We had the pool professionally leveled and put 3 inch blocks under the u shaped legs. The mistake I made was not putting the blocks horizontal with the bottom of the "U"; instead I put them vertical so the blocks would be centered in the middle of the 'U'. We had torrential rains last night and the pool filled up and buckled 6 U shaped legs on one side. Intex says these legs are out of stock. Anyone ever straighted bent U shaped legs successfully? So frustrated with myself, the rain and the pool!!! Thanks in advance.
