A failed or cracked standpipe allows unfiltered water — and in some cases, sand — to bypass the filter media and return directly to the pool. Replacing this assembly with the correct OEM part restores proper flow path integrity and protects downstream equipment from sand contamination.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e152226\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eSand filters are most commonly opened for standpipe service during seasonal startups and sand replacement. If you're removing the standpipe assembly, inspect the lateral assembly at the base while the tank is open — replacing worn laterals at the same time avoids a second disassembly. Also confirm your tank diameter is 26 inches before ordering; standpipe assemblies are not interchangeable between different tank sizes.\u003c\/p\u003e\u003c!-- wft:processed:manual:2026-03-30 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":51774100963603,"sku":"152226","price":112.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/PEN152226_0.jpg?v=1747698387","url":"https:\/\/poolaroo.com\/products\/pentair-sd80-standpipe-152226","provider":"Poolaroo","version":"1.0","type":"link"}
