This is the genuine Fluidra replacement return tube for the Zodiac Ei2 iQ pH 12 salt chlorinator system. Made from polyethylene (PE), it measures 4 mm inner diameter \u00d7 6 mm outer diameter with a 2-metre length, providing the fluid pathway that carries pH-correction chemical from the dosing pump back through the system. Keeping this tube in good condition is essential for accurate, leak-free pH dosing and consistent water balance.<\/p>\n
This return tube is a spare part for the Fluidra Zodiac Ei2 iQ pH 12 salt chlorinator and its pH dosing kit. The Ei2 iQ pH range is a smart, connected salt electrolysis system featuring integrated pH regulation, Wi-Fi and Bluetooth connectivity via the Fluidra Pool app, and automatic chlorine production for pools. Always cross-reference with your unit’s parts diagram before ordering to confirm fitment with your specific model variant.<\/p>\n
Genuine Fluidra polyethylene tubing is manufactured to precise dimensional tolerances so it seats correctly on the dosing pump fittings with no gaps or kinks. Off-brand tubes may be incompatible with pH-correction chemicals (such as acid or CO\u2082 solutions), leading to premature deterioration, chemical leaks, or dosing inaccuracies. Using OEM parts also preserves your Fluidra warranty coverage.<\/p>\n
Replacement is straightforward: isolate the system from power and stop water flow before disconnecting the old tube. Cut the new 2 m tube to the required run length, push firmly onto the pump and injector fittings, and secure any clips. Always follow the installation guidance in the Ei2 iQ user manual and ensure the system is fully purged before returning it to automatic operation.<\/p>","protected":false},"excerpt":{"rendered":"
