FINAL GRAVITY PODCAST

Typically I'm pretty OCD about cleaning my kegerator lines/taps/faucets.  I will fill a keg with 2 gallons of hot Oxiclean (a Base) and flush the lines, after which I'll fill the lines with a StarSan solution (an Acid) and flush again using that same keg.  This Base/Acid rinse helps to break down the beerstone that can collect in your lines causing turbulence, foaming and off-flavors. 

I thought to myself that there had to be a better way, so I let that roll through my brain for a few days.  Then I realized that I had an unused pond/aquarium pump at home (Eheim 1250, 317gph).  This coupled with some 1/2" silicone tubing and an extra Sanke keg spear (yes, I keg in Sanke kegs) from cutting a keggle could do the trick nicely!  For those that use Corny kegs I'm sure you could do the same with a ball/pin lock liquid post and the appropriate adapter. 

I cut most of the diptube on the Sanke spear off using a pipe cutter leaving only about 1" to slide the silicone tubing over.  Then I attached the other end of the tubing to the output of the pump and dropped the whole thing in to a 5 gallon bucket filled with water for testing.  With a length of tubing slid over one of the faucets on my kegerator and run back in to the bucket, and the keg coupler attached I turned on the pump and began to recirculate the water through the lines.

First run, it works!
