For instance, those valves come in either steel, or plastic handles AND steel or plastic valve stems. The stems break easily!

Always shut the main water off before trying.

Believe it or not, the pressure inside is contributing to the stuck-ness. Water pressure alone wouldn't be enough to stop it from turning on a healthy valve, but when you combine age, corrosion, etc, with pressure, and it may not turn.

So shut off the main water supply and relieve the pressure from that pipe by opening a faucet. Also, try lightly tapping on the top of the handle right on the screw that holds it on.

The nut below the handle holds the stem in. It may be possible that before you, someone may have tightened the snot out of that nut if it was leaking past the stem there. Tightening this nut too tight can make the valve impossible to turn. This is also the place where a plumber would take the valve apart if replacing just the
