How to Find a Broken Gas Pipe Under the House

A suspected gas leak should never be ignored. If you think you can smell gas, you should investigate immediately no matter how faint the aroma. A gas leak that's left unchecked can cost lives. If you use propane or natural gas in your home, it's wise to have a gas leak detector on hand, especially if you live in area that's hard for your gas supplier to reach quickly.

  Turn on your gas leak detector and search for the source of your suspected leak if you have access to the pipes below your house. Your detector will tell you how close you are to any leak. As you approach the source of your leak, your machine will give a higher reading. Consult your detector's user's manual for specific operating instructions.
