I recently received a kegerator (an Edgestar KC1000 series), with a ball lock 5 gallon keg and a 5lb CO2 bottle. I was excited to start brewing with a keg, as I’ve been doing bottles now for a few years, so I brewed up a batch and then put the beer in the keg after secondary, following all the instructions and reading as much as I could online as well.
It was a disaster. I lost the batch entirely. The CO2 would leak out within a few hours, and I could never figure out where the problem was.
So, I resolved to try to solve this issue before putting more beer in there. My question is essentially this: is it a good idea to use water in the keg to try to isolate leaks and ensure a good, solid hookup? What I’d like to do is fill the keg with water, hook the CO2 to it, and then work on isolating any leaks, replacing hoses or o-rings or anything else. That way I don’t lose a batch of beer in the process.
If that doesn’t work, or isn’t recommended, is there another way?
