underpressurized
Lacking adequate pressure
Underpressurized describes something with lower internal pressure than normal or required.
Aircraft cabins become underpressurized when pressurization systems fail, creating dangerous conditions at high altitude.
Tires, tanks, and hydraulic systems can all be underpressurized, typically indicating a leak or malfunction: The warning light indicated the fuel tank was underpressurized.
