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). 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.
I bought these to replace some of the standard ones that have faded and sprung leaks the past few years. The quality is noticable with the heavier duty water tubes. The customer service agent I spoke to when confirming inventory was helpful and friendly. I like doing business with EZ Test Supplies. Thank you.
