I'm getting ready to replace the knob on the outdoor hose spigot of my house. Not having done much plumbing, is there anything unusual I need to know? (ie: do I have to turn the screw right instead of left to loosen, or anything odd and plumbing-specific like that?) Any tips welcome.

The handle's secured by a screw that you will turn counterclockwise to loosen. The handle's secured from twisting by splines so after you get the screw out pull straight up on the handle to remove. Good luck, Tom
