Pump Backflow Valve

Our backflow valve helps protect your breast pump and tubing from milk and moisture, maintaining hygienic and efficient pumping sessions. Choose between the full 3-piece valve set (base, cap, and membrane) or replacement membranes only — both designed to fit perfectly with our Flow & Flourish accessory kit and most Spectra-style pumps. For optimal performance, we recommend replacing the silicone membrane every 1–3 months (or sooner if you notice reduced suction or visible wear).
