In all Ultra and Evergreen boilers WM requires you test the water and treat it with Sentinel 100 water treatment. Does this apply to systems with glycol in them and is the test procedure the same? Thanks

    You should contact W-M. I just bought a bunch of X100 at supplyhouse.

    I just heard back from my rep and he says that virtually all glycol for heating systems already has treatment in it so I don't need to add any to it. That is not from WM officially though so I don't know if that would be the final word...
