Read MoreJun 25, 2014 · When the steam bubbles condense, the water in the boiler falls to a point lower than the water in the gauge glass. The water in the gauge glass offsets this by falling into the boiler. This usually turns on the low-water cutoff or the automatic water feeder. You wind up with nagging water level problems in the boiler.
