    Check temperature differential between inlet and outlet. It can be tricky at different points during the heating cycle but there should generally be a 10° difference.
    I use a sonic measuring tool that listens to the trap opening and closing. Or not.

    The cheapest ($350) FLIR gun has been my best tool for this.
    Especially if you can follow the return pipe for a foot or 2 away from the trap.
    BTW, this is for rad traps not F&T.

    Has anyone tried the doctor stethoscope on the traps for the sound?

    A mechanic's stethoscope seems to work as well as the super expensive ultrasonic sensor that I've read are used industrially.
