Maytronics 9980891 Dolphin Non Return Flap, M4 / M5 / Wave 2010
Genuine OEM one-way flap that keeps debris in the basket.
The Maytronics 9980891 Dolphin Non Return Flap (PST-DL9980891) is the genuine OEM one-way valve that seats inside the filter intake on Dolphin robotic pool cleaners. It opens to let debris in during the cleaning cycle and closes when the robot pauses or lifts out of the pool, so leaves, sand, and fine grit stay locked in the basket. Replace yours when you notice debris falling out at the end of a cycle or when the rubber flap looks warped, torn, or stiff from chlorine exposure.
