Juch asks: I'm trying to turn my hose spigots off, but I'm having issues. The main issue is that one of the valves is stuck (see image). When I went to turn it off it was missing a handle, so I went out and bought a replacement. When I turn the handle, it just spins against the shaft but doesn't turn it, so the valve doesn't shut. My second spigot won't close all the way (not pictured, but I can get an image if it matters to anyone). The handle is turned as far as I can make it go, but water still drips out of the spigot when I leave it open. I appreciate any advice on how to fix either of these issues.
EZ-C heroically answers:
Those gate valves should be replaced with 1/4 turn ball valves anyway. I'd cut it out and put in new valves.
What is pictured is soldered copper which you probably don't want to work with. Instead you can use sharkbite fittings to work with the copper pipe. Very simple to use.
Shut off the water at the meter. Get a cheap pipe cutter. Cut pipe, use sharkbite fitting / valve. Turn water back on. Done.
