Propane BBQ problem
So my propane bbq has a gas leak. I feel pretty confident that the leak is at the tank valve to the bbq hose connection. I unhooked the hose, cleaned the inside of the tank valve connection point (all metal), cleaned the connections on the hose (metal interior pipe, and plastic treaded outer connection). I don't see anything out of the ordinary.
BBQ is about a little over a year (Weber) and the tank might be more like 5 years.
So....what do I do next, or what do I replace first? Tank or hose?
