Let’s be honest: installing a water softener is not for everyone. If you can solder copper pipe, read a manual, and not cry when things leak, you can save $200–$500.
But if the thought of cutting into your main water line makes you sweat? Hire a pro. It’s $300–$1,000, but you’ll sleep better. No one wants a indoor pool in their basement.
Pro tip: Always get at least three quotes. And ask if the price includes the bypass valve—some sneaky installers charge extra for that little plastic knob.
