Hi y'all,
Here is my issue;
Upstairs sink not draining. Pulled P-trap and hand snaked the line. P- trap was plugged up where A/C evaporative line feeds in. Cleaned it out, good as new. Reassembled P-trap sink still backs up. Noted that when toilet flushes I can hear it in the tub drain. Tub drains fine though? Is my problem vent related? I also noted that the wall was wet where the vent pipe comes into the bathroom wall from attic. So I went into attic and observed the ceiling area where vent pipe enters wall was moist. There is an elbow joint of sorts where the vent pipe enters the wall. Is it possible to back up the sink water into the vent pipe? Why else would the vent pipe appear to be leaking water? I have read that a "gurgling" sound from the tub drain (sounds like the toilet flush echoing in tub drain) is a vent issue. What say you?
Thanks!!

the a/c CONDENSATE line can get COLD and may sweat externally

That thought had crossed my mind, however it is the vent pipe that has the leaking issue. Is it possible for water to
Back up in the vent pipe? Also, why can't I get my sink to drain? The two are related somehow. Plus the toilet flush echoing in the tub drain I think is also points to the vent does it not? I'm thinking the constant a/c draining into the backed up sink drain may have somehow backed up into the vent? Is that even possible?

somewhat possible - but NOT above the flood level of the fixture(s) served by said vent
(water seeks its own level)
however, the pipe should NOT leak - period
this is why it is best practice (not necessarily code) to INDIVIDUALLY vent each fixture
sounds like you need a plumber 'on site' to assess and clear your stoppage
AND repair the vent
a/c condensate lines 'often' have issues with algae formation which 'could' create a stoppage in seldom used fixture drains
to repeat: you need on site assistance
I, from my home, am merely guessing.
