Pentair Rainbow Off Line Chlorinator #300 In stock$14134
Quick overview
- Off line design The feeder mounts beside the equipment pad and plumbs into the line rather than sitting in it, so it can be serviced without opening the main plumbing.
- Takes 3 inch tablets Loads the standard 3 inch trichlor tablet used by most pools.
- Steady sanitizer A tablet feeder releases chlorine gradually instead of the peaks and dips that come with hand dosing.
- Rainbow 300 series The long running Rainbow 300 body, now sold under Pentair, part R171016.
- Less handling of chemicals Tablets go into the feeder chamber rather than being tossed into the skimmer or floated in the pool.
- Serviceable parts The lid o-ring and the check valve are stocked separately, so a leak does not mean a new feeder.

Product details
The Pentair Rainbow 300 is an off line chlorinator, part R171016. It holds 3 inch chlorine tablets and releases sanitizer into the circulation system at a controlled rate.
Why off line
An off line feeder is plumbed beside the return line rather than in the middle of it. A small amount of flow is diverted through the chamber, dissolves part of a tablet and carries the chlorine back into the pool. Because the feeder is not carrying full system flow, it can be shut off and opened for a refill without disturbing the rest of the pad.
Steadier chemistry
Hand dosing produces a spike after every treatment and a slow slide until the next one. A tablet feeder smooths that out, which keeps the residual closer to target and takes the daily chemical handling out of the routine.
Service
The lid o-ring and the tube check valve are stocked as separate parts, so the two items most likely to weep after a few seasons can be replaced on their own.
