A shut-off valve stops hot or cold water from travelling to a certain point in a building. Plumbers refer to this valve as a "gate valve" or "globe valve." They consider it "frozen" when it refuses to turn to the left or right with normal hand pressure.
Do not try to force the valve, as that could damage the valve and other pipe fittings. Repair the valve as soon as you can to prevent a serious leak. This is an easy maintenance job that involves using a few basic household tools.
Locate the valve that controls the flow of water to the stuck shut-off valve. Turn it to the "off" position. You can shut off hot water at the hot water tank and cold water at the shut-off near the water meter.

Soak the groove around the base of the handle stem with penetrating lubricant. Wait 15 minutes for the lubricant to penetrate.
