Conical 1/4M (metric) brass anti-syphon valve for your commercial or prosumer heat exchanger espresso machine. Part #EP50290Also known as a vacuum breaker valve, this important little device equalizes the air pressure in your boiler as it cools down and the pressure reverts to 1 BAR (atmosphere). This prevents the possibility of milk being sucked into the boiler inadvertently through the milk wands/valves. This happens more often than you think and results in costly boiler cleaning to remove the scorched milk smell.Technicians Tip: Push in once a month, to ensure it does not stick in the closed position. This is important in cases where the machine is always left on in commercial environments. If steam is escaping after the initial heat-up phase, the internal seal is worn. If water pours from this valve, the boiler is overfilling--likely due to a tarnished/dirty boiler water level probe or too much water line pressure (if the machine is plumbed-in).Metric "1/4" size actually measures about 1/2 inch across.
