I found a corny keg that I was going to use a primary. The fittings that I found to fit has a relief valve that lifts a 1psi with a hose attached that runs into a sanitary solution. Does anyone see any problem using this as a primary. I guess it will always have positive pressure unless its greater than one pound. I dont think it will be a problem reaching 1psi as long as the brew is fermenting well. Anyone see any problems with this?
