So... the hot tub leaks out water... not sure how to address this.

The pumps all work, the heater works, the side panels have never been opened before.

Maybe in storage something dried up and has cracks?

Noticed it the first time we used it - then overnight, the water leaked out substantially to the point where I turned it off since the cycling feature came on with relatively little water in the tub.

Any ideas on where to start?
