Hello, I am new to the forum. Regarding a modern Weil Mclean steam boiler with auto fill valve and low water cutoff, I am not real sure how this is supposed to work exactly. For example, with the water level normal (just under half) I start to empty water into a bucket (to clear it out) at what point is the auto fill valve supposed to kick on a return the water to level? Is it when one gallon is removed, two gallons, etc? If I remove too much too fast, is the low water cutoff signaled first before the auto fill valve? Do the two systems work together and "talk to each other" Or are they completely independent? Also, at what point during the water removal does the low water cutoff kick on? Is it when the level in the sight glass goes to the very bottom of the glass? When the water disappears from the sight glass, does that mean that the boiler is empty or is it like a gas tank where even though you are on 'E' there is still 3-4 gallons left in the tank? Appreciate all your feedback, Aristotle
