30 gallons are the smallest commercial bottles that are not required to the OPD.

If you upturn a OPD - it turns off. Cannot dump liquid from a OPD into an old tank.

When you buy a new tank - be sure the tank is dumped by the propane company.
The internal gas won't burn and it just fills it. They have a special tool
that allows dumping.

We use one 20 to power our Drott Go-Devil, and dad refills his camping
bottles as well.

"Steve B" quickly quoth:


I ALWAYS inverted my tanks. The big tank will sit nicely on its collar
on a
wood picnic table, with the smaller tank at a right angle.

I thought the OPD valves on new tanks prevented overfilling OR any
possible liquid propane discharge. Am I wrong? I'd rather refill
my old 1 pound tanks if possible.


Well, you will notice past tense. It shows how long it has been since I
refilled any of the tanks.

BTW, someone here said if you label the old tanks "FOR CUTTING ONLY" that
you can get them refilled.
