Hello all - I'm hoping you can help me with a diagnosis on our hot tub leak. We've got an in-ground, gunite hot tub circa 1975, maybe 500 gallons. The hot tub has almost drained itself entirely in less than 3 days, with no pumps on. There is a drain in the bottom - could it be pulling water out even without the pumps (circulation and jets) off? There is exposed piping with little holes drilled in it (these release air bubbles when we have the equipment on. I thought it would drain to the level the leak is at, but it seems intent on completely draining itself.
Attempting to attach a photo a few ways, have never done that before... it's lost almost all water since filling on Sunday afternoon. (that's the hose, draped across it).

Thanks for any insights you all can provide!
