They do discourage us from using flex lines around here.
I’m wondering if I drain the heaters to just below the level of the pressure relief valves, then remove the valves, and use a funnel and a flex hose to pour in the peroxide. That way, I don’t have to unsolder anything.
My other question is, should I be completely draining the tanks, then adding in the peroxide, or just pour it in with whatever water is in each tank?
Do I leave the peroxide in for a set period of time before using the hot water, or should I be flushing the lines right away?
The two anodes I bought from you were “solid combo aluminum/zinc anode rod kit” . . . . . shipped to Schwenksville, PA.
