FNS Plus filter?\u003c\/h3\u003e\n\u003cp\u003eNo. Each tank size uses its own lid. The 36 sq. ft. FNSP36 takes part 170020 and the 48 sq. ft. FNSP48 takes 170021. Check the model number on your filter label before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eDoes it include the clamp band or o-ring?\u003c\/h3\u003e\n\u003cp\u003eNo. This is the lid only. The bulkhead o-ring and clamp band are separate parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know the lid is the problem?\u003c\/h3\u003e\n\u003cp\u003eTypical signs are water seeping from the seam at the clamp band after the o-ring has been replaced, visible cracking around the moulding, or a lid that will not seat evenly when the band is tightened.\u003c\/p\u003e\n\n\u003ch3\u003eIs any special tool needed?\u003c\/h3\u003e\n\u003cp\u003eNo. The filter must be depressurised and the clamp band removed first — always relieve pressure at the air relief valve before opening a filter tank.\u003c\/p\u003e\n\u003cdiv class=\"ps4u-faq\"\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhat size filter do I need?\u003c\/h3\u003e\n\u003cp\u003eFilter area is matched to pump flow rate, not to pool volume alone. An oversized filter runs longer between cleanings and puts less back pressure on the pump, which is why installers routinely size up rather than to the minimum.\u003c\/p\u003e\n\u003ch3\u003eWhat is the part number for this filter?\u003c\/h3\u003e\n\u003cp\u003ePentair lists this filter under part number 170022. Quote 170022 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.\u003c\/p\u003e\n\u003ch3\u003eHow do I know when to clean the filter?\u003c\/h3\u003e\n\u003cp\u003eNote the pressure on a clean filter, then clean when the gauge climbs roughly 8 to 10 PSI above that baseline. Cleaning on a fixed calendar instead of the gauge either wastes effort or lets flow drop far enough to strain the pump.\u003c\/p\u003e\n\u003ch3\u003eHow do I confirm this fits my equipment?\u003c\/h3\u003e\n\u003cp\u003eMatch the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.\u003c\/p\u003e\n\u003ch3\u003eDoes this listing include the internal filter elements?\u003c\/h3\u003e\n\u003cp\u003eCheck the specification section above. Filter tanks are sold both complete and as bodies without cartridges, grids or laterals, and those internals are a significant part of the replacement cost.\u003c\/p\u003e\n\u003ch3\u003eIs there a warranty on this filter?\u003c\/h3\u003e\n\u003cp\u003eIt carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":52814309785917,"sku":"170022","price":329.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/6741\/8429\/files\/pentair-170022-tan-tank-lid-for-fns-plus-de-filter-60-sq-ft-vita-pool-supply-8467408.png?v=1786382692","url":"https:\/\/poolsupply4u.com\/products\/pentair-170022-fns-plus-tank-lid-60-sq-ft-d-e-filter-fnsp60-genuine-oem","provider":"PoolSupply 4U","version":"1.0","type":"link"}
