Reasons why the condensate- or boiler-feed pump is
Jun 25, 2014 · The boiler's water line is priming or surging. Dirt is usually the culprit here. When you see droplets of water in the part of the gauge glass above the water line, it's time to clean the boiler. If the boiler is priming and surging, it can turn the pump controller on and off. That will make the boiler-feed pump add water when it shouldn't.
