Flushing a Steam One Pipe System

I posted last week asking for suggestions on a water hammer issue that has just started on a property I bought 3 months ago. It is a one pipe steam system that my plumber put a auto water feed on, that is at times overfilling the boiler. I also learned the previous owner overfilled the sytem last year enough that the radiators overfilled on 2nd floor. One of the suggestions the wall had was to flush the system to get rid of any gump or anything that might block the steam causing water hammer. When I spoke with my plumber yesterday he said you cant flush a one pipe steam system and essentially that was done when they emptied the boiler to put the auto feed on. Am I missing something here. Any thoughts or suggestions would be appreciatted.

    Paul, I can give you the basics for water hammer. look for places that water can pool in a pipe that has steam. broken hangers that let pipes hang/ sag. you should be able to locate where the water hammer is coming from. If you can take a picture of the piping at the location
