Steam Boiler Fill Level Problem. He also bragged about fixing some lady's boiler with a switch or something and charged her $10,000 (ten thousand dollars). He took our $125 for his time and left without fixing anything, not even making any concrete recommendations, except that he could replace the copper headers with iron pipe for $3,400.
Automatic water feeder valves on steam boilers. A steam boiler will be damaged or unsafe if its water level falls too low. The water feed valve on a steam boiler has to operate more often, and will be a more heavy-duty (and probably reliable) device than that used on hot water heating system boilers.
Jun 24, 2014 · The boiler has very narrow sections. When the steam bubbles condense, the water in the boiler will fall to a point lower than the water in the gauge glass. The water in the gauge glass offsets this by falling into the boiler. If you have an automatic water feeder, it will open and eventually flood the boiler.
