If your multiport valve handle is not returning to position correctly, fails to hold its selected port, or feels loose during operation, this spring is the service part to restore proper valve function.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\n\u003cp\u003eThe valve spring applies the return tension that holds the rotor assembly firmly against the selected port position in a multiport valve. A fatigued or broken spring allows the rotor to shift under system pressure, causing water to bypass the selected port — resulting in unfiltered water returning to the pool, backwash cycling incorrectly, or the handle failing to lock into position. Replacing this spring restores the mechanical engagement that keeps the valve operating as designed.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\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;\"\u003e271161Z\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePart Type\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eMultiPort Valve Spring\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eCompatible Valve Size\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e1-1\/2\" and 2\"\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eValve Mount Type\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eTop Mount and Side Mount\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e1\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\n\u003cp\u003eWhen replacing the valve spring, inspect the rotor O-ring and the key assembly at the same time — these components wear at similar rates and are inexpensive to replace while the valve is already disassembled. Addressing all wear components in a single service visit prevents a repeat teardown shortly after. Match the part number 271161Z against your valve's exploded diagram before ordering to confirm this is the correct spring for your specific HiFlow model.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53960101036307,"sku":"271161Z","price":55.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-multiport-valve-spring-1-1-2-and-2-hiflow-multiport-valve-271161z.webp?v=1776728831","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_271161z","provider":"Poolaroo","version":"1.0","type":"link"}
