Recently I did an inspection where the gas line was under the house in the crawl space. The line is black steel and somewhat rusted (see photo). It appears to be more than just surface rust. Rather than make a call as to whether there was an actual problem or not, I recommended further investigation by the utility company. I got a call from an upset realtor because she thinks I recommended replacing the line. Maybe I’m second guessing myself now. I am a newbie at this. What would you have done? Did I overreact?
