Install and Tighten New Faucet

What happens here

Carefully insert the prepared new faucet into the threaded opening on the exterior wall, turning it clockwise to hand-tighten. Once hand-tight, go back inside the garage and hold the copper pipe securely with a crescent wrench to provide a backup. From the exterior, use channel locks or an adjustable wrench to firmly tighten the new faucet, ensuring it is straight and fully sealed. Avoid over-tightening to prevent damage to the pipe or faucet.

Goal: Thread the new faucet into the pipe opening on the exterior wall and securely tighten it while supporting the internal pipe.
