Single zone baseboard heat (cast iron) but one floor is not getting hot..

Hello all.
I have a split level home with 4 floors.
The top 2 floor baseboard get really hot but the bottom level does not.
The boiler is in the basement which is finished but it is hot for the heat thrown off the boiler. Yesterday I did some research one end of the baseboard has a nozzle so I screwed a hose on it and let out a lot of water and it got hot on that side of the cast iron baseboard but not the other. There was a bleed valve on the other end so I bled it until the water was hot and then the whole baseboard got really hot but did not stay hot. There is a valve under the bleeder that I turned but did not hear water going through so I think it may be broken.. Anything else I can try before I call someone to replace the valve.. This room that the baseboard is in is against the wall next to the garage so it was freezing on that level the last couple day here in nj..

Hi Stoned,

Sorry we seem to have missed your first post... happenz time to time.

Do you happen to know if your system is piped with what are called 'Monoflo(tm)' tee fittings?

These can be difficult to bleed air from...

I was going to say that you might possibly have a freeze up, but you said you were able to get the whole baseboard hot by bleeding it, so maybe not.

Can you take and post some pictures of your boiler system?

Also, look for where the pipes to the baseboard come off the main pipe and look carefully at those tee fittings. If there is an ARROW indicating flow, or possible a red ring, you may have monoflo...

Take a picture of the tee fittings too.

I'm sorry that rulz don't allow us to provide references ... not Angie's List...
