I get a bad smell in my hallway near the AC unit when I run the faucet
in the kitchen. I've posted about it on this group before and have
gotten suggestions that it's a problem with the vent pipe.
I bring the plumber in and it takes a while but I finally convince him
about the smell (of course the few times I've gotten them in the smell
doesn't appear), and he tells me that it's possible that the AC drain
line leads into the sewage lines; but it's illegal for it to do it. So
he says what they can do is open up the walls and run a line to the
outside of the building and let it drain through that. It looks like
they'll have to open up a sizeable chunk of wall to do that
Before I commit to the time, expense, frustration, and risk that this
will cause I wanted to see if anyone saw any other solutions? I mean,
I guess it needs to drain but is there any other way to do that?
