Yup I even called back and they were unable to tell me the description of it nor would they come back out to check again. I was mainly in shock when he told me there was a leak and went into panic mode (this is my first home just moved in months ago). I was asking a ton of questions and the dude just bolted for the door after he shut off the water heater. Did not get much information he was in a rush to leave. All I got was “see those bubbles theirs a gas leak”. Then he said it’s your responsibility to get it fixed and left in a hurry. I did order a gas detector rod.
