Vacuum conditions can quickly develop in brewing vessels, and the result of these conditions is all too frequently expensive damage to equipment. Often times the damaged equipment reduces plant capacity, is difficult or impossible to repair, and is stressful to the brewers involved in the failure. The good news is that vacuum failures are avoidable. In this presentation some of the most common causes of vacuum failure, how vacuum failures can be prevented, and some practical considerations related to the maintenance of vacuum relief valves will be reviewed.
