LOL, if there is a hole in the drain pan would that not be seen as going somewhere like the floor? My water drains into a PVC tube with the switch above it and this summer is putting out plenty of water that has to go somewhere and if not outside then backwards up towards the enclosed tube and switch. The pressure should be enough buoyancy force since it has no where else to go. Seems a pretty simple design.
