OK, so I am at a bit of a standstill as my CO2 tank is empty and I want to take a trip to a LHBS in Berkeley, about a 45 min ride, and will not have time to do it until next weekend at best. So, in my boredom I decided to take apart my tap setup on my kegerator. The line is discolored but does not appear to be bad. So I thought why not ask the experts. I go thru a cleaning and sanitizing every keg change where I run cleaner thru the line and faucet at least twice, so 4 to 5 gallons worth twice, and then rinse with clean water twice to three times. I then mix up 4 gallons of Starsan and run that thru the system at least twice. I have had the same beer line in for probably about 3 years with no issues that I can tell. This kegerator may be going into retirement as I bought a nice, new to me, Komos two tap setup that will move into the spot once I get all the lines set up and the gas distribution worked out. So, my question to the masses, would it be wise to put a new tube on the old kegerator now? I have everything apart to really get into a good cleaning once I get my tank filled again so it is not a big deal either way. As always, any input is welcomed and appreciated.
