Keep the pool filled through the winter. In areas that freeze, lower the water to about 6 in below the lowest skimmer opening, then hold that level steady. Snow and ice on a winter cover need the water underneath for support, and the pool should never be left standing empty.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \n  \u003c\/section\u003e\n  \n\n  \u003csection class=\"bwtrinity-cta\"\u003e\n    \u003ch2\u003eBuild Your Trinity Pool With PST\u003c\/h2\u003e\n    \u003cp\u003eReal pool people on support, fast answers before and after you buy.\u003c\/p\u003e\n    \u003cdiv class=\"bwtrinity-perks\"\u003e\n      \u003cspan class=\"bwtrinity-perk\"\u003eFree Shipping\u003c\/span\u003e\u003cspan class=\"bwtrinity-perk\"\u003e30-Day Returns\u003c\/span\u003e\u003cspan class=\"bwtrinity-perk\"\u003e30-Year Warranty\u003c\/span\u003e\u003cspan class=\"bwtrinity-perk\"\u003eAuthorized Blue Wave Dealer\u003c\/span\u003e\n    \u003c\/div\u003e\n  \u003c\/section\u003e\n\n\u003c\/div\u003e\n","brand":"Blue Wave","offers":[{"title":"Default Title","offer_id":44619564023873,"sku":"PST-NB1851","price":5145.9,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/1623\/0209\/files\/acazvkux7rbaprehinxf_1e06c93a-69da-41e6-9aca-24330041f0a1.jpg?v=1789676116","url":"https:\/\/www.pstpoolsupplies.com\/products\/trinity-33x18ft-oval-52in","provider":"PST Pool Supplies","version":"1.0","type":"link"}
