Arrived to the home, client had recently just purchased this home and are currently moving their stuff in. There is an existing ventless gas fireplace that the client had a company come out to clean it and they stated that there is a leak. I turned the gas cock on and discovered that there is a pinhole leak in the really small, appliance sized gas flex. I advised to the client that this flex may need to be ordered due to the sizing of the flex. I provided options and client will reach out to us with their decision on what they would like to do going forward.
