Great topic for a thread.

Years back we installed a water softener and a activated carbon filter to treat all the incoming city water to the house. Every tap in the house gets high quality drinking water without the chlorine. The softener is key too, it allows us to cut detergent use in half and that adds up when you do 15 loads of laundry a week like I do here. I think the whole thing was a couple grand. It has paid for itself at least a few times already.
