Zodiac W81710 Aboveground Cleaner Cassette Diaphragm – Replacement Part

What This Part Is Used For
This cassette diaphragm is used inside compatible Zodiac aboveground suction pool cleaners. It creates the pulsing action that drives cleaner movement and debris intake.

Why This Part Matters
A worn diaphragm reduces suction and causes the cleaner to stall or move erratically. Loss of pulse strength leads to poor coverage and missed debris. Replacing the diaphragm restores consistent cleaner motion.
