I think technically your display in now the sump
As always i recommend you test the design by turning the pwer off waiting and turning it back on. To past the test there should be no floods and the system should return to normal when the power comes back on.
You do need to make sure the display is not filled and then overflowed during a power outage. The display will have to be empty enough to take the water that drains from the refug.
