Yet another keg cleaner:




Sorry I don't have it documented but I will. It's based on Doc's design but with more PVC than copper and has a platform for the keg to sit on. The pump is the Little Giant 1/6 hp 5MSP. Best prices are on ebay. The basic construction is a riser built out of PVC fittings coming off the pump output. A platform made from a cutting board sits on top of the riser in the front and on two nylon spacers in the back (the handle is removed and the screws are reused.)
PBW is circulated through the center main spray pipe and both the beer-out and the gas-in posts and dip tubes. The whole thing sits in a 4 gallon bucket with 1 gallon of hot PBW. It also cleans brew pots, carboys, chest freezers, beer lines, and glass cylindrical smoking devices (so I'm told

).
Tasty
