I bought the Intexpool 549x122cm 2005. Since it was used every summer. The pool body (except for the air ring) until today intact and without holes. We used the pool only in the garden shed stowed (Troken, but also in the winter time to -20 ° C. Now the air ring seems to dissolve slowly because apparently dissolved by the sun of the plasticizer from the pool ring and it turns ugly. Keeps air he unfortunately no longer. I am convinced of the quality of the swimming pool. Perhaps you have but also have a bit of luck, as some people so quickly already had holes in your pool. This included the Intex Cartridge filter is crap, we have noticed in the first year, and used a proper sand filter from the 2nd year. I think INTEX sold the filter only for the people where to buy the expensive filter cartridges - properly clean the pool so you can not keep. I want to buy a new Intex pool of the same size to me now, but can not find a listing that includes only the pool (without accessories). Well, I then soon offer a cartridge filter - please contact if interested.
