It is supplied as a complete underdrain set, hub and laterals together.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the underdrain does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe laterals are the slotted arms at the bottom of the tank. They draw filtered water evenly from across the whole sand bed and pass it to the hub, which feeds the standpipe and the outlet. Even collection is what makes the entire depth of the sand do filtering work instead of water channelling through one path.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSand appearing in the pool after a backwash or during normal running is the classic sign. Slots widen with age, arms crack and the hub can split, and any of those lets media straight into the returns. Because the parts age together, replacing the whole assembly is more reliable than swapping one broken lateral.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoing the job\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe assembly sits under the sand, so the media has to come out before you can reach it. Plan this repair alongside a sand change rather than as a separate visit.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":48627695648980,"sku":"R0520200","price":126.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_f5c2f2c0-9f92-4f54-9a1b-a9880d808ff4.jpg?v=1788726704","url":"https:\/\/www.activepoolsupply.com\/products\/hub-assembly-w-24-laterals-js60","provider":"Active Pool Supply","version":"1.0","type":"link"}
