LP tank Re qualifying?

[roger n cindy]

thanks tom and john, the little bit of noise is annoying to me just glad to know its programed in rather than something broken. our insulation is settled, i pulled an interior pannel out and theres only about 1/3 coverage. when we reinsulate we probably wont hear it at all.

I haven't noticed any noises of any kind from the Worthington aluminum LP tanks on either my '64 Overlander or '78 Minuet. The Overlander has three-year-old 40 pound Worthington aluminum LP cylinders that came with the new OPD style valves while the Minuet has original 20 pound LP cylinders that were fitted with new OPD valves when the tanks were recertified about 18-months ago. While I haven't noticed it having been discussed lately, there was a problem with some valve switch-overs using OPD valves with the incorrect dip-tube length (the aluminum cylinders use a different valve when compared to the same capacity steel tanks) - - I don't know whether an incorrect dip-tube length could cause audible noise or if it might be OPD valves of varying manufacture having different operational characteristics.
