How This Component Fits the System

Pool and spa service parts play an important role in keeping an installed system maintainable. Selecting the right replacement can restore intended operation without discarding equipment that is otherwise in good condition. The most reliable approach is to identify the component by its actual function, compare it with the removed part, and use the manufacturer’s equipment diagram when different versions are available.

Check the feeder variant and required connection points before installation. Use the tubing and fittings specified for the feeder and follow the feeder manufacturer’s chemical-handling instructions.

Replacement and Maintenance Considerations

A well-planned repair includes inspecting the condition of the neighboring assembly before reinstalling the replacement. Look for worn mating surfaces, loose retainers, damaged connections, corrosion, or other conditions relevant to the component being serviced. Recommission the system using the manufacturer procedure rather than assuming that installing a new part alone resolves the original operating problem.

For this particular listing, the ordering reference is R172269Z. The identifying description is Pentair Rainbow 300-29X Automatic Feeder Tubing [1/2" ID x 12ft] (R172269Z).
