{"product_id":"pentairwaterpoolandspainc_190035","title":"Pentair Standpipe Outlet Assembly for FNS Plus 36 sq ft Filter — FNS Plus Series | 190035","description":"\u003cp\u003eThe Pentair Standpipe Outlet Assembly (190035) is the OEM replacement standpipe outlet assembly for the Pentair FNS Plus 36 sq. ft. vertical grid D.E. filter. At 10-3\/8 inches tall, this is the correct standpipe for the 36 sq. ft. model — confirm your filter model before ordering, as standpipe assemblies are size-specific across the FNS Plus line.\u003c\/p\u003e\n\n\u003cp\u003eThe standpipe outlet assembly forms the central flow path inside the FNS Plus filter tank, directing filtered water from the grid assembly to the outlet port. A damaged or cracked standpipe allows unfiltered water to bypass the D.E. grids entirely, compromising water clarity and allowing D.E. media to pass into the pool return. Replacing a failed standpipe restores the filter's sealed internal flow path and returns the system to full filtration efficiency.\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;\"\u003e190035\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePart Name\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eAssembly, standpipe, outlet, 36 sq. ft. filter\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\u003eHeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e10-3\/8 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\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;\"\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFits Into\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\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eEquipment Line\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eModel \/ Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003ePentair\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eFNS Plus Filter — FNS Plus Series\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eFNS PLUS 36\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eStandpipe outlet assembly, 36 sq. ft. filter, 10-3\/8 in. tall\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cem\u003eCompatibility is based on Pentair parts documentation and available OEM records.

Before ordering, confirm your filter's square footage rating on the label affixed to the tank body. If D.E. powder is appearing in your pool returns, inspect the standpipe for hairline cracks at the outlet collar — this is the most common failure point and is often missed during a visual inspection at normal light angles.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53960099987731,"sku":"190035","price":82.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-standpipe-outlet-assembly-fns-plus-filter-fns-plus-series-190035.webp?v=1792448049","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_190035","provider":"Poolaroo","version":"1.0","type":"link"}
