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

Relatively easy to install. No leaks and running like a champ. Great price based on my pool parts supplier

This chlorinator works great. We saved about $100 from the price of any local pool supply store. Easy to install.

Exact fit. I read other reviews on the knock off brand. This is exactly what I needed. It came with the extra hose as well. If you use 1 inch tabs use the bottom hole. If you use the 3 inch tabs use the top. Even came with libe for the O ring. Make sure you use Teflon tape and only hand tighten the lid so it won't get stuck on.

Had to replace one when adjacent pipe didn’t completely drain when winterizing pool equipment. The chlorinator itself wasn’t damaged, but the PVC pipe leading into it was cracked too close to it to be repaired/replaced without damaging the previous chlorinator.

Everything seemed great, had a pool company install for us as we had some pipe work that needed to be done and had them go ahead and install for us. In the photo I have included the feeder is leaking water where I have it circled in black. This is not a joint that screws on rather is cemented on from the looks of it. Waiting to hear back from the seller as he was very prompt in filling this order for us. I have left him a message but could see how to attach photo for him to see so have included here.

Product arrived early and in an actual pentair box. Exact replacement for the one the kids broke while roughhousing in the backyard. They broke the fitting that holds the external water line. Upon realizing the fitting was nearly 10 bucks I decided to replace the entire unit as it had developed a vacuum leak from a bad seal (which was another 8 bucks. I figured for 60 bucks more I could replace the entire unit and I should be good for another 8 years. Ten minute installation with great instructions. No leaks this far and is working as it should. On a side note if your main fitting below the feeder is still good, as mine was, you can simply unscrew the feeder from the supplied base and connect it to the old fitting. That is how I was able to install it in 10 minutes. Otherwise, I would have had to do some more pvc work and the installation time would have risen. Still easy but would have definitely been more time consuming. First two photos are the new feeder and the last photo is the one it replaced. Hope this helps!

I received (2) separate Pentair 320 Automatic chlorine feeders after returning the first one since I could not get the lid off because it was jammed on from being miss threaded. The second one was damaged and defective as the first one. Both of them had scratches from previous attempts to getthe lid off without success. I wasted (3) weeks waiting for this item to arrive while my pool was compromised. I spoke with the seller and they are aware of this widespread problem with this item.

24 minutes from delivery to installed! Removed the set screw from the bottom of my existing chlorine feeder, unscrewed it and the hose/etc. The new one was setup at the bottom vs. top, so I unscrewed the existing fittings on the new one (already wrapped in teflon tape btw - nice), screwed them in at the top, installed the plug, screwed on the feeder, and put in the set screw. From delivery to feeding chlorine in under 30 minutes. NICE!

Works great, for my pool I almost always have to have it set to 5 on the dial, but that is okay. I did have to run the fill tube to the top port, the bottom one didn't seem to do much if anything, but the longer tube was supplied and took about 5 minutes to change.
