First things first, are there any party pumps that have the pump attached to the side, and the beer spout coming out the top? Or did I end up with a tap coupler that's had the CO2 inlet converted for use with an air pump?
It's a Perlick unit, and currently has what seems like these two parts:
So if it was indeed originally a regular CO2 tap coupler, or even if not, would I be able to get this adapter, http://www.beveragefactory.com/draftbeer/pumps/replacement/HP-111.shtml ?
I know the description says it's for use the other way around, but since it seems that the threading is the same on both sides for the FN-013 long adapter that I seem to have currently, I'm imagining it should work?
Also, what's the going rate for CO2 from a local supplier? I'm imagining Airgas, etc, would be where I'd want to go? Tank rental/pricing, and then further refills/exchanges?
