What is a Pressure Relief Valve? (with pictures) - wiseGEEK
The purpose of the vacuum breaker valve is to release the vacuum pressure in the espresso machine boiler. Specifically when it cools from a very hot state to room temperature. Without this part, the boiler will create a false vacuum pressure. As a result, the pressure regulator will read this as true pressure and not allow the unit to fully heat.
