I wasn't sure whether to put this thread in the plumbing forum or not. Seems to me that HVAC folks should
know how to deal with this issue. I went into the attic last night and followed the pvc pipe from the air handler
to what looks like an open 1 1/2" pipe starting at the floor of the attic going down the bathroom wall and probably
connecting to the vanity sink drain at some point. There appears to be a p-trap about 2 1/2 feet down from the attic
floor which would be about head height standing in the bathroom below. The drainage pipe I think is 3/4" diameter and sticking
about 18" down the drain pipe and I think the ptrap is about 2 1/2 feet down. The drip is very loud. We can hear it easily
in the living room.
So, that's the problem. I would think a good way to have set this up would be a slight bend above the ptrap like maybe 22 degrees,
then the trap , then reverse the 22 if necessary, but probably no need if set up that way to begin with. I don't want to cut into
the wall though. So, how to solve this problem? I thought of fashioning something flat just below the 3/4" pipe to divert the drips
to the side of the pipe, but it would have to fit fairly flush with the side of that 1 1/2" drain pipe in order not to just roll off the
end and again drip into the pool of water in the ptrap. I'm guessing there is some other clever way to fix this.
Making the problem possibly a little more difficult is that after that a/c drain was established, then the plumber ran the bath vent
pipe horizontally across the top of the horizontal a/c drain pipe in the attic to the roof. So, the a/c pipe cannot be pulled out completely
from the drain unless I cut it somewhere. Suggestions?
