Is your faucet pressure not what it used to be?  Unscrew the nozzle and clear out the aerator (the little screen at the end of the faucet).  While you are there, check for a worn washer at the spout.  Both a worn washer and a dirty aerator can cause low flow.  (If you find white flecks of plasticy stuff in your aerator it’s a sign that your water heater is falling apart).
