I don’t know about anyone else but I’m learning a bunch from this thread. I didn’t know you paid more by swapping tanks. I guess it makes sense but I didn’t know it. Do the tank swapping companies keep the 10 under the 10 year certification limit?

You will usually pay more by swapping tanks, but it depends on the places available to fill tanks. Some charge by the weight, i.e. gallons, but others charge by the fill. So if you take in a partial tank, they would charge you for a fill, regardless of how much they actually put in.

Yes, the exchange places only have tanks with 15 lbs. rather than 20 lbs. Rhino started this a few years ago as a money grab, and now they all do it. There is a local filler here who will try to tell you that it isn't legal, or safe, to fill them past 15 lbs.! Just a simple money grab, as he charges by the fill, and not by the gallon. Total ripoff.

Here in the PNW, they fill by the gallon and I have always only been charged for what was added to the tank. Our 30# tanks have taken 7.2 gallons before, usually between 6.9 and 7.1.
DW prefers cooking with gas, and we use for quick recovery of hot water. We use about a 30# tank a month.
