Just serviced 5 hydrants in Brentwood business district. Flushed all units to remove sediment. Lubricated stems and checked for proper operation. Replaced worn gasket on one unit (hydrant #BW-42) that showed minor leakage. Flow tested all hydrants - pressure readings within normal range (52-58 PSI). Painted two hydrants that had faded color coding. All caps secure and accessible. Updated GIS database with maintenance records. All hydrants now ready for emergency use.
