Water Tubes will keep the cover from sinking into the inground swimming pool. Tubes should ideally be touching each other end to end (around the pool). The Standard Duty Tubes are made of 16 gauge vinyl. They will not split, rip, puncture or break.
Installation is easy! Simply fill to 50% capacity (to allow for expansion of ice) with a garden hose and close the leak-proof valve.
Minimum purchase of 4 required. Quantity discount applies.
