I have a kegco co2 regulator purchased in Nov 2015 that i use to carbonate kegs and bottle with a beergun. Today was pretty challenging. I released the pressure on the keg and tried to reduce the pressure at the regulator. I could bring it down to 10 psi but any lower resulted in no co2 pressure at the beer gun. A slight, like less than 15 degree turn of the regulator put it back at 10 psi. It will go higher than that but not lower. Surely a regulator less than two years old isn’t shot. My oxy-acetylene regulators are older than I am and theyre still going strong.
Nothing is built the way it used to be anymore. The ones on your welding rig are probably still working because they’re older than you are. They likely cost more than the CO2 one also.
You may need to disassemble and clean/lube the CO2 regulator. I’ve never taken one apart but the rebuild kits don’t look like they have too many parts in them. So take my comments for what they’re worth.
I don’t think it’s leaking- I use it to carb kegs. It was hooked up for at least two weeks without me checking it before yesterday. I would have thought a leak would have emptied that 5 pound cylinder.
Figured I didn’t have much to lose so I disassembled the regulator. The diaphragm had some small debris on it so I wiped it clean and reassembled it. Seems to work now.
