HPI Single and Double Water Tubes for Winter Pool Cover

Our rugged heavy duty water tubes will not split like thinner 14- or 16-gauge bags. Up to 33% heavier than other bags. Quality Halkey Roberts no-leak valves are easily filled with a garden hose.

Put water tubes around the edge of the swimming pool on top of the winter pool cover. The maximum distance between each tube should be 1 foot. Additional tubes can be used for excessive windy areas. Place tube on the cover before filling with water. Fill each tube 3/4 full to allow for freeze expansion. To avoid leakage, do not drag filled tube across concrete deck or pick up filled tube.
