Tracking Down a Mystery Gas Leak
Kevin Hilton is one unhappy homeowner. He lives in a house only one year old so plagued with air leaks that he went ahead with an energy audit to help track them down. In the process he discovers another problem: an apparent natural gas leak that shows up when the house is depressurized during a blower door test.

Turn the blower door test equipment off, and the leak is undetectable, he writes in a post at the Q&A forum at GreenBuildingAdvisor. The plumber who put the gas lines in can’t find the source of the problem, and now Hilton isn’t sure what to do.
Hilton gets several suggestions for tracing the source of the leak. He also gets an alternative theory about where the gas is coming from, along with a strategy for testing it that involves nothing more than a few bottles of peppermint extract from the grocery store.
Hilton’s unusual problem is the topic for this week’s Q&A Spotlight.
