The bottom line: this chlorinator is best for backyard pools or spas that need a closed, circulating feeder able to hold either 11 large or up to 98 small chlorine or bromine tablets, and its strongest selling point is the practical combination of a sealed cover, venting plug and an adjustable control valve that make dosing straightforward when installed correctly.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosed circulating system:\u003c\/strong\u003e The feeder uses a closed system to circulate water and deliver controlled chlorination while helping the pool filtration work efficiently.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible tablet capacity:\u003c\/strong\u003e It accepts 11 large or 98 small chlorine\/bromine tablets so users can size dosing to pools or spas of different volumes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed cover with gasket:\u003c\/strong\u003e The cover includes a white thickened gasket to improve sealing and reduce the chance of external leaks when fitted and lubricated properly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop vent plug:\u003c\/strong\u003e A vent plug releases built-up gas from tablet reactions to avoid excessive internal air pressure and helps maintain consistent operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl valve and bottom drain:\u003c\/strong\u003e The included control valve lets you regulate or stop flow and the bottom drain allows quick discharge of remaining liquid for cleaning or winterization.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable ABS construction:\u003c\/strong\u003e Thickened inner walls and oxidation-resistant ABS material aim to extend service life compared with thinner alternatives.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis chlorinator is well suited to homeowners and small commercial operators who already use a Rainbow 320 style feeder or need a compatible inline tablet feeder that can handle a broad range of pool sizes, from several thousand up to tens of thousands of gallons depending on feed type. It is a practical option for those who want a physical tablet feeder with manual flow control and easy access for refills.\u003c\/p\u003e\n\u003cp\u003eIt is less appropriate for users who need a fully automated chemical control system or who are unable to maintain weekly cleaning and lubrication; the unit requires periodic lubrication of the lid and valve and weekly hose\/feeder cleaning to avoid blockages and corrosion. Also note reports of seal or valve issues following freeze events, so those in freezing climates should winterize carefully or choose a freeze-resistant solution.\u003c\/p\u003e\n\u003ch2\u003ePros \u0026amp; Cons\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003ePros\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAccepts multiple tablet sizes, making dosing adaptable to a wide range of pool and spa volumes.\u003c\/li\u003e\n\u003cli\u003eGood sealing design with thickened gasket and vent plug to manage pressure and reduce leaks when maintained.\u003c\/li\u003e\n\u003cli\u003eControl valve and bottom drain simplify flow regulation and service tasks like draining and cleaning.\u003c\/li\u003e\n\u003cli\u003eDurable ABS construction with thickened barrel walls for improved oxidation resistance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCons\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSome users report seal or valve problems, especially after freezing conditions, so winter care is required.\u003c\/li\u003e\n\u003cli\u003eRequires regular lubrication and cleaning to maintain reliable operation, which is additional maintenance compared with fully automated systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel compatibility\u003c\/td\u003e\n\u003ctd\u003eCompatible with Rainbow 320 style chlorinator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTablet capacity\u003c\/td\u003e\n\u003ctd\u003e11 large or 98 small chlorine\/bromine tablets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePool capacity range\u003c\/td\u003e\n\u003ctd\u003eBottom feed: ~6,500 to 27,000 gallons; Top feed: ~18,000 to 70,000 gallons\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh-quality ABS with thickened inner wall\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNotable parts\u003c\/td\u003e\n\u003ctd\u003eTop vent plug, control valve, bottom drain, 1\/4-in feed hose\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncluded maintenance items\u003c\/td\u003e\n\u003ctd\u003eLubricating oil and necessary accessories for installation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eOur Verdict\u003c\/h2\u003e\n\u003cp\u003eThe Upgraded 320 Pool Chlorinator Inline Feeder is a practical, value-minded replacement for users who want a tablet-based feeder with solid design features like a gasketed lid, vent plug and drain.
