Vanishing Edge Water Basin

I have a vanishing edge pool, three different water basins. The one basin that the spa runs off of continues to over flow while running and I just can’t figure out why...
Tried uploading video but it’s too large of a file...

You need to put videos on YouTube or Vimeo or other video host and link to it.

If the basin is overflowing it means the water in is greater than the water out. Did it ever work properly? Were any pumps replaced? What is the history?

It's getting water from somewhere if it overflows when it isn't supposed to. Maybe a check valve is not sealing properly or a valve is tweaked a little bit off-center?

I had the hinge break on a check valve flap and it drove me batty trying to find where the issue was when my spa would occasionally drain for no obvious reason - everything looked fine through the clear top of the valve. I only found it when i took it apart.
