Hi AnMarie. There are instructions in the manual. The key is to remove all other sources of water. Then show the chickens the valves by tapping on them with your finger to release some waterer. This will attract their attention. You may need to do this several times. The best time to try is in the morning right after they have eaten their dry pellets. They will be thirsty. Be patient and your chickens will learn to use the waterer. The valve technology is very well tested and we've sold tens of thousands of them. Your chickens will adapt.
