Maytronics Non Return Flap Diag. Grey (9985280)
This genuine Maytronics Non-Return Flap (Gray, part number 9985280) is a replacement check-valve component designed for various Maytronics/Dolphin robotic pool cleaners, particularly in the “Diagnostic” or earlier model families. It prevents back-flow of debris and water when the cleaner stops suction, helping maintain cleaning efficiency and system integrity.
Key Features
OEM replacement part – Designed to meet Maytronics’ original specifications for fit and material compatibility, ensuring proper performance in compatible units.
Check-valve / non-return design – Allows water and debris to flow into the cleaner’s basket or chamber during operation, then closes to prevent debris from escaping or water from reversing when the motor stops.
Durable, pool-rated construction – Made from flexible, gray plastic engineered to withstand exposure to pool water, chemicals, wear and repeated cleaning cycles.
Cost-effective maintenance item – A small but vital internal part: replacing a worn or damaged flap can restore proper debris retention without needing to replace an entire assembly.
