Draining the hot water heater by using the low point drains can allow bits of anode and calcium nodules to be sucked into the cold water pipes. In the spring when you de-winterize, that crud gets blown throughout your plumbing. If cleaning your aerators does not fix this issue, you may need to remove the valve stems and flush out the lines.
