Step 5 · Install the New Spout

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.

Now, install the new spout. For a THREAD-ON spout, wrap the pipe's threads with 2-3 layers of Teflon tape in a clockwise direction (so it doesn't unravel as you tighten). Then, screw the new spout on by hand until it is snug and facing down. If it's not tight when facing down, give it another full turn. For a SLIP-ON spout, check if your new spout comes with a plastic adapter. If so, slide it onto the copper pipe first. Then, slide the new spout over the pipe until it sits flush against the wall. Ensure the set screw hole is facing down. Use your Allen wrench or screwdriver to tighten the set screw until it is snug. Do not overtighten, as this can dent the copper pipe.
