Step 7 · Reconnect the Faucet Supply Line
Align the flexible faucet supply line with the outlet on the new angle stop. Screw the supply line's compression nut onto the valve's threaded outlet. Hand-tighten the nut until it is snug. Then, using an adjustable wrench, give it a final quarter-turn to half-turn to create a seal. The rubber cone washer inside the supply line nut does most of the sealing, so it does not require excessive force.
