Could a failing Willow Go Duckbill Valves cause the WILLOW WILLOW GO to have symptom: Leaking?

The duckbill valve is a silicone one-way check valve that manages fluid directionality. Over time, the silicone undergoes cyclic fatigue or accumulates microscopic milk protein buildup, which prevents the 'lips' of the valve from closing completely. This failure in the fluidic seal allows expressed milk to bypass the collection chamber and leak externally.

Could a failing Willow Go Diaphragms cause the WILLOW WILLOW GO to have symptom: Leaking?

The diaphragm is the electromechanical interface that separates the motor's vacuum pulse from the milk-contact components. If the diaphragm is not seated perfectly or has lost its elastic modulus due to repeated sterilization, the vacuum seal is compromised. This loss of negative pressure prevents milk from being properly pulled into the container, leading to pooling and subsequent leakage.

Could a failing Willow Go Breast Milk Containers cause the WILLOW WILLOW GO to have symptom: Leaking?

The rigid plastic housing of the container must maintain precise tolerances to interface with the silicone seals. Thermal stress from dishwashers or steam bags can cause subtle warping of the plastic mating faces. When these faces are no longer perfectly planar, the gaskets cannot achieve a water-tight seal under the pressure of the expression cycle.
