Reasons why steam boiler water level too high and

Jul 22, 2015 · Reasons: The steam boiler's water line is surging. Dirty water, a too-high pH, overfiring and improper near-boiler piping can all cause the steam boiler's water line to surge up and down. If there's an automatic water feeder on the boiler, it will open and close each time the water line rocks.
