Overview

The Pentair R171096 Rainbow 320 feeder is an automatic in-line sanitation device that holds chlorine or bromine tablets and dispenses chemical steadily into pool water via the return line. Built with durable materials and multiple feed options (bottom or top), it's designed to deliver consistent chemical levels while minimizing user maintenance. Ideal for residential pools of moderate to large size.

What’s Included

  • Main feeder body and lid with reservoir for tablets
  • 2″ slip PVC fittings & adapter for 1-½″ line
  • Control valve to adjust chemical output
  • Check valve / elbow to prevent backflow
  • Optional extension tubing for top-feed use
  • User manual & warranty information

Compatibility & Replacements

This feeder is compatible with pool plumbing systems using 1-½″ or 2″ return lines. It replaces previous Rainbow feeders in the same product line (Model 320). For top-feed use ensure plumbing and mounting clearances support the extension. Use only slow-dissolving trichlor or bromine tablets for proper operation.

Installation & Notes

  • Install in return line (plumbed inline) ensuring flow direction aligns with feeder’s inlet/outlet.
  • Do not overtighten fittings; use proper PVC adhesives where necessary for slip fitting.
  • Ensure lid is sealed tightly to prevent spills and reduce fumes.
  • Clean and inspect check valve / elbow periodically; replace parts if signs of wear or corrosion occur.
  • During winterizing or shutdown seasons, remove tablets and rinse reservoir to prevent damage.
