Replace Vacuum Breaker, V3

What is a Vacuum Breaker?
A vacuum breaker is a valve on the steam tank which seals after enough pressure has built up. As the name describes, the vacuum breaker creates a vacuum once sealed to prevent any back flow from steam steam wand when going from 'on' to 'off'. The valve has a gasket inside which, overtime, will wear out. This part is a preventative maintenance part which we recommend evaluating every 6-9 months and replacing every year.
