We’re not from the Government, but we are here to help you.
Because the Government has already been ‘helpful’ in regulating your propane tanks. We just discovered this year that the new type, with the overfill protection feature, is only good for 12 years, and then must either be replaced, or recertified.
Prior generation tanks cannot be refilled by any propane station. The new type have their date of manufacture stamped on the collar/handle rim.
Both of ours were made in 2002, and we can only get one more fill-up before we have to replace them. You should check the dates on yours so you don’t get any surprises the next time you head over to get yours refilled an hour before you want to grill that 3 pound prime porterhouse.
If you only have one tank, and it’s pretty old, you might as well go buy a new one now, and have it filled, so you have a backup when the old one goes empty in the middle of cooking. We hate when that happens.
