Perhaps the warranty only covers the pool for leaking. This pool might not be leaking.
I've been looking at pool companies lately. I will probably get one for my new home. JD pools has a 15 year warranty on thier fiberglass pools and a 10 year warranty on their liner pools. "15 year structural warranty, strong, flexible and leak-free". I'd say the pool in the article meets the 'flexible' part of the warranty.
Anyway it would be nice to know which companies to avoid.
