As I was trying to fill out the information to be able to make this review the pool I have doesn't pop up my pool I bought last year is a quickset designer pool 16x42 it's a great pool my three kids and two nieces enjoyed mid summer that's when we bought it. However the water caps (2) that you need to change filters got thrown away during set up, I called the company they said they would do a one time courtesy as long as I pay the shipping, which is wonderful however, there is a part number that I cannot find to get it replaced.
