You’ve got a spot. You’ve got a bypass valve. Now it’s time to cut into your main water line. Measure twice, cut once—unless you enjoy buying more pipe from the hardware store.
Use your pipe cutter to make a clean cut. Then attach two compression fittings or sweat copper fittings (soldering is for brave souls). Thread the flexible hoses from the fittings to your bypass valve.

Tighten everything with a wrench, but don’t Hulk-smash it. Overtightening can crack brass fittings, and then you’ll be crying into your bucket. Hand-tight plus a quarter turn is the sweet spot.
Don’t Forget the Drain Line
Connect a small, clear plastic tube from the softener’s “drain” port to the bucket or drain. This carries away the salty brine during regeneration. If the tube kinks, your basement will become a saline wading pool.
Secure the tube with a zip tie so it doesn’t flop out like a sick garden hose. A loose drain line is the leading cause of “why is my floor wet?” panic attacks.
