I have been sidetracked with a bunch of other stuff so I haven't progressed any more on this. I have a couple other questions, if you don't mind. I don't have a drain anywhere near my water main/pressure tank. The drain I would probably tie into is about 35' away. Can I just run pex to tie into that?

The other question I have is I have limited space where this is going. It looks like the Kenmore softeners just take up less space in general. I am thinking of getting the AN online and then just getting a softener from Sears. Are the softeners from Sears any good? I have a brother that uses one and he seems pretty happy with it, although he as had it less than 6 months.
