So, when testing water for a hydronic system, I need to test for Ph, hardness, and TDS?

    I just got the water some quality numbers from are town water department. To me, they look real good. Chloride 23ppm, pH 8, Chlorine .68 ppm, TDS 56-74, hardness 35.7 ppm-

    Does the town have just one water source? Is the test current?
    Test results can vary throughout the year and if they switch or blend sources

    It’s best to test at your home also. Those are good numbers when compared to most of the boiler installation manual fluid specs

    Yes, there are 6 wells, but all are treated in 1 location. Test is a few years old. Just thought this was an easy way to get an idea of wether or not I might have a problem.
