If the water flow from your faucet has lost its spritz, you may need to clean or replace the aerator. That's the little thingy that screws into the end of your spout. It usually has a screen or other type insert with tiny little holes, which can get clogged my mineral deposits and other stuff from your water lines that you probably don't want to know about. If your water pressure is OK but going off in all directions, that's a sign your aerator needs to be cleaned. You can usually get this done by soaking the aerator's innards in some white vinegar for about an hour. If that doesn't work, take off your aerator and go to a home center or plumbing supply and buy a replacement.
