It seals the strainer pot, the chamber where the pump basket catches debris before it reaches the impeller.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy lids fail\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe pump lid is the most handled part on the equipment pad. It comes off every time the basket is emptied, it sits in direct sun, and it takes chlorinated water and sanitizer splash. Over a few seasons the plastic crazes and clouds, and eventually a hairline crack or a distorted rim appears. From that point the lid no longer seals, the pump draws air on the suction side, and it stops holding prime.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReplace the lid o-ring at the same time. A new lid pressed onto a flattened, hardened o-ring will still leak air. Lubricate the o-ring, set the lid down square, and hand tighten only. Overtightening is the single most common cause of the next cracked lid.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48634376028372,"sku":"PAC-101-3074","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_533ffdea-1178-4fa5-8ea0-cd9f3adf3487.jpg?v=1788828752","url":"https:\/\/www.activepoolsupply.com\/products\/clear-plastic-lid-590","provider":"Active Pool Supply","version":"1.0","type":"link"}
