    Thanks so much for the practical advice! It has been pretty hard for me to find.

    You left out the radiator valves... My system started losing water and it turned out to be a couple of valves that need to have the packing redone. A really simple thing to do, but it took me months to figure it out.

    Double-doped all iron near-boiler piping ..... "old school" works.

    Excellent article. Experienced nearly all of those issues. First a leaky return pipe, which didn’t solve the constantly evaporating water from the boiler. Turned out the boiler had a hole as described above. A new boiler along with replacing the radiator values has the system finally working properly and retaining the proper water levels.

    Don’t forget chloride issues. As Dan stated oxygen will create holes at the disengaging area, water line, but chloride erosion is at the top of the castings.
