Fill the cup with water and squeeze in a small amount of dish soap. Stir the soap and water together until it starts to form suds.  You can use any liquid dish soap to test for a gas leak. If you don’t have dish soap, you can substitute a liquid laundry detergent instead. Dip a small paintbrush into the soapy water so the bristles are completely coated. Paint a thin layer of the water around the pipe connections where you think there may be a leak. Brush the water around the whole connection point so it’s saturated. Any gas leaking from your pipe connections will make bubbles in the soapy water. If bubbles don’t form at the connection, then the gas leak is in a different place on your pipes. Continue brushing the water and watching for bubbles until you find the source of your leak. Use a pencil or a marker to draw on the pipe where you found the gas leak. Once it’s marked, contact your utility company and let them know that you have a leak in your home so they can fix it. Don’t attempt to fix gas lines yourself if you’re inexperienced.
