in THE MAIN WALL
Took this beast apart today (I've had worse ideas) to see if someone had removed the float mechanism. I saw the rubber gasket and had a suspicion however t was all intact and everything moved like it was brand new. Below are the pics

    The float looks nice..now ya gotta make sure the lower section where the float rides up and down is clean. That small subsection and its water level, looks crucial to its proper operation. Folks were wondering where the float got its water supply from.
    ...After that is done, the actual vent sealing ability... From the manual, it sounded like a metal to metal sealing surface lapped togeather.

    Remember that this device was there in the days of coal, so that if someone put an extra load of coal into the boiler, the ensuing rise in pressure would not flood the returns.
    Not much chance of that happening today, with a Vaporstat, and low pressure gauge! In addition, there may be the possibility of sub-atmospheric operation, AKA vacuum.--NBC
