Using

Hydrostatic pressure relief valves are required to be installed in the floor or drain sump of  in-ground pools where the surrounding water table is above the base of the pool. An empty pool, even a concrete one, is like a ship, and it can be forced out of the ground by the pressure of the surrounding ground water.
