About This Item
The Pentair 1/4 in. Corrosion Resistant Check Valve (R172323) is the OEM replacement check valve for the Pentair Rainbow Automatic Feeder series, including Models 300, 302, 300-19, and 300-29.
IMPORTANT: OPTIONAL COMPONENT — VERIFY YOUR CONFIGURATION
This check valve is listed as an optional component for the compatible feeder models below — it is not included as standard equipment on all units. Confirm whether your feeder's original configuration includes a check valve before ordering.
This check valve controls one-way flow through the feeder's 1/4 in. chemical delivery tubing. It prevents backflow within the feed line, protecting against reverse pressure that can disrupt chemical dosing and compromise the integrity of the feeder system.

Poolaroo Pro Tip
Because this check valve is listed as optional on the Rainbow 300-series feeders, not all units will have one installed from the factory. If your feeder was configured with a check valve at installation and you're now seeing backflow or inconsistent chemical delivery through the 1/4 in. feed line, this is the OEM replacement to restore proper one-way flow control. Check the exploded diagram in your feeder's installation manual to confirm whether your specific configuration included this part.
