In the event you are unable to serve draught beer for an extended period, it is important to take some steps to make sure your system stays healthy and you are not faced with an unexpected expense or quality concerns when starting it back up. If beer is left stagnant in draught lines for too long, the system will be at risk of an irreversible bacterial contamination. Taking the right steps can prevent you from having to deal with dangerous gas leak hazards, costly draught line contamination, or even more expensive draught line replacement.
