Te top ring I have to refill with air every day.I looked and cannot find a leak. I know it expands in hot weather and contracts at cooler weather but that is not the problem.I have bought about 5 Intex pools over the years and I am dissappointed in the quality of this top ring. One night I lost about 1500 gallons of water after the ring came down. The ladder and pump seem good but I feel the quality of the pool needs to be upgraded. Now I have to add air every day and worry about wearing out the air intake lock wearing out.
