It’s engineered for ease-of-use: simply drop it into the central post of your manifold during rebuild or maintenance. Because the spring is properly tensioned, it helps the filter maintain consistent flow and avoids cartridge shifting or bypass. No adjustments or calibration required beyond standard reassembly.\u003c\/p\u003e\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eInspect the spring end-caps for wear when replacing. Pair with a new manifold O-ring or manifold bolt for a complete rebuild. Many users replace the spring when re-sealing the tank.\u003c\/p\u003e\n\u003ch3\u003eInstallation Tips\u003c\/h3\u003e\n\u003cp\u003eEnsure pump is off and system depressurized before opening the filter. Position the spring concentrically in the manifold tube; avoid bending. Confirm cartridge tops are seated before reassembling tank. Always use new O-rings or lubricated seals when reassembling.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":46826751557798,"sku":"178616","price":7.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/9698\/1414\/files\/spring_b7492d80-2db9-4961-9022-be70a5ea540b.jpg?v=1762806282","url":"https:\/\/kypoolsupply.com\/products\/pentair-clean-and-clear-plus-520-cartridge-filter-pentair-compression-spring-for-clean-clear-quad-178616","provider":"Kentucky Pool Supply","version":"1.0","type":"link"}
