I have been using my BBQ for decades..currently a
Weber Spirit. When the bottle is near empty..it weighs in at 18 pounds..maybe slightly less. When the bottle is getting low I weigh it on my digital bathroom scale. Don't want to get caught empty in the middle of a meal.
All's well. The other day I went to my Propane supplier for the last 30+ years . While charging the bottle..The guy doing the recharge put a screwdriver to a little "blead screw" on the side of the bottle valve. Never noticed this procedure before. I asked him about it and didn't get much of an answer.
When I got home I weighed the "Full" bottle. (Never done that before) It weighed 35.2 pounds. My impression was it should weigh 38+ pounds. 18 pounds for the empty bottle + 20 pounds for the propane.
Is this Normal..?
