We just finished building our new house and moved in. I need to get a water softener. I'm on city water and the water quality is 17 GPG, iron is at 0.1 ppm, Calcium 210 ppm, Magnesium 210 ppm and Manganese is 0.056 ppm.

After reading through these forums and doing some research I think I'm going to go with the Fleck 7000SXT. It's just me, my wife, and 2 kids in the house so would 48k be a good size?

I installed a water heater at my last house with copper piping so I'm hoping I have the skills to install this myself as well. However, the new house is all PEX piping, which I've never done. I saw a section of 1" PEX that the plumbers labeled "Water Softener Rough In" so I believe I just need to cut into that, add an elbow fitting to each end, and run 1" pex from the fittings to the water softener. Does all that sound correct?
