Water tubes hold an in-ground winter cover at the deck edge; they are not air pillows and should not be used to support a cover across the pool. The useful distinctions are length, single versus double chambers, vinyl gauge and valve design. Double tubes resist rolling and can still hold the cover if one chamber is punctured, while a single tube is simpler and lighter to handle. Every tube below is a current water-bag product explicitly sold for winter-cover use.

- blue
- Long double format covers straight runs efficiently
- Double chambers help keep the bag from rolling

Buying tips
- Fill water tubes only about half to two-thirds full so freezing water has room to expand; do not overfill them.
- Lay double tubes end-to-end around the cover perimeter and overlap them where a cover fits tightly.
- Drain, rinse and dry tubes before storage; keep a few spare bags and a vinyl patch kit for midwinter failures.
