Put a zinc bar in the water path and it corrodes first, which is exactly what you want, because the corrosion is happening to a part designed to be thrown away rather than to fittings, fasteners and equipment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOnly the bar is consumed\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThat is the reason this listing exists. The housing stays in the plumbing and only the zinc inside it is replaced. When the bar has wasted down, thinned or begun to crumble, it has finished its job and a fresh one goes in. This is the Deluxe model bar, so check which Pool Defender is installed before ordering.\u003c\/p\u003e","brand":"CMP","offers":[{"title":"Default Title","offer_id":48633441452244,"sku":"CTM-451-1011","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_d6154ee5-7fdf-4cc5-be3a-699e93984144.jpg?v=1788801801","url":"https:\/\/www.activepoolsupply.com\/products\/replacement-zinc-bar-for-pool-defender-inline-zinc-anode","provider":"Active Pool Supply","version":"1.0","type":"link"}
