Is the radiator valve (not vent) opened fully?

Has the disk fallen off the valve stem?

    if you can, turn the tstat up and see where the heat stops, bear in mind it may get real hot, you may have dirt/mud plugging a line, it may have bad pitch and a trap full of water from it, it may not even be connected, I've seen it.
  • Check the pitch of the piping

    between the main and the radiator. Bet you find a water pocket there.

    assuming

    you can get at both ends of any horizontal runs, the easiest way is to take a string (really!) and, with the aid of a helper or two, hold it tight against the fittings at both ends -- all the way at the ends. It should be the same distance from the pipe all the way along (a fancy way of saying the pipe should be straight!). Then you need to check that all 'horizontal' runs actually go slightly uphill towards the radiator -- use a really good level for this.

    Don't depend on sighting along the pipe. Ain't good enough.

    OK

    So you physically see that the valve disk is not sitting on the seat?

    You can stick your finger in the valve past it, and down into the pipe?

    Sorry

    Sorry, all I could think about here is my Dad's voice saying "That hurt like heck, didn't it?"

    Don't do this with the system full of steam....

    what should the pressure be for a one pipe system
  • Pressure

    Very low. like 2psi or lower. Where is this radiator in the system? Is it toward the end of the main line? In other words, far away from the boiler in pipe distance? This may be a venting issue. Steam systems must vent all of the AIR out of the line before the STEAM can get in. These are totaly different gasses and they do not mix. The air vents should be at the radiators to vent the air in the radiator out. The main pipes have big vents in the basement to let the air out of them also. It sounds like your system cycles off before your radiator gets steam. The result of not enough main venting. Check the main vents and post a picture of what you have.
