ELVIE ELVIE PUMP Leaking Milk

Elvie Breast Shields (2-Pack)

Repeated exposure to high-heat sterilization causes the polymer to warp, preventing a flush fit against the pump hub. This creates a gap in the vacuum seal that fails specifically during movement or postural changes, allowing milk to escape the flange area. Replacing the warped shields restores the original geometric tolerances required for a leak-proof seal.

Elvie Valves & Spouts

The silicone valves regulate one-way milk flow into the bottle; if the material loses elasticity or becomes misshapen, it allows for backflow and internal leaking. If milk enters the suction channel via a faulty valve, the pressure differential is compromised, leading to leakage around the hub's exterior. These are considered high-wear consumables that require regular replacement to maintain fluid circuit integrity.

Elvie Bottles (3-Pack)

The top rim of the bottle acts as the secondary sealing surface against the hub's gasket. If the bottle has been misshapen by heat or the release-button interface is worn, the clamping force is insufficient to contain milk while the user is in motion. New bottles ensure the locking mechanism provides enough compression on the seals to prevent leaks.
