Slide the flexible hoses onto the valve connections and tighten them with a wrench. Don’t go all hulk-mode here; hand-tight plus a quarter turn is the sweet spot. Then, connect the other ends to your cut pipe using push-fit fittings or solder joints, depending on your comfort level.
If you’re using push-fit, you just push—the name is not a lie. It’s the grown-up version of snapping LEGOs, and it feels extremely satisfying.
Step 4: The Drain Tube & Brine Tank
Your softener needs to flush out the yucky minerals from time to time. Attach a small drain tube from the softener to your floor drain or a nearby standpipe. This is the "sweat" of your system—healthy and necessary.
Next, add the brine tank (the one you’ll fill with salt tablets). Just plug it in next to the unit, connect the tube, and fill it with about three-quarters of a bag of salt. Don’t overfill—your future self will thank you.
