{"product_id":"valve-spring-washer","title":"Pentair 1\" White Valve Spring Washer","description":"\u003cp\u003eThe Pentair 271160 is the white valve spring washer used in the multiport valve stem assembly. It measures 1-5\/8 inches outside diameter, 1-1\/4 inches inside diameter and 3\/32 of an inch thick.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it sits\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA multiport valve seals because a spring holds the rotor down against the seat. The washer is part of that stack, spreading the spring load so the stem assembly stays square. When it is missing, cracked or has been replaced with something close but not right, the rotor no longer seats evenly and water crosses between ports, which is the classic symptom of sand or DE returning to the pool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck the size before ordering\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe product name refers to a 1 inch valve spring washer, and the part detail lists it for the HiFlow 2 inch top mount and side mount multiport valve. Both readings are carried here, so measure your old washer against the dimensions above rather than going by valve size alone.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRebuild the stack together\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe spring, the stem o-ring and the valve top o-ring wear on the same schedule as this washer. They are separate parts, and doing them at once means opening the valve once.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627569557716,"sku":"PAC-061-2416","price":14.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_b9502279-8d1d-4f6a-af73-e564b08d1dad.jpg?v=1788723742","url":"https:\/\/www.activepoolsupply.com\/products\/valve-spring-washer","provider":"Active Pool Supply","version":"1.0","type":"link"}
