While a friend and I were talking about hard water and softeners it came up that he does not soften the watter to his toilet. He figures it is cheaper to replace the valve every year or so than it is to flush soft water down the drain. He has very hard water. Mine is at 26 grain and I think his is worse than that! I am installing a softener soon and I am wondering if there is any reason to do the same. One other difference is he has a cheep toilet and I plan on putting in one of the TOTO brand toilets.
