Wondering if anyone is using or familiar with a Global Stainless single head manual keg washer. I’ve purchased one used and I can’t find any literature on it. Control panel and pump both work but it’s missing a couple of small pieces in terms of plumbing/hoses. Just a diagram or photo of one set up properly would work. I called Global Stainless, they seem hesitant to provide any information. Liability maybe, not sure.
