Reply to comment by PuzzleheadedWalrus71 in Your annual reminder that if your apartment has a radiator, don't open and close the valve. This can create condensation in the system causing a knocking sound. Radiators are designed to be used with a series of open windows to balance heat. by emeyer94

You can ask your super to install an air release plug or smaller orifice. Opening the window is not ideal since all the humidity will escape and dry you out.
