Hello, This is very unusual and we are sorry to hear of the trouble!
We do want to be sure that you were using this hose as designed, to manually vacuum your pool using this hose, a vacuum head and a telescopic pole? (It is not made for use with automatic (or robotic) pool cleaners. If you are using it for manual vacuuming we hope you have asked Home Depot directly for a replacement and are confident this will not happen again. Should you need any further assistance though please feel free to reach out to our Customer Service Department directly with all details at info@poolmaster.com - or call us, weekdays, 8-4 PST at 800-854-1492. We will appreciate the opportunity to make this right for you.
