We moved into our house about 10 months ago and apparently the area we live in has high iron. A year ago the people who lived here previously put in a new whole house system Aqua Treatment Service with a two tanks that filter in some way and a brine tank. I know very little about it but it is supposed to be able to handle at most 10ppm of iron. In december the iron levels were around 10ppm and the system seemed to be doing its job. Unfortunately a week ago after much rain and a weekend away our shower and toilets are stained brown and when tested the water pre and post filter is testing at 15ppm. We are now aware that this is extremely high and if we have to put in a new system we just want to make sure it is going to be adequate to handle the job. I think the water coming into the house is 7-8gpm but that is about all I know. Our water treatment person is trying to determine what will work but most likely recommending a water right product. Any advice would be much appreciated.
