It is supplied complete with the zinc anode, the thru rod, a new cap and an O-ring, so the whole assembly is renewed rather than only the zinc.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow a sacrificial anode works\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eZinc sits low enough on the galvanic scale that it corrodes before the other metals in a pool. That is the whole point of it. The anode gives itself up to the water chemistry so ladders, rails, light rings and other metal hardware do not.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA zinc anode is a wear item. Plan on replacing it about every three years, and inspect it sooner if the pool has had heavy chemical swings. The practical rule is size: once the anode has been eaten down to roughly half of what it was when new, it no longer has enough zinc left to protect anything and should be changed.\u003c\/p\u003e","brand":"Pool Tool","offers":[{"title":"Default Title","offer_id":48625784062164,"sku":"PTE-45-9800","price":71.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_31bb66f2-f80d-4bb8-86d4-9b221af15458.png?v=1788692162","url":"https:\/\/www.activepoolsupply.com\/products\/pool-tool-104r-kit-zinc-anode-replacement-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
