Designed for seasonal pool closing, each tube has a leak-resistant valve sized for easy filling with a garden hose. Fill each tube roughly half full to leave room for ice expansion and reduce the chance of splitting.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these water tubes keep my cover in place?\u003c\/h3\u003e\n\u003cp\u003eThe tubes act as ballast, resting along the perimeter and pressing the cover flat against the deck, which helps block wind and keeps the cover from sagging into the water.
