I have one-pipe steam system. It seems that one of
the radiators got clogged and condensate water cannot
go back to the boiler. As a result, water fills the
air vent and prevents steam from entering.
I check everything else - pipe pitch, radiator pitch,
I changed an air valve - this seems to be the only reason.
How can you "un-clog" the radiator? Can I use "snake"
to do that?
