I recently filled up my father-in-law's propane barbeque tank in Palm Springs. It was filled but I was told it wouldn't be long before I couldn't.
You see we have a new standard for the valve here in California. You must have a triangular knob, not a round one. Supposedly this new valve has some safety feature. I suggested at dinner that I am so cynical that I believe some tank or valve manufacturer paid off, err, contributed to Davis and his pals to change the law and outlaw all existing tanks. That couldn't be...could it?
Its a Federalrequirement effective 4/1/02. Its not so much the shape of the spigot, but that it shows the propane bottle has an over-fill protection device. Such a device prevents te tank from filling more than 80% to allow for expasion of gases. Its a safety issue. Not related to California at all
