Why is there low or no suction?Updated 14 days ago

If there's a loss of suction while pumping, it could be for a variety of reasons. Follow the instructions below to diagnose the issue.

Test pump motor:

Separate the main body from the Collection Container, put the main body in the palm of your hand, and check whether there is suction in the palm of your hand. You should feel a slight suction. If you do not feel any suction, there could be a problem with the pump motor.

Test for proper installation:

Check the valve, diaphragm, and breast shield for damage and make sure they are properly connected. Disassemble and properly reassemble.

Check breast shield size:

Check to ensure use of the correct breast shield size. If any damage to the breast shield is apparent, replace with a new breast shield.
