It threads onto the top of the chlorinator body and raises it, giving the unit room for more chlorine tablets.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy owners add one\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA standard Rainbow body only holds so many tablets, so a busy pool in mid summer can run the chlorinator dry in a matter of days. The extension buys back capacity without replacing the chlorinator, which means fewer trips to the pad and a steadier chlorine feed through the hottest weeks of the season.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe extension screws on between the chlorinator body and the existing cap, so the original threaded cap and lid o-ring stay in use on top. Inspect that o-ring while the unit is open, since a tired seal is the usual cause of a chlorinator that leaks or will not hold pressure after service.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48628787609812,"sku":"RAI-451-4988","price":48.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_d30224c4-2c13-43f9-9158-04651582fa06.jpg?v=1788750712","url":"https:\/\/www.activepoolsupply.com\/products\/rainbow-chlorinator-extension-10","provider":"Active Pool Supply","version":"1.0","type":"link"}
