PentairR171016 Rainbow 300 Automatic Chlorine/Bromine Off-Line Pool and Spa Feeder

I bought this to replace a previous model that had failed after 6 years of use. I probably would have only needed to replace the valves. The proviso model was pretty clogged up on the inside but I imagine that is just from years of use and debris from the tablets. Easy to install and works as I would expect.

Great product! Installed this for an indoor pool where the chlorine demand is low. I was able to turn it way down and get just the right amount of chlorination. The previous owner had installed a Hayward chlorinator which was better for outdoor pools and tended to over-chlorinate. Would highly recommend this product.

Same as the original.

Material is a bit cheap but works just perfectly. Like the fact that tubing is bigger than other brands. Will certainly clog less.

So I moved into this house. Old chlorinator broke, at the elbow check valve, while replacing a brittle water line.$120 for new at pool store, approx $65 on Amazon. No brainer, I spring for Amazon.Just got around to installing it today and the ball valve (part 20 in pic) broke, as in SNAPPED while I was turning it in place by hand.No pliers, no excessive force. Teflon tape used on threads, as noted in the directions. So this is some really weak brittle plastic evidently. Now I have to order a new elbow, and fish out the threads from the base of the chlorinator.Why 5 stars then? Cause it works awesome, the last one just became brittle from old age. I'm bummed about this elbow though.If you buy this, go super easy on this piece.
