in THE MAIN WALL
i have a steam system, when the boiler shuts off and the radiator cools slightly, the valve makes a loud sucking noise, like a vacuum...any idea to what the problem may be?

    Noisy vents

    Radiator vents expel air when heating and draw in air when the boiler turns off. Your vent sounds as though it's doing its job.



    You will get more attention if you re-post in the "Steam" forum.

    Loud sucking noise

    The main (not rad) vents should be doing the big job of air removal, and vacuum relief. Post some pictures, and we can advise what replacements or additions may be needed. Noisy vents indicate a lack of main venting capacity.--NBC
