to my steam boiler stayed on last night to the point it filled the boiler past the sight tube. I turned it off because I heard it running too long. Took the excess water off by means of the skimmer valve and the lower boiler drain valve. The boiler is a Weil-McLain about 10 years old with a low water cut-off and auto fill control. Is there some preventive service I should be doing for this water set-up? I currently skim and drain the boiler once a month to check the low water cut-off operation but how do you check the fill? Thanks Herb
