 3: 

Use soap or washing powder to make soap liquid with water for inspection: Apply it to gas pipes, gas meter hoses, valve switches and other places prone to gas leakage in turn to check whether there is a gas leak in the home. If the soap liquid encounters a gas leak, the leaked gas will blow out foam. When you see foam generated and increasing, it indicates that there is a leak in that part. At this time, you must take immediate measures to prevent the gas from continuing to leak.

Method 4: 

Use a gas alarm instrument (such as a household gas leak alarm) to check for leaks. Be sure to purchase it at a specialty store or regular place.

Expanded information: There are six main reasons for gas leakage: first, the hose connecting the stove is aging and cracked, or both ends of the hose are loose and falling off; second, when ignition is unsuccessful, unburned gas leaks directly; third, When using gas, boiling soup or boiling water extinguishes the fire, or the wind blows out the fire, causing gas leakage; fourth, gas leakage occurs because the stove door is not closed tightly when turning off the fire; fifth, pipeline corrosion or gas meters and valves , The interface is damaged, causing air leakage; sixth, the gas stove is leaking.
