Legacy Portable w/ Bowed Sides

[odddon]

Howdy group. We have a 13 x 25 Legacy portable pool that's been in place for 4 or 5 years, and the long sides are bowing out. It was just a little bit, which seems logical, but this year it is getting worse. Is this due to settling? One corner has dropped a few inches, and the opposite side is the one with the biggest bow. And more importantly, is this dangerous? I don't want 10,000 gallons of water rushing our house. And no, the ground around the sunken corner isn't wet, and there's no water loss, so I've ruled out a leak. Thanx!
