Occasional water coming out of main steam vents, what does this mean?

Hi,
I have a couple of the B&J Big Mouth vents. These vents are installed as part of my main vent assembly.

I have noticed that a perhaps 1/4 to 1/2 gallon of water escapes from these vents. My first guess would be that there is too much water in the boiler. However, if anything, the sight glass shows the water level to be a tad bit on the low side when this occurs.

Any ideas?

thanks.

Sounds like wet steam. Have you flushed or skimmed the boiler recently? How does the water line look? Does it bob up and down a lot or is it steady? How's the near boiler piping?

That volume of water shouldn't really be in that location. It could be a boiler piping issue, pitch issue, vents too close to the main and need elevated. It's not really a vent issue.
