Jun 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. This type of problem is built into the boiler design, and it's tremendously
In Boiler Safety, Water Level Is Critical - EHS Daily Advisor
The height of the gauge glass water connection into the boiler. The TDS and chemical analysis of the boiler water. The size of the boiler shell. Level changes due to boiler circulation With a boiler on high load, the strong circulation of the boiler water will cause the water level to vary along the length of the boiler.

Surging Water Levels on a Boiler | eHow
If there isn't a mechanical problem, it sounds like the conductivity of your boiler water is too high. That can make the level in the sightglass/ level control assembly bob up and down. Call a couple of the local boiler companies and get a recommendation for a water treatment company.
Surging water levels in your boiler can be caused by numerous reasons but are usually a result of excess dirt or oil in the water. The condition is characterized by quickly changing water levels, which is generally due to inefficient steam release. Debris prevents steam from adequately escaping the water, causing it to rise and drop randomly.
