The first keg I ever bought was a sixtel off of a small brewery that was going out of business. This was an ill-advised purchase for a starting homebrewer, although some people swear by them since they were designed to hold and dispense beer. However they are notoriously difficult to clean and even harder to inspect. Later, I will post the ins and outs of the sixtel’s build.
I had some leaking issues after replacing the split ring that holds the spear. It’s important to verify that all the o-rings are in good condition before reassembling.
