radiator issues

srock Member Posts: 1
i am working on a church and i have a two pipe steam system. I cannot get any heat to some of the radiator the main line is hot and some of the take off lines are hot. I can remove the valve and i get no steam at the radiator there is not even pressure there it is like the pipe is not even connected.all the traps have been rebuilt and the return line screens have been cleaned.any suggestions would be appreciated.

    The first thing that comes to mind

    is to check the pitch and routing of the runouts connected to the problem radiators.  If there is a way for condensate to get really trapped, you could wind up with no pressure and no steam.

    removing the valve, or disconnecting the union?
