Sometimes you may wish to connect your garden hose to a water line such as your kitchen faucet. One reason you may want to do this, is if you are a plant enthusiast: Instead of dragging a pitcher filled with water back and forth to your plants, you can just turn on the faucet and water all your plants at once. If you've tried to hook the hose up, you may realize that the connections don't match up. To connect a garden hose to a water line such as your kitchen faucet, you must buy an adapter.
Remove the kitchen faucet aeration tip by gently grabbing it with a pair of channel locks and unscrewing it. Don't squeeze too hard or you may kink it.
Insert the garden hose adapter into the kitchen faucet and screw it on to the threads by turning it clockwise. Tighten it with your pliers but make sure not to tighten it too much. A snug fit is best.
Screw your garden hose onto the adapter and tighten it until it is hand tight. Garden hoses have a washer in the female end, which seals the connection.
Make sure the hose is somewhere the water can flow and turn the faucet on. Check the faucet for leaks and make sure water comes out of the hose. Tighten the adapter a little if it leaks.
