This is a great little inexpensive way to cool off. I've bought these for several years and will continue to. I am VERY KNOWLEDGEABLE of how to fill the air ring NOT TO FULL CAPACITY. I set it up and had it blown up, soft and feeling underinflated, as is the desired result using a pump I have for an air mattress, and had it filled with water in a couple of hours. I was SOOOO happy to have a place to retreat on the following day as it has been a summer with record setting temps for an entire month.
The next morning, the ring was almost completely deflated, AND SO WAS I. I checked to see if the valve had opened unexpectedly. NO. I filled the ring again and went to work, late. I came home 8 hours later and it was deflated again. In the 92 degree heat, I doused the ring in soap water looking for a small pinhole. I covered it with Saran Wrap and looked for a hole. I thought about spraying the whole thing with FlexSeal out of desparation! Nothing. My husband came out as I was in a very frenzied state. In less then 5 minutes, he found the leak. The seam on the underside of the ring inside the pool was not fused in a tiny section. When he pressed the ring slightly into the water, blup blup blup blup. It took 3 attempts with an underwater patch kit to resolve it. I did not contact Intex as I was not draining the pool to send it back, if that was an option, and buying stock in the water company the following month. Please keep the installation CD and include an underwater patch kit instead. Please include an underwater patch kit in the box. Please include and underwater patch kit in the box. Some of us can and do read the instructions.
