Record maintenance information, including test results, material usage, and repairs made.
Disassemble and repair mechanical control devices or valves, such as regulators, thermostats, or hydrants, using power tools, hand tools, and cutting torches.
Calibrate instrumentation, such as meters, gauges, and regulators, for pressure, temperature, flow, and level.
Install, inspect and test electric meters, relays, and power sources to detect causes of malfunctions and inaccuracies, using hand tools and testing equipment.
Test valves and regulators for leaks and accurate temperature and pressure settings, using precision testing equipment.
Record meter readings and installation data on meter cards, work orders, or field service orders, or enter data into hand-held computers.
Turn meters on or off to establish or close service.
Shut off service and notify repair crews when major repairs are required, such as the replacement of underground pipes or wiring.
Install regulators and related equipment such as gas meters, odorization units, and gas pressure telemetering equipment.
Cut seats to receive new orifices, tap inspection ports, and perform other repairs to salvage usable materials, using hand tools and machine tools.
Turn valves to allow measured amounts of air or gas to pass through meters at specified flow rates.
