I think it is every 10 years you need to do a re-cert. My 20 lb tanks I exchanged when it was time to re-cert. Got some 2017 tanks in exchange and then went back to refilling the tanks at $12 per 4.5 gl/ 20 lbs after the 15 lb ran out.
I thought about the 1.2 gl/5 lb tank, but the re-cert has been my concern. I got a y connector for my 20 lb tank on the TM and a 20 ft hose with a 1 lb adaptor. But a few years back. I realized I only use about 4 - 1 lb tanks a year. I get them 2 for $6, so I stopped using the y connector and hose.
