    On our last trip of the season we started hearing a strange sound when the propane was on and being used (only happens when something is running on the propane.)

    I was able to capture the sound in a video. I assume it’s coming from the regulator. But before I go replace the regulator I’m hoping someone can be like “yep, that’s a failing regular - replace it and you should be good.”

    I’m very curious to see what it is. I’ve never heard anything like. It reminds me of a sound Hollywood uses on spaceships. :p[%]

    Before I buy a new regulator, I'd try to pinpoint the source of the noise. It sounds like its coming from the tank rather than the regulator. Sometimes when I get a new tank for the grill at home gas doesn't want to come out like it should. I usually shut off the tank tap on the brass valve on the tank with a small hammer or whatever is handy. If that doesn't work, I'd try a different tank.

    If you hold the regulator, can you feel it vibrate?

    I had a sound. Constant like that. It ended up being the propane cylinder. I moved it to the grill and the noise followed the cylinder. When the tank was empty, I exchanged the tank.

    Good notes everyone! We had an older tank on it (from prior owner, not sure how old) and it was making a bit of sound so I replaced with this new tank. Then we got more sound! So I guess it could be the tank, but I'm somewhat uncomfortable with strange sounds coming out of the system that involves flammable gas.

    The sound is strange, partially because of the pitch and how close the tank and regulator are I haven't been able to isolate it to one or the other. I guess if I got my head between the two I should be able to do it. I'll try again.

    Similarly the regulator looks like a cheap one and from the prior owner, so might be worth replacing anyway.

    Thanks so much for the help.

    You can use a short piece of hose as a stethescope to isolate a sound. Hold one end to your good ear and pass the other over the general area until you get it localized. Shade tree mechanics used to use this method to isolate misfires and exhaust leaks.

    I had a noise similar (but different) only when it was cold out. It turned out to be a leak in the hose. It was suggested that I spray the entire area with soapy water to see if it was a leak or not. Answered the question very quickly.

    Update!

    I finally got around to working on this as we do spring maintenance on the trailer. Turned out to be the pigtail. I got a cheap mechanics stethoscope off Amazon and it's my new favorite tool. Helped me find the source of the sound. And replacing the pigtail was cheap and easy.

    Thanks everyone for the tips!
