Hi Everyone. I am looking to add a second sink to my kid's double vanity that currently only has one sink (stupid decision not to just pay for it while the house was being built, I know).
Anyway, here are some pics I took while the house was being built. I believe I have a single 1.5” ABS drain.
From the other “adding second sink” threads that I found searching this forum I need to add a drain/vent like the pic below. Does this look correct? (hard to read some of the notes but the horizontal vent needs to be at least 42" from the floor?)
However, in the spirit of trying to cut the smallest hole in the drywall as possible can I also do it like the picture below – where I run the vent for the second sink straight up to the attic and tie in to the horizontal run in the attic where the existing sink vent goes. Going this route would ideally allow me to just drop in the vent from the attic above thus limiting how large a hole I cut in the drywall (ideally the cut would be lower than the vanity so I don’t have to perfectly patch drywall).
Pic of the existing sink vent in the attic. I think I would need to tie into it somewhere around the area where the vent goes out of the picture. Would that be ok?
Any thoughts or insights would be GREATLY appreciated! Thanks!
