I’m trying to figure out if I have a small co2 leak. I kegged my beer and stuck it in the fridge with the gas on 20psi to cold crash and start carbing. The next morning, I stuck my head in the fridge to check the gauge and felt lightheaded. I turned off the gas (valve at the tank closed, regulator open). Came back 8 hours later and the tank gauge showed zero (no surprise) and the keg pressure gauge showed 15psi. After 36 hours with the gas off, the keg pressure dropped to 5 psi. Last night, I turned the gas on, sprayed everything with soap or starsan (no bubbles), then closed both the tank valve and the regulator valve. It held 600psi overnight, so I guess I’ve ruled out leaks in the high-pressure side.
So, either I have a slow leak on the low pressure side, or I don’t have a leak and the lightheadedness wasn’t from co2. Any good way to figure this out, since I’m not getting any bubbles when I spray everything down?
I assume the drop from 20 psi to 5psi with the gas shut off for 36 hours was just the co2 being forced into the beer. I have 2.5 gallons of beer in a 3 gallon keg, so not too much headspace.
