I live in Madison and my hard water has already claimed 2 shower temp cartridges, my fridge filtered water system and i should really just replace my shower door at this point. I think it's time for a whole-home water softener. I know nothing about the topic and i'm not much a DIYer so that's probably out of the question. What do i need to know, how much will it set me back and can someone recommend an installer? thanks in advance
