Plumbing/AC/Code/Sewer gas smell question - Bet you weren't expecting that combo, now were you?
A week or so ago our condenser was replaced due to a leak. Since then, we've had a sewer gas smell in the house. One possibility I uncovered while reading on the subject is that our A/C condensate line drain runs down and ties into a sink drain, but on the back side of the trap. In other words, the drain is open to the sewer line.
The new condenser was a different configuration than the last one. I'm thinking that the smell is coming from sewer gas being sucked into the system from the drain.
Am I correct in thinking that their should be a trap in this line? Also, should the installer have removed the knock out to allow water to drain into the emergency pan? I thought this guy knew what he was doing, but now I'm wondering.
