Operational Check
A visual inspection of the following items should be done on a daily basis to
determine whether the air vent is operating properly or has failed.

Normal

closing (with no leakage) when no air is present in the
piping
Blocked
(Discharge Impossible)
: No air is discharged though air accumulates in the air
vent
Leakage
: Water is discharged or leaks through the air vent outlet
during closed position
