The faucet screens are clogged with white/gray particles that float in the 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 plumber. Periodically remove the screens from the faucets and clean them.
The faucet screens are clogged with white/gray particles that sink in the water - The particles are likely calcium carbonate. Your water heater may need routine maintenance. Consult the owner's manual. Periodically remove the screens from faucets and clean them. If the particles persist, call the Fairhaven Water Department.
Pink growth on bathroom fixtures - The pink growth or stain is the result of a mold or a bacterium, specifically, Serratia marcescens. The mold is present in the air. Mold and bacteria grow wherever there is a warm, moist or humid environment, like a tub or showerhead. The mold and bacteria feed on the small quantities of nutrients in water. Regular cleaning with bleach or a cleaner that removes mildew will clear the mold. Wipe away any standing water to reduce growth. Certain materials, like rubber, plastic gaskets, etc., contain nutrients that help these organisms grow.
