I decided to just get all new co2 side stuff (other than gas disconnects, which are easily disassembled and cleaned). Upgraded to a dual pressure gauge regulator. I may take this current one apart to see if it can be cleaned and rebuilt. Also got a new 4 way manifold, upgrade from a 3, so I can have a 4th keg carbonating. Figured, why the hell not. It's a little money I have to spend, plus I had a gift card for Northern Brewer anyway.
Be nice if I could get the other regulator functional again. We shall see.
Do you guys sanitize new co2 line?
Thanks for all your input, guys. I appreciate it.
