Holy smokes, NRALIFR....that is a lot of very good reading. Thanks!
Ticki2:
Correct. Most countries have liquid propane tank certification laws, including Canada. Our tank was "looked at" only (by 2 plant employees no less), and simply re-filled.
I suspect that this propane recert "law" is utterly and completely unpoliced here....at least for RV propane tanks.
Many of my neighbors have enormous horizontal propane tanks to supply their fireplaces. I am curious. I will ask our neighbor about their large horizontal tank. A tank that I know is over 14 years old.
NRALIFR:
I bled (rather, purged) our horizontal cylinder myself (with a qualified gas tech), the first time it was filled. That end cap on the bleeder spigot is interesting. I can't recall if our tank has that. On edit: OK, I can remember now; I have no cap, and the screw is indeed exposed.
On edit: was the 12 year initial requalification period reduced from 12 years to 10 years in 2017? And, the subsequent requalification period lengthened from 7 to 10 years?
Also, a question to everyone: do you have your brand new propane cylinders "purged" before first filling?
