in THE MAIN WALL

I have a 100 year old heating system. I would like to add some Corrosion Inhibitor preferably without having to drain down the whole system. I am somewhat stumped on how to do this.

    Do you gave a boiler drain, or any valve with a hose connection? Screw this on, open the valve wide open, pull the trigger. Takes seconds for it to inject in
