They need to be hosed down a couple of times, supposed to swell the threads in the sewing holes of the material. There should have been a small card in your info packet about it. We've had no leaks at all since the downpour when it did leak. Quite a bit of info in the forums about it. There's a sticky with a photo of the info card.
Hopefully there will be no more leaks from now on.
