There does not appear to be a clog behind that bleeder.

Do you mean right behind the bleeder? Any clog would likely be farther
down.


Hot water radiators get filled with house water pressure.

Tnat's what I thought. That bleeding is done when the furnace is off
implies there is enough water pressure to fill all the radiators.

Does the home have adequate water pressure at the second floor sinks,
etc?

Are these new radiators or used. Perhaps a thermometer, espeically a
one of those which measures from a distance, or even a bulb thermometer,
could be placed along the ribs of the radiator, moved up and down to
find how high the water goes, and maybe there's a blockage.

Hit it with a mallet or the side of a hammer a few times to dislodge the
scale in an old radiator????


You bleed it when there is
pressure to it. Make sure the fill valve is open before you bleed it.

Make sure the fill valve is open.
