I know that some water heater manufacturers blame their tank failures on water softeners but… they never show the chemistry to back up their claims.
They also tout their glass lining. Glass is impervious to anything found in water, so howzit that water with the hardness removed and a bit of sodium added (about 7.85 mg/l per grain per gallon softened), causes their glass lined tanks to rust out?
So if anyone knows the chemistry of the claim, I’d like to see it. For all the millions of softeners in use in both residential and commercial establishments, it certainly would be announced to everyone if those softeners were responsible for ruining water heaters. And if the glass lining remained intact, you could fill the heater with acid or alkaline and it wouldn’t rust out; anode rod or not.
