Each lateral is slotted to allow filtered water to pass through while retaining filter sand within the tank. A cracked or broken lateral allows sand to bypass the filtration media and enter the pool return lines — the most common cause of sand appearing in the pool. Replacing a damaged lateral with this exact OEM part restores the integrity of the lateral assembly and prevents media loss.\u003c\/p\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eWhen you have sand returning to the pool and open the tank to inspect, check every lateral in the assembly — not just the visibly damaged one. Laterals degrade at similar rates, and replacing a single broken lateral while leaving aged, brittle neighbors in place often leads to a repeat service call within the same season. While the tank is open and the sand is removed, it is also a practical time to inspect the standpipe O-ring and the multiport valve gasket for wear.\u003c\/p\u003e\u003c!-- wft:processed:manual:2026-03-30 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53912382636307,"sku":"154540Z","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-tr140-sand-filter-lateral-154540z-1.webp?v=1774525669","url":"https:\/\/poolaroo.com\/products\/pentair_154540z","provider":"Poolaroo","version":"1.0","type":"link"}
