I brewed a zombie dust clone and kegged it. I put co2 on it and left it for 1 week, went today to pour a pint and nothing came out, pulled the pressure relief valve and there was no pressure in it. So i'm guessing i have a leak somewhere. what does that mean for my beer?
A more accurate title would be definite leak. The only change in your beer is it has aged an extra week.
So with the keg full of beer, how do I find the leak? I have used this keg one time with no issues, should I just take off the gas and liquid posts and tighten them back up?
First make sure there is gas in the tank (it happens). With a good tank, disconnect your gas coupler from the beer and crank the pressure up to 40+psi. If you don't "hear" the leak then spray all the connections with a starsan or soapy solution and look for bubbles. This will test everything except the coupler/tank connection. If you find a leak, don't assume it's the only one . . . check all your connections. Once sure you have everything checked, hook up the gas to the beer at normal pressure (or slightly higher). Assuming you're using cornys, test the base of the post, the poppet openings, and lid with the starsan solution. The final exam is to shut off the tank master valve and see if the system holds pressure for 24+ hours. Try this first when disconnected from the keg (or your flat beer will absorb the gas, showing a press drop). No matter what, don't walk off and leave the tank master valve open until you know all leaks have been corrected. Always remember to burp if you open the keg . . . if no long term exposure to air, the beer shouldn't suffer.
