I'm piecing my kegging kit together. I have three 1/6th bbl with sanke tops. I have two sanke taps with the pumps for party kegs. Obviously I don't want the hand pumps. One seems fine to replace the pump with a gas line, though I haven't figured out which beer nut I need yet. The second tap doesn't have a pressure release that I can see. I imagine the pressure release is necessary for safety but I'm not sure. I got a good deal on it all with a 25# steel Co2 tank but just want to make sure I don't do something stupid, it happens from time to time you know. Thanks.
