Disconnected steam radiators

[wot]

I have two steam radiators on third floor with gas boiler in basement. These two radiators are dead as a doornail and have tried all of the obvious fixes. I don't think they are connected somewhere. Is there a way of finding the disconnection point without ripping open walls and following piping?

Is it a one or two pipe stem system?

try and trace the piping, you may have a valve off in the boiler room.

could be water bound

That was my question. How does one go about doing that?

it sounds to me like maybe you should call a plumber, or hvac technician

I would be looking at the vent on the radiator.

What if the pipe leading into the floor is not hot either?

 

[wot]

Yes, that's true but I would like to do that properly informed rather than out of ignorance.

If the vent isn't working the seam can not move through the line. Post a picture of the type vent you have on that radiator. Depending on the type vent you have there are a couple of simple tests you can do to see if it's working.

Picture is posted in thread. Please note that no part of radiator is hot including the pipe going into the floor. I did remove the vent to replace with new one at some point.

The vent would be on the other side opposite from the valve and half way up on the radiator.

either you are air bound, crack open a union to check if you are.

or, a valve is off in your boiler room

check boiler room valves.
