I'm planning to finally deal with the hard water in my home. Before I get a plumber involved, I wanted to check if I could DIY the installation, so here I am.
The water main pipes and valves are exterior to the home adjacent to the garage. After that, the only pipes on the outside of the walls are on the opposite side of the garage as seen in the picture below when entering/exiting the water heater.
Am I able to turn off the main, cut into the inlet seen in the picture, redirect that to a water softener next to the water heater, and then feed the outlet of the water softener back into the water heater? Or am I stuck having to cut through drywall at a closer point to the main?
I'm also not sure what to do about draining the water softener because there's nothing nearby that could take it. There's no floor drain or egress from the garage. The closest thing would probably be the laundry drain lines behind the drywall near the attached picture.
Is it common to have to dig through walls to plumb for a water softener?
