Low Water in Boiler - Wet Steam Likely — Heating

The reduction in volume of changing steam to water is a reduction in volume of 1700. The rapid drop in pressure from a positive steam pressure to a vacuum causes some of the water in the boiler to instantly change to steam as the pressure drops and this steam quickly causes water in the boiler to evaporate lowering the water level.
