I never could find the leak, so I drained pool, bought a new liner, filled up, and still leaks! I would figure the odds of a new leaking liner is low (maybe a bad assumption), so if it's not that I figure it must be the inlets/outlets, but I see absolutely zero water leaking out of the inlets/outlets. Ground is dry everywhere. Is it possible to leak out of inlets/outlets without being able to see water? It's just past the inlet now. Waiting to see if it goes past outlets. So frustrating.
