Boulder 24' X 48 inch ATS Easy-Build Steel Above Ground Swimming Pool Kit by WaterThat (WTECH2448)

I had the pool professionally installed. I’ve had it for about a month and the liner has already sprung a leak. I do not going to the pool with any sharp objects. No stones underneath the liner only soft floats inside the pool nobody has long fingernails or toenails. There’s just really no explanation as to why it’s leaking. I will have to spend more money to have professionally fixed, or the liner completely changed, depending upon what the contractor says
