How do I make a faucet pour instead of spray?
Sounds like the screen in the aerator needs to be cleaned out. To clean the screen unscrew the aerator by hand, do not use a tool such as channel locks to do so because you'll mar the surface. This is what you might typically see in an aerator:



Disassemble the aerator and clean everything, if you can see through each hole in the mesh screen it should usually work like the properly functioning sink. When reassembling make sure the screen sits properly in the aerator body, the bushing shown in the diagram is to create a gap between the mixer and the screen, in most cases if they are directly touching you will not be getting a good stream from your faucet.

Hope that helps.
