In my continuing effort to inspect (and fix where necessary) the work of the previous homeowner's plumbing - I came across this in the crawl space.
The HVAC unit is in the attic and the primary condensation line runs through the wall and end up in the crawl space. As you can see in the attached picture, there is a trap coming off of the main stack and the condensation line runs directly into it.
So, the questions are:
1. From what I've read, I would think at a minimum there needs to be an air gap between the two right? How big of a gap should there be? Shouldn't there be a flared end (not sure of the technical term) on the top of the pipe running vertically from the trap?
2. Is the trap and the way it connects to the stack done correctly?
Thanks for any help in advance!
