What is a hydrostatic valve?

What is the purpose of a hydrostatic valve on the bottom of a pool?

1) To relieve pressure and water from underneath a pool when it is empty

2) To relieve pressure and water from underneath a full pool

3) All of the above

4) None of the above (if so what is it for?)

Thank you.
