clogged low water cutoff valve
All winter I have been using the low water cutoff valve to "change the water" in my system (steam single pipe) and get rid of the built up sediment. I've been doing this every 2-4 weeks until lately i slipped to ~ 6weeks. When i went to let the wwater out last night only a few drops came out. I think my system still has water as indigated by the vertical glass water gauge. The gauge is 3/4 full and when i add more to the water system the water level in the gauge goes up.
it seems to me that the cutoff valve is glogged. Any ideas how to confirm this and to clear it up?
