Bought home, need help with water softener
Hey guys, I'm a young and just bought my first home. It was foreclosed and was vacant for at least 6 months prior to my purchase. I know absolutely nothing about water softeners.
I have city water, but it is hard. The softener has been unplugged ever since I've seen it. I believe it is a Treck 2510?
There's a few gallons in the tank next to it, with some undissolved salt at the bottom it looks like. I also don't know what I should do about the settings. See Pictures.
What do I need to do to get this thing up and running properly?
