Pick a spot near your main water shutoff valve. Ideally, it should be somewhere dry (like a garage or basement), with an electrical outlet nearby and a floor drain. Do not install it in a closet where you store holiday decorations—you’ll hate hauling salt bags past your antique Nutcracker collection.
Now, here’s the funny part: you also need to bypass the outdoor faucets. Why? Because watering your lawn with soft water is like giving your grass a salt lick. A quick way to do this is to tap into the line before the softener. Gary forgot this step, and his tomatoes looked depressed for a month.

The Actual Plumbing (No, You Won’t Flood Your House)
First, shut off the main water valve. I’m talking fully off—not the “drippy off” you do for a leaky faucet. Then, drain the pipes by opening the lowest faucet in the house (usually a basement sink or hose bib). If you skip this, you’ll get a face full of rusty water. Ask me how I know.
Cut the main line where you want the softener to sit. Leave yourself about 12 inches of working space—claustrophobic cuts are the enemy. Install a bypass valve first (the little white or blue plastic thing that lets you isolate the unit for maintenance). Trust me, when you’re changing the resin in ten years, you’ll kiss that valve.
Connect the inlet (from the street) to the “IN” port on the softener, and the outlet (to the house) to the “OUT” port. If you mix them up, the unit may still sort-of work, but it’ll regenerate like a confused teenager. Use PEX, copper, or flexible hoses—whatever your local code says (and yes, check the code; your water heater doesn’t want surprises).
The Drain Line: Your New Best Friend
Every softener needs a drain for its salty backflush. Run ½-inch tubing from the spigot on the control head to a floor drain, a washing machine standpipe, or a utility sink. Air gap is key here—don’t shove the hose into the drain; leave a gap. Otherwise, sewage could back up into your nice new machine, and nobody wants that flavor of irony.

Also, for the brine tank (where the salt goes), you’ll run a smaller tube from the unit to the tank. It’s usually a simple push-fit connection. If you screw it up, the salt won’t dissolve, and your water will stay hard. Hard water means crunchy hair. You want soft, silky hair, right? Right.
