White or gray particles
The faucet screens are clogged with white or gray particles that float in water
The particles are most likely the result of a disintegrating dip tube in your water heater. Some water heaters have a dip tube made of polypropylene or polyvinyl chloride that can disintegrate over time. Call a licensed plumber. Periodically remove the aerators/screens from the end of your faucets and clean them.
