The air/water valve may stick at first, but it should operate
smoothly after it is depressed a few times.
Attaching the biopsy valve
If a biopsy valve is not properly connected to the instrument
channel port, it can reduce the efficacy of the endoscope’s
suction system, and leak or spray patient debris, posing an
infection control risk.
Attach the biopsy valve to the instrument channel port of the endoscope (see
Figure 3.13). Confirm that the biopsy valve fits properly.
