Pentair R171096 Rainbow 320 Automatic in-Line Chlorine/Bromine Feeder for Pool and Spa

I had a 7-yr old chlorinator (off-brand copy of the Pentair 320), and it was starting to have issues with the check valve and the chlorine control valve. I could have bought parts separately but the cost was getting close to a full swap.I decided a new one was needed and I couldn’t be happier. Since I chose to keep the diverter tee to avoid disconnecting existing flow tubes, that meant I needed to change out the flex tube, spring and its fittings which was super easy.I added a little more plumbing tape when I rethreaded the tube fixtures to the control valve and housing body, just to be safe. Be patient, the housing will fit and you can tighten enough to keep the orientation of the tube.The little screw that keeps the housing from spinning was tedious, and probably took 10 minutes itself to get reseeded. But it was just a tight fit for my equipment, not the fault of the screw necessarily.The entire swap took less than 30 minutes (if that), including salvaging some existing tabs. Be careful of the dangerous fumes from the existing equipment and old tablets, please wear a mask or keep your breathing protected.Very pleased with experience thus far.

Works great! Easy to replace

Easy and price was fair. Delivered quickly. Quality product. Will use them again for next problem to fix.

Great product easy to install no issues

I like the product but I have two complaints. The first one is I had to use two band wrenches just to get the top off. Don’t know how they put it on there, but it took a lot to get that top off initially, also I cannot get the little screen to stay on the four tabs on the bottom every time I manage to get it on it pops off

Exact replacement

We needed for our pool this summer and it has been working good.

Works good
