I noticed the gas stove flame turned orange color instead of blue so I had the gas company come out and was told the gas pressure was very low so pipe was blocked some how. Plumber came out and eventually found water in a section of gas pipe buried underground. He hooked up his gas tank to the pipe and blew a couple of buckets of water out. Looks like the problem was solved. That was last winter. The problem came back again this winter when it got cold the gas stove flame turned orange. I have no idea if water got in through a leak (I don't smell any gas but then it's buried underground so maybe hard to smell if leak is small?) or if it's water condensation from the moisture in the gas. I may dig up and replace the pipe but my question is how to best insulate it to prevent any leak or condensation?
