Radiator valve bushed down?

I noticed a few of my smaller radiators have their inlet bushed down to what I think is 1" rather than 1 1/4".  Wouldn't this cause the radiator to hold more water rather then allow it all to drain out?



These radiators are around 26-28sqft of EDR.  I'm assuming even if this is technically wrong the fact its been this way for 80+ years means I don't want to mess with it.  But maybe it explains why I have issues with the Hoffman 1As collecting a drop of water in the orifice on these rads.

    Hi Gerry,



    Here you go, please ignore the 2x12 next to the radiator. I've been using it as a scaffold for painting. Its not a normal bedroom decoration :)

    Hi Gerry,



    Here you go. I would think this would cause water to lay in the radiator no matter how much pitch you put on it?

    We see this all the time

    and it works OK as long as the radiator isn't too big. Yours should be fine.

    All my upstairs radiators are like that.

    They range from 22–36 ft.² EDR.



    On the plus side, if you need to take out the radiator spud, you can usually get the bushing to come out.

    Waterfall

    I know the OP is satisfied with the answers already given, but I thought I'd share my experience.



    I have two radiators bushed down like that.  One, a fairly tall one, does make some noise.  It isn't banging or anything like that.  If you listen very carefully while it is filling with steam, it sounds like there is a miniature waterfall inside. Once the vent closes, it gets quiet again. The larger amount of condensate from steam hitting a cold radiator must be trickling into the little pool of water at the bottom. It's a pleasant sound, really . . . unless I need to use the bathroom.
