Am considering the value of replacing a welded copper riser with iron on my three-year old gas boiler. Is it too late, the damage done? Would the galvanic reaction of copper condensate on iron be causing the brown flecks I see in the sight glass? I keep the ph around 9.0 but this galvanic reaction thing bothers me. There's no loss of water through leaks where copper meets iron (yet).

    The big problem with copper supply pipes is the excessive expansion and contraction of the copper itself. This can put stress on the soldered joints, and cause them to fail.
    Post some pictures, so we can advise on the layout, when you recipe in iron pipe.--NBC
