Step 7 · Reconnect Faucet Supply Line

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Align the faucet supply line with the outlet on the new angle stop. Thread the supply line's compression nut onto the valve's outlet by hand. Make sure it threads on smoothly to avoid cross-threading. Once it is hand-tight, use an adjustable wrench to give it another quarter to half-turn to snug it up. This connection does not need extreme force; the rubber cone seal inside the supply line nut creates the seal.
