Just a quick follow-up - this is probably still the most valuable piece of equipment in the brewery that I built. It saves a lot of time and more importantly it saves chemicals! One thing I did add is a tee right under the lid. The tee has a barb that I attached some PVC tubing to with a liquid ball lock connector. After I slide the keg down, I connect this to the out side. This way I blast PBW through the liquid dip tube the entire cycle and there is absolutely no need to break the keg down. I attached a bare gas ball lock connector to the gas side so that it allows PBW to pass through. Highly recommend this!
