I hooked this setup together tonight, to test my magnetic pump.
I bought a few of these Junior kegs with D-type connector. Kettle's first use too.
Had to drain beer out of the kegs first, so I did it with the aftermarket D-connector with the one way valves removed, and emptied into a keggle, which I will the empty on the garden.
Mixed up about 60 litres of Coles generic percarbonate stain remover into the kettle and heated that while I drained 4 kegs and peeled off a load of stickers and sticky tape.
I connected the adaptor into the keg, and inverted it over the kettle on a couple of pieces of plastic square tube (to hold the keg above the kettle), and fired up the pump, and ran for 10 minutes per keg.
Photo 1 is an overview shot
Photo 2 shows the keg connector and the keg sitting on the square tube that was handy
Photo 3 is a side shot, with the tubing coming up from the pump, over the side of the kettle and up into the Beer Out connector
The hot percarbonate solution then pumps into the dip tube and up into the bottom of the keg across the bottom and down the sides of the keg and down out of the Gas In part of the connector.
The hot cleaning solution then returns to the kettle.
I hope a 10 minute cycle is enough for these kegs, as I do not know their history, but it looks like they made a few trips to a major commercial beer competition.
Will rinse with water and then recirculate some Brewsan sanitiser, which I would have done tonight, if I had enough time.
Will repeat with the other 4 Junior kegs and 3 30 litre kegs (2 X D type and 1 x A-type).
Hope this helps someone. Maybe I can post more photos when I finish the job.
