So I came across a guy giving away a keggerator with a tap, 5lb co2 tank, and the regulator. If this isn't the beer gods telling me it's time to start kegging I don't know what is. The entire set up had sat in his garage for about two years with beer in the lines so they're trashed, how do I best clean the tap? I'm thinking take it as apart as I can get it and soak it in bpw overnight. And on that note how apart should I be able to get it? I've taken the tap out of the tower and the handle out of the tap to the point where the o-rings come out as well and I can see the sliding mechanism inside.
The regulator is missing the clear face on the tank's gauge but seems to work alright. The co2 tank still has some pressure in it, just under 1000psi, and is within its hydrotest date. Is that enough to push star san through everything and for drinking or should I trade it in before hooking it up to the full keg? I'm sure I could take it off while the keg is carbed but I'm trying to keep this as simple as possible and also would like to minimize trips to the store.
Thanks all.
