Pentair R171218 Rainbow 320C Automatic In-Line Chlorine/Bromine Feeder For Pool And Spa - Amber Body

Producto sencillo i con grandes posibilidades. El visor transparente lo hace unico en su gama i obtimiza el mantenimiento del sistema. Muy recomendable un SPA i piscinas particulares donde la cloracion en el skimer presenta un consumo excesivo de cloro i su disolucion es irregular

This chlorine dispenser is awesome. Fill it and leave it. Easy to see how much chlorine is left. It’s made my pool maintenance so much easier. Make sure you get the back check valve to protect your pool heater.

Put the unit in (very straight forward) and put 3-3" tabs into service. Monitored with test strips and it appeared to be doing great. After about 5 days the chlorine began dropping and it didn't seem the tabs were dissolving. Upon reading numerous reviews here on Amazon, I went to check if there was water in the tab column and there wasn't (I couldn't tell by looking - I can now). So I vented the column by loosening the cap and re-torquing shut, increased the thru-put and let it go at that. Pump shuts down at 8:30 PM and starts at 8:30 AM. Next morning upon start the chamber did not fill until I vented it as before. I took the timer out of the mix to run 24/7. I ordered a 1/2" npt air vent (like used to vent water baseboard heating systems) and a 1/2" nipple, TEE and cap. Placed the the works on the unit and it works like a charm with no problems at morning restart. I ordered the air vent (cast bronze - $10-$12) through Amazon and the other components I bought at the nearest box store. Problem resolved. Pool is crystal clear and test strips all running in range. Beats hauling liquid Chlorine and it's good for 3+ weeks (12,000 gallon pool} on 8 tabs. I'll add that chlorine concentration to harm brass and bronze must be 100ppm and I have 3-5 ppm free chlorine at any time and as the tab chamber drains when the pump is off there is little chlorine dissolved during the off period.

havent installes yet, looks like good product. make sure you buy a check valve. I did not know i needed one or else it will wreck your heater

This is my first chemical feeder having always done it by hand. This unit has a "see through" compartment that holds several 3" chlorine tablets. Other reviewers have commented that this was a desirable feature and I tend to agree although I am sceptical of how well this is going to weather and stay "see through". This unit is well constructed with a easy to open top cover where the tablets get inserted. Standard arrangement woith a rubber "O" Ring to seal the cap to the chamber and silicone grease is supplied to keep the "O" Ring lubed. This has been installed and in service for a little over two weeks and seems to work well, keeping the chlorine level in the pool constant. I will make an addendum to this review after several months of use to update. Botton line; Same price as comparable units and has the "see through" design so you can easily tell when new chemiocal is to be added. Easy install. If you can work with plastic pipe and glue, this is a snap. Greta instruction manual. I would make this purchase again.
