Frequently Asked Questions

How do I know if my diaphragm needs replacing?

If your Baracuda X7, T5, or T3 is not moving, first check and clean your pool filtration. Then remove the cleaner head from the hose and test suction with your hand over the hose while the pump runs — or use a Pool Pulse gauge (ideal reading 2–3). If suction is fine but the cleaner still won’t move, disassemble the cleaner and inspect the diaphragm for holes or tears. Any hole in the rubber will allow water to bypass the mechanism and stop the cleaner working.

What makes the Duralife diaphragm better than the standard?

The Duralife uses a reinforced, shorter design that is engineered to withstand pool chemical exposure and mechanical stress better than the traditional Zodiac diaphragm, resulting in a longer service life.
