Sump Pump in Plenum

Curious if there is anything wrong with this: sump (condensate pump) embedded in concrete within the plenum of a air unit located in garage. Does this require removal, or repair?

Eric a sump pump in the plenum is always a problem water in the supply ducts=mold either the drain pan is shot and someone did not want to replace the pan and A-coil or there is ground water beneath the slab in either event repair/replace is called for

ridiculous situation and if plenum is flooding there is an indoor air quality problem in this home.

That is very dangerous! look up standing water and see what you find.
