The o-ring is what keeps it sealed, and it does not last forever: heat, chlorine and the repeated squash of the lid flatten it, then it hardens and cracks. When that happens the pump struggles to prime, air collects in the basket, and flow drops. Owners often chase the problem into the plumbing when the seal is the whole story.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eClean the groove and the lid face before you seat the new o-ring, and use a silicone based o-ring lubricant. That helps it seat evenly, keeps the rubber supple through the season and stops the lid gluing itself down before the next basket clean.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48634474070228,"sku":"HAY-101-1532","price":45.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_3b794408-24fc-4482-a17d-9f83fb9341e1.jpg?v=1788831905","url":"https:\/\/www.activepoolsupply.com\/products\/strainer-cover-o-ring-1","provider":"Active Pool Supply","version":"1.0","type":"link"}
