. . . IF the break in the pipe is above the water level in the pool,
AND the pool is ONLY source for water in that line,
AND there is no backflow or siphon from another location,
THEN the water flow will stop.
But I haven't seen your piping, the hole, or your pool . . . so I don't know any of that. And I've learned that customers and pool owners frequently omit critical information because they don't recognize it as critical, or sometimes for other reasons.

That's why I mentioned detailed photographs.
