I've never really understood HOW the LP regulator is supposed to work, so bear with me!
My old LP tanks emptied out over the winter, so I upgraded the supply lines to the new OPD lines. I bought one 20# "Blue Rhino" tank from HD while I decided what size tank to use (20# or 30#'s - it came with two 30's). I ASSUMED (uh oh) that I could hook just one tank up, and leave the other hose unhooked while I figure out what tanks I will buy.
My first clue should have been that the oven burners just didn't seem to flame as high as the should have. Clue two was that the furnace just didn't seem to be getting very warm. I was thinking about clue two, and had mentioned to my wife that "either we had a furnace repair bill on the way....or maybe I didn't turn the tank on all the way....." that I decided to check out the tank one more time. When I lifted the bottle cover, I immediately smelled gas!
I turned off the tank, and checked the connections...all o.k. I turned on the tank, and listen to the unused hose....YEP, free flowing gas! Good thing we don't smoke! God smiles on idiots! But I'm very careful about gas...I just didn't think gas would flow out the other hose, and it was a soft enough flow that one wouldn't smell it at first.
So my question... is this normal? I had the selector to the full tank, but still the gas came out the hose. I thought that the hoses (as advertized by CW) had a "free flow" limiter? Moving the selector makes no difference....is the regulator bad (it's the orginal fisher)? I've heard horror stories about newer regulators...that's why I haven't upgraded.
