My overflow drain exits out to the street curb. And waste (backwash, etc.) goes to the sewer line.
The pool has been at least 1" below the fill line so there should not be any water coming out of the overflow drain.
I contacted a pool guy I've used before. He stopped by and emailed that "It wasn’t leaking from the sight glass on high speed. I don’t think it’s bypassing to waste." That makes sense because any waste would go to the sewer line. But I still have no answer as to why water is coming out of the overflow drain when the pool level has been significantly below the fill line.
Any idea what could be causing this and what to try?
