Product details

The Pentair Rainbow R172435 is the 1 inch check ball for HC series automatic chlorine feeders, covering models HC-3315, HC-3330 and 3340.

What it does

The ball is the moving part of the feeder check. It lifts to let flow through and seats to stop it coming back. When it is worn, distorted or missing, the feeder can no longer hold that check and the system behaves oddly around the feeder line.

Worth doing while you are in there

This is a low cost part, so it is normally replaced any time the feeder is opened for service rather than inspected and put back.

Questions and answers

What people ask about this product, answered by our pool techs.

Which feeders does this fit?
Pentair Rainbow automatic feeders in the HC series, listed as models HC-3315, HC-3330 and 3340.
What does the check ball do?
It seats to stop flow going back through the feeder, so the check function works only when the ball is in good shape.
Is it a genuine Pentair part?
Yes. It is the Pentair Rainbow OEM check ball, part R172435.
How many do I need?
One ball per check location. If you are servicing the feeder anyway, inspect the suction screen at the same time since it sits in the same area.
