- Inspecting valve chambers, hydrant pits, LPDs, and HPV pit boxes for cleanliness and structural condition.
- Conducting static and dynamic testing of hydrant pit valves to ensure proper operation.
- Monitoring and recording wear on QRV seats for preventive maintenance.
- Monitoring differential pressure (DP) across filter vessels to assess element condition.
- Performing DBB (Double Block and Bleed) monitoring to detect valve leakage.
- Carrying out venting and draining of LPDs and HPVs, including flushing of dormant pits.
- Conducting flushing of dormant reel hoses and over-wing nozzles to maintain fuel cleanliness.
- Executing in-house calibration of hydrometers, thermometers, and stopwatches against reference units.
