Hi. Two months ago I lost a full home brew keg due to a leaky faucet. Today about 1/4 keg of home brew leaked out from a different faucet. Each time was from a slow drip, so when we thought it wasn't dripping and walked away, it was actually dripping. The faucets are Perlick, the model is the kind with the "push back" feature for foam. Here's my cleaning routine: I was told to run cleanser (PBW, B-brite, etc) through them for a minute when I change the keg. I think I've taken them apart once since I got them 2 yrs ago. After I run cleanser, I follow it with clean water (or beer). I just did this not even 2 months ago and they're dripping again. Any thoughts? They're expensive and I don't want to replace them. I'm guessing I need to modify my cleaning routine. Or, are there gaskets in there that wear out? I'd appreciate thoughts or suggestions. Thanks.
