I bought this water softener to go in my new home.  I have never had one or hooked one up before, honestly never even seen one before.  But talking to my neighbor s they all recommend this brand and told me it was easy to install.  So with the instructions and a quick video online, I was done in about 1-2 hours from start to finish.  That was to plum into the house if you're just replacing it an easy 30 min.
