we just bought our house (repo) and there was a no salt filtration on the well. This has not stopped the iron stains or the silt coming in. the water is so hard that even applying lotions and oils to ourselves three x's a day does not help. We can not even use the outside water faucets because the silt has cloged the valves so that if we open them we cannot shut them off. We have a filter along with the other system that we have to change every one and a half to two months, but it does not stop the silt coming in. is there help for both problems?
