Had a bunch of 5 and 10 lb tanks that just needed revalving (about $25 at a dealer) but only found a home for one of them. Still have a few but will not deliver.....

I'll keep that in mind when I get up that way. Hoping to get after some specks toward the end of the month.
I'll PM you
I haven't priced them in the US yet, but heading down on Thurs and will look at WalMart and TSC there.
My wife uses the tall metal bottles in her hobby fixture....so I priced those at Wally World U.S today.. they're only $2.67 U.S. so I bought 1/2 dozen. A 2 pack of the 1lb stubbies was only $6. Heck of a deal comparatively.
If you cut a tank apart you will find that the relief valve extends down into the tank so it starts to spirt well before the tank is full of liquid. If you leave it in the hot sun and the valve starts to vent, well it is just doing its job....
If you shut the main tank off just as propane is beginning to spurt, they are not overfilled. When weighed, they are less than full.

In actual fact, if you fill until it spits from the valve, it is over filled. A propane cylinder is considered full when it contains 80% of it's water capacity. On a refillable cylinder, the dip tube, the end of the spitter valve, goes far enough down to reach the liquid when it is at the 80% level. The relief valve on the 1 lb cylinders don't go that low, they will spit out propane at close to the 95% level leaving only 5% for expansion. You can compress a gas, but not a liquid, so as the propane expands due to heat it quickly fills that 5% leaving no place to expand. At that point the cylinder is filled with liquid which can't be compressed so the pressure rises very rapidly opening the valve and releasing the propane liquid, which then expands by 270 times the volume of the liquid.
Of course once the cylinder has been used and the level drops, this isn't an issue, but transporting after filling,,,,, one never knows just how much is in there.
Be safe.
Haven't seen a refillable one pound bottle since the days of drive in theatre heaters.....LOL
Well that bought back a memory....going with 5 kids to the Drive-In in Lethbridge Alberta in our 1960 Rambler Station Wagon. I vaguely remember a heater, don't remember if it was elec or gas....Thanks Pat !!
