This was back in 2014.
Another well known plumbing company recently replaced filters in my customers AC unit located in the ceiling of a closet.
After they left the drain vent would burp out water every time someone use the sink that the drain was connected to.
They came back twice with their best guys and could not figure out why.
Water does not flow up hill on it's own so why was water coming out of vent on condensate drain that was at least 6 ft higher than the connection to the sink drain.
PIC #1 AC condensate drain in closet ceiling.
PIC #2 Existing AC drain connection to sink.
PIC #3 My repair to the drain connection at sink.
