I got a test kit at Home Depot. Once I got the results I bought my water softener and filter unit from the above place (Ohio Pure Water.com).

Before I bought it, I emailed and called them with several questions and called with questions after I installed it. They are very helpful and I recommend them.

P.S. They send your order to you UPS. I placed my order at 6 am on Monday morning and the UPS truck showed up at 2 pm on Tuesday. Top notch service! [img]/forums/images/icons/smirk.gif[/img]
