Zodiac X7 T Bar Diaphram

Suction cleaners use a diaphragm to turn suction into movement. The diaphragm is what creates the suction and release movement in certain models of pool cleaners. It works similar to a heart valve, it builds pressure, then releases it, builds pressure, releases it and so on. Over time this part can tear, stretch, or deform due to use it can cause the cleaner to stop moving.
