First year with my 18' Intex Ultra Frame. All has been great, but today, came home to a leak, which seems to be on a seam near the bottom. I patched it from the inside where I think the leak is, with hopes that it actually worked. We'll see. Question is, how long is the warranty from Intex? Will they honor this? And how do I prove it to them? I got it at Walmart last year but didn't put it up until this year. I ordered it on July 22nd of last year, so I'm just under a year. Any suggestions on what to say when I call them?
