    hmm, that turned out huge.

    also piping at the boiler not arranged to encourage the air to go to the tank.

    After you make that expensive repair and you still have the same problem, What will you check next?

    If it has a sight glass, the top valve packing may not be air tight. Dried up from no water contact.

    Will leak air but not water.

    Took me several years to figure that out and not lost the air cushion for maybe 7 years now.

    Wow can't put anything past you guys. Hope you enjoy the video. I hate when this happens on a job as it takes so long to discover what you did worked.

    What is even more fun is finding your compression tank and heating system with 13HG on the vacuum guage and figuring out why that happened.

    Hello Ray,

    After starting the circulator and the system sounding like it was pulling water and screaming through a clay straw while clawing the inside of the straw with fingernails, what I found was loose packing nuts on the gauge glass of the steel compression tank, 1/4 turn on each packing gland nut and to date in 7 years I have had no issues.

    I emptied the coal hopper on Wednesday as the young fellow that comes to clean and tune the coal stoker was coming as I cannot do it anymore due to the pacemaker in my chest as I have to avoid reaching and over exertion as it could loosen the pacemaker leads.

    I started the coal stoker and circulator to empty the remainder of coal in the throat of the hopper and there was no noise AKA screeching or bubbles migrating through the boiler for the 2 hours I ran the stoker to empty it more.
