Question Bleeding Ratiator question

I just turned our boiler on
and went ahead and bleeded the ratiators to make sure everything was good, well on the first floor all of the ratiators after air comes out water comes out, on the second floor even though radiator are warm no water comes out just air, is there anything I need to do??

Lizzy, check the pressure gauge on the boiler and tell us what it says...

The air you hear on the second floor coming OUT, might actually be going IN !

On the top is 15
on the bottom 180

If you think I have to add water to it can you let me know where?

By this photo?

15 psi sounds OK for a 2-storey house. You need to keep bleeding the upstairs radiators until water comes out.

In your photo, see the red automatic fill valve? Make sure the two blue-handled valves, one directly above the fill valve and one directly below, are wide open. The blue-handled bypass valve to the left of the red fill valve should be fully shut.

At 180 though, I might expect a bit higher... I'm curious what the pressure is when cold. It's still possible that your expansion tank needs checking/servicing. It's the most neglected part of a heating system.

If the air IS coming OUT, you should be able to blow bubbles with a little dish soap on the nozzle...

Lizzy, are those pics _your_ system? or another one _like_ yours... I think I've seen them before?

I guess they are yours! seems you are still adding pics... and a pink background!

I do wish I hadn't seen all that loose flaking A$B3$70$ on those pipes near the ceiling though.

wow! you have really good memory, you helped me 2 years ago with an issue with the same boiler, those pic were taking 2 yrs ago when I just moved to the house those flaking things arent there thank God! even though they arent there I still use my mask down there.

Any way NJ Trooper do u think I should have my furnace check out maybe a tune up to make sure everything is good? I have a service plan with SJ Gas so they should be able to do it.

I guess that's up to you really... you are paying for the service plan, right? so why not use it?

See that red bell shaped thing with the screw on top? That's your PRESSURE REDUCING VALVE. That's what sets the pressure in the boiler when the boiler is cold. You should have 12-15 PSI in the boiler to start with.

What is the pressure when the boiler is COLD?

On the pipes above and below that Reducing Valve are two blue handle valves. They should both be open if all is right with the world. One or both MIGHT be closed... if for example there is a problem with the reducing valve leaking through. But check and see if one or both are closed. If they are open, and the pressure IS low, the PRV could be plugged.

The blue valve to the left of the PRV is a FAST FILL BYPASS. You may have to open that one, but don't do it yet. First let us know what the pressure is COLD.

Or take advantage of the plan you are paying for... don't let them 'upsell' you though... they are fast talkers, and some work on commission!

jcasman, I barely have time to answer the posts on the forum, so your best bet is to ask yer questions here! sorry bout dat cap'n...
