I got a smoker for Christmas and recently got around to using it. Instead of purchasing a second propane tank I just removed and used the tank from my Weber grill. When I went back to use the grill it leaked propane right by the regulator. Thinking I accidentally broke it when removing the tank I got a new one under warranty. New one did the same thing. Connected the tank to the smoker and no problem, went back to the grill and it instantly leaks. Tried a brand new tank and it connects perfectly to the grill. Obviously I’m going to leave the new one connected to the grill, and use the other when I smoke. But anyone have any idea why this would have occurred? Sorry for the long post, thanks.
