Water tubes are what the cover was designed to be held down with, since a tube that shifts cannot chip coping or tear a liner the way a brick, block, or paver can. Fill it to roughly three quarters, not to the cap, because the water inside expands when it freezes and a full tube splits. Buy enough to run the tubes end to end with no gaps.\u003c\/p\u003e\n\n  \u003csection class=\"swwts-spec-section\"\u003e\n    \u003cdiv class=\"swwts-spec-heading\"\u003eSpecifications\u003c\/div\u003e\n    \u003ctable class=\"swwts-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\u003e8' Single Chamber Water Tube, Blue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel \/ MPN\u003c\/th\u003e\n\u003ctd\u003eVWT8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003ePST-VWT8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConstruction\u003c\/th\u003e\n\u003ctd\u003eHeat sealed vinyl water bag\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClosure\u003c\/th\u003e\n\u003ctd\u003eScrew cap fill plug\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\u003ePlacement\u003c\/th\u003e\n\u003ctd\u003eEnd to end around the full perimeter of the cover\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\u003ctr\u003e\n\u003cth\u003eStorage\u003c\/th\u003e\n\u003ctd\u003eDrain fully, dry, and store flat out of sunlight\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003c\/tbody\u003e\n    \u003c\/table\u003e\n  \u003c\/section\u003e\n\n  \n  \u003csection class=\"swwts-faq\"\u003e\n    \u003cdiv class=\"swwts-spec-heading\"\u003eGood to Know\u003c\/div\u003e\n    \n    \u003cdiv class=\"swwts-faq-item\"\u003e\n      \u003cp class=\"swwts-faq-q\"\u003eHow full should I fill a water tube?\u003c\/p\u003e\n      \u003cp class=\"swwts-faq-a\"\u003eAbout \u003cstrong\u003ethree quarters\u003c\/strong\u003e.
