Zodiac – Bottom cover Ph & Dual – R0743500

The Zodiac R0743500 is an original replacement bottom cover designed for use with Zodiac’s TRI pH and TRI Dual chemical dosing systems. This cover forms the lower housing of the dosing unit, providing a secure and protective enclosure for the internal components of the pH and dual treatment system. As a genuine Zodiac OEM spare part, it is manufactured to the exact specifications of the original component, ensuring a precise fit and reliable performance when used as a replacement in your existing setup.

The bottom cover plays a critical structural role in the TRI pH and TRI Dual systems, protecting sensitive internal mechanisms — including the peristaltic pump head and associated dosing components — from moisture, chemical exposure, and environmental debris. The cover is designed to integrate seamlessly with the existing housing assembly, allowing straightforward replacement without the need for specialist tools or modifications. The use of a genuine Zodiac replacement component ensures compatibility with the locking mechanisms, sealing surfaces, and mounting points of the original unit, reducing the risk of leaks or misalignment that may occur with non-OEM alternatives.

Compatibility and intended application

The R0743500 bottom cover is specifically designed for the Zodiac TRI pH and TRI Dual automatic chemical dosing systems, which are used in residential and light commercial swimming pools to maintain consistent water chemistry. These systems automatically dose pH-correcting chemicals and, in the case of the Dual version, a secondary treatment product, helping pool owners maintain safe and balanced water without manual intervention. This spare part is intended for pool professionals and technically confident owners who need to restore a damaged or worn housing component to full working order, extending the operational life of the dosing system rather than replacing the entire unit.
