Welcome to our forum.
No, I don't think PH being in the 6.6 range for a week will eat a heater up.
I would agree, especially on a newer tub. 8-)
Are the pipes in your house copper and could your tap water Ph be low? Â do you ever see green in your sinks or bath tub around the drain? Â Acid water can eat the copper from the pipes. I wonder though if it would be enough to cause what you are experiencing. :-/
It was suggested to me that electrolosis (sp?) of the pipes can cause the pipes to errode too.
Hey Chad I just called Jacuzzi tech. And like I thought the element itself is stainless steel, he doubted there was any kind of copper in there at all as far as wiring holding the element in place. Â I really am starting to think its partly the nat 2 and something else causing it?? Â If your heater is falling apart from the inside, (first I would have ever seen from laing) it will start tripping the breaker pretty quick, I would think.
