since you are new to wells & softeners, there's a company called Springsoft near you that I've worked with and they were very good. if you need local help.
a bit off topic - is that a basement watchdog sump pump system? are you new to those? I've had very bad experience with those things. get yourself a 100A battery load tester from Harbor Freight
https://www.harborfreight.com/100a-612v-battery-load-tester-61747.html and test that battery every week, and before storms. check the electrolyte levels in a 6 cells every month don't trust the probe/alarm. this in addition to manually testing the pump to ensure it still runs and pumps. those 12V battery back up sump systems are notorious for failing at the very time you need them to work. I got rid of mine years ago and use inverters to power the redundant 120Vac primary pumps.
Edit. here's a pic of my sump power supplies. It's a bit messy, but very effective. 2 independent systems, each with a bank of deep cycle marine batteries, charger, auto transfer switch, and DC/AC inverter. and Storm Pro pumps in the pit. I built the ATSs myself (could not find anything like it for purchase). yes I know they have inverters with the charger and ATS built in, and I do have one, but they do not work how I want them to.
