Hi All: I have an old heating system. It is a Forced Hot Water System
with those old cast iron (about 30" tall) under every window. They are
not recessed in the wall. Each of the upstairs radiators has a shutoff
valve. It is my understanding that the valves only partially shut off
the radaitor. Lately I notice that the tmeperature upstairs gets
really hot and downstairs is cool. I tried shutting these valvles and
most are hard to turn and I'm afraid I wil brake one or cause leakage.
Anyone have any experience with these radiator valvles? The last thing
I need now is to break one of these in the middle of the winter.
