How does it work?

Howard Emerson

Hi Brad,
Thanks for reply!

I left the valves in the 'in line' position, and we'll see what happens next time she turns the heat on.

In the meantime, though, I think the thermostatic valves are a great idea, but that's out of my realm, especially since it's my M-I-L...........How much trouble could a guy get into?

Now I did replace a baseboard auto-bleeder on my system with some tips from Bob O'Brien, but this is at least a couple of hundred pounds, besides being filled with water

In fact here's a pic of my new bathroom (remember the thread where I was in sticker shock for plumbing prices, etc?) and a pic of the radiator cover (with shorter bleeder) I made of cherry, cherry veneer and plastic grommet vent.

Thanks again!

Cast iron radiators at my M-I-L's house

Hi all,
The valves on these CI radiators (hot water)seem to just keep turning. Are they 'on' if the 'lines'on the knob are parallel with the pipe, and 'off' if they're perpendicular?

I believe they're on a copper monoflow system because I can feel heat below the valves, but none rises. I did bleed a drop of air.

Thanks for any insight.

Regards,
Howard

Could be

sheared off. Many HW valves were 1/4 turn types with a flat plate or rotating plug with orifice. Others are the rising stem type which seats over an opening.

If it keeps turning with no effect, the stem could be sheared off internally. Time to replace. If you DO wind up replacing the entire valve, there are thermostatic radiator valves which often match the centerline dimensions. Control and isolation in one. A good thing.
