    8 way boiler treatment

    My oil man is complaining that my addition of Stewart Hall's *8 Way boiler treatment in my steam boiler made the low water cut off die prematurely. He said the copper insides was "eaten up" by it. (it was two years old) of course just beyond the warrenty.
    I have used this on all my steam boilers (9 of them) and I can't imagine that this could eat up copper. I once had the MSDS (can't find it now) a few years ago and thought it was pretty benign. Mostly something to keep the PH up w/o problems. Anyone find that this additive has given them problems? It seems oil guys around here don't like ANY additives in steam boilers. I thought with all the o2 reaction It should,...

    shaky on chemistry

    Charles and others, I'm shaky on the chemistry, but do you think in normal amounts this can attack copper? I though low PH does. Not sure about sodium nitrate,...

    8-Way

    I have NEVER heard of such a problem with this product. This is all I've been using as a final water treatment.

    Furthermore, it cleans the entire system and has always prevented the kind of problems you mention.

    But there are two things to remember about using this stuff. If the system is contaminated, establishing a water treatment plan with the 8-way is initially problematic. Oils and other impurities will find their way to the surface of the boiler water, causing all kinds of trouble. You have to runs the system, skim, run the system, skim etc until all is OK. Then you're home free. It is amazing how many system balance problems are due to low quality steam. The 8-way (and similar) seem to perform a miracle, but its just science.

    Speaking of which, lets get to chemistry. I have heard that it is possible that any water treatment that contains any sodium hydroxide (lye) can react with heavy boiler scale and cause the pH to rise beyond 12.5, creating the risk of caustic attack. This is why I always clean the boiler first with an acid descaler, and thoroughly flush the boiler and near boiler piping of any acid or residue (I fill it to the top and into the near boiler piping with fresh rinse water). When your litmus paper shows a neutral condition, then institute the 8-Way water treatment. The elimination of scale will prevent the potential of caustic attack.

    Anything that can measure the actual pH is a plus so that you can see of the pH is getting too high.
