Underneath the sink there should be two valves - one for the hot water, and one for the cold water. If there are none, find where your water line enters the home (usually in the basement) and there should be a valve there that you can close. If you do, remember that you have shut off all the water in the house including the toilet (s). Also remember to open the kitchen sink faucet (hot and cold) to drain what water remains in the pipes before attempting to service the faucet (if that's what you're doing). Also, whenever operating these pipe valves (whether opening or closing), turn them as far as they will go, then reverse about 1/8 of a turn. This will allow a little wiggle room (you can budge in both directions) when you have to operate the valve at a much later time and it has become stiff.
