Everything else on the chlorinator, the lid, the seal and the control, is built around it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy it wears out\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNothing else on the equipment pad holds chlorine at that concentration for that long. Over years the plastic hazes, crazes and eventually cracks. Once it does, the feeder weeps water onto the pad and the dose becomes unpredictable. Replacing the chamber returns the feeder to a sealed vessel without the cost of a whole new unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis listing is the chamber only. Confirm your feeder is in the 300 or 320 series, and plan to renew the lid seal at the same time since it will have been sitting against the old chamber.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48634789462228,"sku":"RAI-451-4024","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_bcaf5d70-7818-4185-8404-4805fad8fd70.jpg?v=1788837561","url":"https:\/\/www.activepoolsupply.com\/products\/chlorine-chamber","provider":"Active Pool Supply","version":"1.0","type":"link"}
