Fluidra - pH Dosing Pump Suction Tube 4×6 mm PVC 2 m – Zodiac Ei2 iQ

Fluidra – pH Dosing Pump Suction Tube 4×6 mm PVC 2 m – Zodiac Ei2 iQ

This is the genuine Fluidra replacement suction tube for the integrated pH dosing pump on the Zodiac Ei2 iQ pH series salt chlorinators. The 2-metre flexible PVC tube draws pH-correction fluid — typically a liquid acid — from the chemical storage canister into the peristaltic dosing pump, enabling the system to regulate pool water pH automatically. Replacing a worn or damaged suction tube restores accurate chemical dosing and helps protect the pump from dry-running.

Compatibility

This suction tube is a spare part for the Fluidra Zodiac Ei2 iQ pH EVO range of salt chlorinators (Ei2 iQ 12 pH EVO, Ei2 iQ 20 pH EVO, and Ei2 iQ 25 pH EVO), which feature an integrated pH dosing pump for automatic water balance management. Always cross-reference your unit’s model number and parts list before ordering to confirm fitment.

Why genuine matters

Genuine Fluidra tubing is manufactured to the exact 4 mm inner diameter and 6 mm outer diameter tolerances required for a leak-free, secure connection at both the canister foot filter and the pump inlet. Off-specification tubing can cause air ingestion, inaccurate dosing, or premature pump wear — all of which compromise water quality and system longevity.

Installation

Cut the tube to the required length if needed, then connect one end to the foot filter placed in the chemical canister and the other end to the suction inlet of the dosing pump. Ensure the tube runs without sharp kinks and that all connections are firmly seated. Installation should be carried out by a qualified pool technician, and all chemical-handling safety precautions must be observed when working with pH-correction fluids.
