    Sounds like you are looking for a pretty big leak or multiple leaks.

    There is shut offs at each heater, but they are after or downstream of regulators for each heater so i guess i need to keep the psi low. I had to schedule a boom lift for Tuesday next week. I also noticed that the tube heaters are Coray Vac and the last time I worked on one , 10 or many more years ago I found it tough to find parts. I like the steady work idea if I didnt have a heap of other jobs that need done. Thanks for the input. Ill know more next week.

    I would use an air compressor set to the feed pressure the gas supply uses.

    So long as the piping is exposed this should be a fairly quick job.

    Also if the supply pressure is a couple psi, see if you can arrange to have a total plant shut down.

    Ive done this on pneumatic system leaks in the past.

    As soon as it was quiet, I could here the leak.

    A couple years ago, I had a nightmare gas leak. Gas was locked off, and there was a huge leak. Could not even hold pressure more then a few seconds.

    All piping was buried in the walls and floors of an apartment building.

    Took days, ultimately used a smoke machine and pumped it into the piping. Had it narrowed down in a couple hours at that point.

    The leak was a wide open pipe covered up by a flooring contractor over the summer during a rehab.
