Heavier vinyl matters on stone, brick, and broom finished concrete, where a thin tube abrades through in a season or two. The double chamber build keeps half the water in place if one side gets punctured, so the cover edge stays pinned. Fill each chamber about three quarters full so freezing water has room to expand.\u003c\/p\u003e\n\n  \u003csection class=\"swwthd-spec-section\"\u003e\n    \u003cdiv class=\"swwthd-spec-heading\"\u003eSpecifications\u003c\/div\u003e\n    \u003ctable class=\"swwthd-spec-table\"\u003e\n      \u003ctbody\u003e\n        \u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eSwimline\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct\u003c\/th\u003e\n\u003ctd\u003e10' Double Chamber Water Tube, Blue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel \/ MPN\u003c\/th\u003e\n\u003ctd\u003eVWT10D20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003ePST-VWT10D20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGrade\u003c\/th\u003e\n\u003ctd\u003eHeavy duty, thicker wall than the standard tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eDouble chamber vinyl, heat sealed seams\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClosure\u003c\/th\u003e\n\u003ctd\u003eScrew cap fill plug on each chamber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFill Level\u003c\/th\u003e\n\u003ctd\u003eAbout 75 percent, leave room for ice expansion\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUse\u003c\/th\u003e\n\u003ctd\u003eWeighting solid winter covers on in ground pools\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBest For\u003c\/th\u003e\n\u003ctd\u003eRough coping, stone decks, and hard freeze regions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSeason\u003c\/th\u003e\n\u003ctd\u003eFall closing through spring opening\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003c\/tbody\u003e\n    \u003c\/table\u003e\n  \u003c\/section\u003e\n\n  \n  \u003csection class=\"swwthd-faq\"\u003e\n    \u003cdiv class=\"swwthd-spec-heading\"\u003eGood to Know\u003c\/div\u003e\n    \n    \u003cdiv class=\"swwthd-faq-item\"\u003e\n      \u003cp class=\"swwthd-faq-q\"\u003eIs the heavy duty tube worth the extra cost?\u003c\/p\u003e\n      \u003cp class=\"swwthd-faq-a\"\u003eIf your deck is stone, brick, or rough concrete, yes.
