How often should the backflow protector be replaced?

Most moms replace it around every 6 months with regular use, sooner if you notice any damage to the silicone membrane inside, like tears, stretching, or a seal that doesn't sit right. It wears more slowly than parts like duckbill valves, but it's still worth checking periodically.

Which Spectra pumps is this backflow protector compatible with?

This backflow protector is compatible with Spectra S1, S2, 9 Plus, and Synergy Gold (SG) pumps. It's built to match the fit and function of the original part across all four models.

Do I need one or two backflow protectors?

If you're double pumping, you'll need two, one for each side!

Wash before first use and after each use with warm water and mild soap. Rinse well and air dry completely before reassembling. Avoid forcing it apart or twisting too hard during removal, since this can wear down the fit over time.

Made from BPA-free, food-grade materials. Replace regularly, or sooner if you notice any damage to the silicone membrane inside. As with all small parts, keep away from children under 3 years.

What are Backflow Protectors for

The backflow protector creates a barrier between expressed milk and the pump motor, helping keep the motor clean and dry during pumping. It's a key part of Spectra's closed system, and it plays a real role in how consistently your pump performs over time. If you're pumping daily, most moms find it holds up well for about 6 months, sooner if you notice any damage to the silicone membrane inside.
