Without it, milk could back up into the tubing and reach the motor, contaminating the milk and damaging the appliance. It's a safety feature as much as a performance one. Don't pump without it.
Disassemble the three parts, wash in hot soapy water or steam sterilize. Check that the silicone diaphragm is intact before reassembly. Air dry.
