Stains in Toilet Bowls
My wife and I moved into a new house 4 months ago, and are having problems with stains in the toilet bowls and in the tubs. The water is clear and we start noticing the stains after about 5 days, the stains are a brownish color. The house has a sediment filter that I have to change after about 1 month due to pressure drop. I had a Culligan dealer come (unfortunately only my wife was present for the test) and he gave her the following results:
8 gpg hardness
trace of iron
He is suggesting that we install a "Big Blue" filter to see if that solves the staining issue. He said if that doesn't work that we should consider a refurbished super 5. Looking for any advice. Thanks.
