The water is coming from the top of the leaking section. I don't see any of the blue cement the installers put on the other sections. What could this be caused from? Is there an easy fix?

maybe they forgot to glue it check to see if that leaking connection comes apart if it does turn off the pump that pumps the condisation out and glue it with pvc medium bodied glue and put together hold it for like thirty seconds them its good to go turn the pump back on and check for more leaks . unless they did not seal the opening where the pipe goes outside and the moistor or rain water is traveling in throw there
