Yay for TLA’s! Here’s an easy way to clean a keg-kettle. I bought one of these 360° sprinkler heads and a 6″ x 1/2″ PVC pipe nipple. I threaded that onto the sump pump from my Mark’s Keg Washer and dropped it into my keggle at the end of the brew day with 3 gallons of hot water I’d recovered from the chilling cycle. I adjusted the screw so that the spray hit right at the top of the dirt line, and used a low flame to keep the PBW solution right at 130-140°F while I was pitching yeast and cleaning up the mash tun. Worked like a charm!
