steam question

Steamhead (in transit)

filled with water. It may be hidden in a wall or ceiling. Do whatever you must to unearth it.

Another possibility is that the rad shutoff valve has broken, and part of the valve is blocking the steam flow.

What is the EDR of the rad in question? If the horizontal runout is 25 feet and only 1 inch, it might be too small. Those long runouts require either larger pipe sizes or riser drips to the wet return to work well.

Check the pitch of the piping

my guess is there's a low point in the piping between the main and the rad, where water can collect and block the steam.

If this isn't the problem, check the pipe size against that of the other runouts. It might be too small.
