The handle of a faucet is connected to the valve stem with a screw. The handle turns the valve stem when it is engaged, controlling the flow of water. Sometimes the faucet handle does not turn easily because the screw has tightened with use. Solving the problem of a tight faucet handle is accomplished by following a straightforward procedure that is completed in less than 15 minutes, even by the novice.
Cut the water supply to the faucet handle by turning the shut-off valve clockwise. If no individual shut-off valves are under the sink, use the main water shutoff for the house, often located near the street or water meter.
Locate the button cap on top of the tight faucet handle. The cap may have an "H" or a "C" imprinted on it, denoting hot or cold.
Pry off the button cap with the standard screwdriver. Insert the blade of the screwdriver under the edge of the button cap and gently lift it.
Unscrew the screw in the center of the handle, using the Phillips screwdriver. Turn the screw counterclockwise until it is completely detached from the valve stem. Pull off the handle.
Apply plumber's grease into the cavity of the faucet handle around the valve stem. Use your fingers to apply the grease.
Place the handle onto the valve stem and reinsert the screw by turning it clockwise with the Phillips screwdriver. Snap the button cap onto the handle and turn on the water supply.
