It has been burning in the back of my mind for days now, and 37Chief's post, almost got highjacked. It set me off. The first of the week, I needed to fill my 100 lb propane bottle, and took it to the feed store, to get filled, and was told that it wouldn't be filled, till I had it recertified. they told me where to go in Spanaway, to get it recertified. I didn't want to drive 15 miles, to Spanaway, so I took it to a Chevron station in Yelm, that I was sure were pretty lax on checking dates. Sure enough the lady who was going to fill it, didn't check it for date, and started to fill the bottle. Every time she tried, propane would leak out around her filler valve. She finally told me that I had a bad valve and needed to take it in for recert. SOOOO I drove to Spanaway and went to get a Recertification. The guy at the propane Co. set the bottle down on the drive in the bottle filling area, and told me it would cost $ 7.00, plus gas to fill it, never once looked the bottle over, and filled it, and grabbed a electric vibrating pencil, and scratched some illedgeble stuff on the top shield, and sent me on my way, after of course paying for the gas and recert. The only saving grace to the whole fiasco, was the cheaper propane price. Don't professionals care if a bottle is bad? Or if it blows up on me? Why no testing procedures? OH by the way, my valve was good, but as I found out later, the filling hose at the Chevron station, had been dropped on the concrete drive, and had a big owee on the brass nipple.
