Hey everyone, so I was installing one of those
wall anchors in the hallway closet, the ones that
go into drywall and expand once you place a screw
in it. Well as the subject says, I drilled a hole
into the vent running from the downstairs bathroom
up to the roof. What are the odds of that??
So, is there any problem with fumes, hazardous or not,
seeping out between the drywall?
I think the anchor and the screw plugged the hole.
Thanks for your time,
by modifying your home in this manner you have left the future of the
explosive fume exhaust system up to anyone with a screwdriver.
unless you are not speaking about a sewer vent line.
in any case the poor next guy will be asking us for help with a
mysterious source of odor or fumes from his hallway closet...
if you're not afraid of the methane produced by sewage that vents above
your roof, think about how nice it is when the system works properly
for a flammable liquid spill into the street sewer.
Well its a small hole, and its right up against the drywall and the
anchor is lodged in the hole. Perhaps I can jam a bunch of silicone
cocking in there to further plug it up.
I bet if the sewer vent was actually in the center between the drywall
that I wouldn't have this problem.
I'd just take an appropriate sized sheet metal screw, use a rubber
washer, dab some silicon on it and screw it into the hole. It'll hold
forever against the gases to prevent odor which is the only _real_
My vote for best answer is above. Only need to drill the sheetrock hole a
little bigger and will be easy to patch.
Just be happy it was ABS or PVC and not cast iron (though you probably
wouldn't have penetrated that so easily)
I think you've "cocked it up" enough already, Matt. :-)
Probably, but out of curiousity, how did you learn about your
unfortunate choice of spots to drill? Did you feel the resistance of the
pipe and seefind
If the anchor you used was one of those simple plastic ones that gets
expanded by a screw entering it, then I think you'd be fine if you just
removed the screw, pulled the anchor out, squirted in the silicone
sealer like you said and reset the anchor and screw.
Hahaha, good one Jeff :-) I got a good laugh out of that.
Honestly I didn't feel much of a resistance. I have one of those 18v
Dewalt drills and it cut right through it. I found out when I tried to
insert the anchor in and it had more resistance than the other anchor
I inserted. So I got one of those fiber optic attachment for my mini
Maglight and I was able to see some plastic but couldn't really make
out what it was, and then it hit me. Oh shit! I climbed up into the
attic and confirmed my suspicion.
The pvc piping that comes up from the wall in the closet doesn't go
straight to the roof. It actually hooks a 90 to meet up with another
vent and the pvc it self seems kinda flimsy. I guess it doesn't need
much since it just a vent.
I'll go ahead and seal that up with silicone and monitor it.
Thanks, take it easy,

Just take a utility knife and remove an inch circle of the drywall.
(after removing your anchor). Then plug the pipe with silicone caulk
or JB Weld. I would NOT leave it as it is now, you may get odors, and
worse yet, condensation builds up in vent pipes and will likely seep
out and cause your drywall to absorb moisture, causing mold and
deterioration of wall. Do it right, it's not that hard to spackle a
small hole after the repair.
PS. I'd use caulking and keep your "cocking" in your pants. A 3/16
hole is much too small for most cockings, and could be quite painful
if there was a sewer rat inside the pipe.... OUCH :)
A few years ago I drilled a 3/8" hole through my family room floor and
garage ceiling to run back speaker cables to the other side of the room. I
didn't realize I had drilled directly between the conductors of a run of 10
gauge romex until I started pulling the speaker wires through and hit a kink
in one of them which tore the romex insulation enough to short the
The fire was put out very quickly. Impressive sparkly light show, however.

Yeah, it would be nice to have the plans to the house, but KB
is being stingy due to fear of copy cats building companies.
I wish that it would just have where the plumbing and wiring
are laid out. I don't care about all the structural numbers
just some dimensions.
I hope it wasn't an expensive lesson learned.
Not too bad. The top paper of the ceiling drywall caught for a few seconds
but went out. I had to replace some insulation, patch the drywall and rerun
the electrical line to my AC Compressor. Unfortunately I lost about 10 years
off my life when the short made a loud bang, the lights went out and sparks
flew out of the hole for a few seconds.
