How To Find A Gas Leak Under A House


The natural gas we use in our homes is usually safe, but in some cases, such as poorly maintained gas lines, gas leaks may occur. Even the smallest of gas leaks can be very dangerous, and it’s important to have your gas lines regularly inspected for leaks. Don’t worry though; with the right equipment, gas leaks are fairly easy to find and fix.

Detecting a Gas Leak

Most people detect a gas leak by smelling it. Gas suppliers add a sulfur compound, which smells like rotten eggs, to help people detect gas leaks in their homes. So, if you smell rotten eggs, chances are you have a gas that should be investigated right away.

Where To Look for Gas Leaks

Most gas leaks occur at the fittings and joints where the pipes join together. If they are disturbed or are not tight enough, leaks can occur. Sometimes, you may also find a crack or a pinhole leak along the gas line. This happens if the line is not well protected from the elements.

Finding the Gas Leak

First, you need to isolate where the leak is coming from. Is it from the yard or the house? Your gas provider is responsible for leaks on their side of the meter, and you are responsible for leaks from your meter to your home. Take a spray bottle with special bubble-maker water. Spray it on the gas line, especially on the joints and fittings where leaks mostly occur. If you see bubbles form, there is your leak. Remember, don’t smoke while doing this. If you can’t find the leak, call a professional plumber to perform a thorough test and fix it for you. Your plumber can pressurize the gas lines with air, access lines in the walls, and excavate lines underground.   Note that if the smell of the gas is very strong, you may be dealing with a big leak. In that case, leave the house immediately and call your gas supplier. They will shut off your gas. However, you should know that they will not turn on your gas supply until the leak has been identified and fixed, and inspected.
