This one is 32-1\/16\" long. Check the model on your filter label before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eDoes my filter pre-date November 1998?\u003c\/h3\u003e\n\u003cp\u003eFilters made before 11\/98 use a different cartridge — typically the Unicel C-7498. Check the date stamp on the tank if you are unsure.\u003c\/p\u003e\n\n\u003ch3\u003eShould I replace all four at once?\u003c\/h3\u003e\n\u003cp\u003eYes. Mixing new and worn elements causes uneven loading and shortens the life of the new cartridges.\u003c\/p\u003e\n\n\u003ch3\u003eHow long does it last?\u003c\/h3\u003e\n\u003cp\u003eTypically two to three seasons with regular rinsing and periodic deep cleaning, though this varies with bather load and water chemistry.\u003c\/p\u003e\n\u003cdiv class=\"ps4u-faq\"\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eHow often should a filter cartridge be replaced?\u003c\/h3\u003e\n\u003cp\u003eMost cartridges are cleaned several times a season and replaced when the pleats no longer come clean, the fabric goes hard or brittle, or the end caps separate. Filter pressure that returns to high shortly after a cleaning is the usual sign that the element is finished.\u003c\/p\u003e\n\u003ch3\u003eWhat is the part number for this filter cartridge?\u003c\/h3\u003e\n\u003cp\u003ePentair lists this filter cartridge under part number 17378. Quote 17378 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 clean this cartridge?\u003c\/h3\u003e\n\u003cp\u003eRinse between the pleats with a garden hose, working top to bottom, and soak in a dedicated filter cleaner to remove oils and scale. Avoid a pressure washer, which drives debris deeper into the fabric and cuts the pleats.\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\u003eWill this cartridge fit my filter housing?\u003c\/h3\u003e\n\u003cp\u003eCartridges are matched by outside diameter, length, end-cap style and square footage, all of which are listed in the specification section. Compare those four dimensions against your existing element - the filter's brand name on its own is not enough to confirm a fit.\u003c\/p\u003e\n\u003ch3\u003eIs there a warranty on this filter cartridge?\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":52854167142717,"sku":"17378","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/6741\/8429\/files\/R173578-001__77022.1616676854.jpg?v=1786993623","url":"https:\/\/poolsupply4u.com\/products\/pentair-clean-clear-plus-520-replacement-cartridges-4-pack-130-sq-ft-each-ccp520-genuine-oem","provider":"PoolSupply 4U","version":"1.0","type":"link"}
