HVAC – Handling Central Air Condensate Pumped into Basement Floor Hole

basementcondensatecondensationhvacsump

I’ve tried to do some research on this topic but am a little confused and would like to know if I’ve got a problem here that I need to remedy.

I think I want to install a self-draining dehumidifier in my basement. My only reason for doing this is the presence of efflorescence. Not sure if this helps that issue at all or if it will be a non-issue after I seal all the concrete, but I digress. Because I want a self-draining dehumidifier with no sink in the basement, I figured I could see where the AC condensate is being pumped and have the dehumidifier do the same, so I followed that line and found that it just empties the condensate into a hole in the floor. (Picture attached)

Some googling lead me to reading up on slumps but I’m really confused. This hole currently has water in it and I’m not sure how deep it goes. There’s no pump to pump it out of the house if it gets too high

Is this normal? Do I need to do something about it? Any and all advice would be greatly appreciated

It's just a typical floor drain, and it's the ideal place to drain your dehumidifier. What you see is the water trap, which prevents sewer gas from escaping. It presumably connects to your sanitary sewer, so be conscientious about what you dump into it.

Here's a modern drain just to illustrate the trap concept:
