AmeriGas is a company that should lose their license. Their service people do not check for gas leaks. They do not allow you to speak to anyone but a call center in Africa. My regulator was leaking. Probably for about a year, and a decent service person would have smelled the leak. Took over a week to get an appointment, but then the service person did not show. I usually fill my 120 gallon tank twice a year. This last 12 months, was filled 5 times and we were out of the country for a third of that time.
