Query: piece of crap

this thing is basically trash. i bought one last summer used it for july and august then stored it in my house away from any cold weather elements. i pull it out this summer and of course it leaks water comes down the back and sides everyday i have to add water to it (lots of water) i got screwed this thing is worth about $50 to me it seems like something you would buy at walmart on clearence after the summer.
