I think I put a lag screw into a vent pipe.


My wife said the bathroom smells like poop. Sure, enough it did. You could smell a slight sewer smell from an area where I removed a baseboard to install a cabinet. Then I got to to thinking, "did I screw that left lag bolt into the vent pipe?" Well, I think I did, because up in the attic, the vent pipe comes out of the 2 x 4 header about 10" away from where I screwed it in. I am guessing the vent pipe angles up the wall to move around a larger support beam. When I unscrewed the screw, it didn't have a pine smell on the end of it like the other screw.

How can I best fix this blunder?

Plumbers epoxy? I also read that you can screw in a stainless screw with silicone on it, but I'm kind of leaning towards not doing this.... This is a good size screw, about 3/8 in diameter.

Thanks for any help.

I'd probably use some epoxy such as JB weld or similar, scuffing the surface of the pipe with some coarse sandpaper to make sure to get a good bonding, and making the repair bigger than the hole.

After the work needed to get access to the pipe so you can really check it...
the best fix option will depend on the material.
Is the vent pipe Cast, Steel or PVC?

It is PVC.

I was planning on cutting out a 4" x 4" piece of drywall and go from there.

One sure way to seal it would be to take a short piece of 4" PVC about 4"" long, cut it cross ways so a 1/3 section is left, apply primer and glue and stick it over the hole.
Another short Stainless steel lag with silicone on it may or may not work, The pipe is round and the back side of the lag is not.

I hear JB Weld is solid as a rock.

Using this seems more than sufficient, I would think.

Isn't JB weld just for metal??


I'm really asking, not trying to be a smart-a$$ ....that's unlike me to NOT be a smart-a$$, but I have my moments.

I like this method, but use a large pipe clamp or two instead of screws - the screws may catch "stuff" -

Not sure, but I think this part of his answer was referring to the OP's idea in the 1st post.


I also would go with hose clamps vs. screws if it was me.

No screws needed. Just glue the patch as joe said. The glue will hold it

Their website specifically lists PVC as an application. Seems like this hard and strong epoxy would work perfectly in this case. After all, the vent pipe is only holding gases!

Was the screw removed? If not, and it's just a vent pipe.....then the screw is sealing the hole unless the pipe cracked. I would not expect any smell to come out unless the screw was removed.

You might have something else wrong.

Oh great. I was wondering how that could cause an issue. I hope it's not cracked. I guess I will be able to tell once in there if it was indeed a vent pipe I went into.

The only other things that changed in this bathroom remodel were

1. New toilet installed. Not sure how I could have screwed this up since it is caulked in good and of course a new wax seal that came with the Kohler toilet was used.
2. About 2.5 feet of baseboard was removed so that the new vanity would sit flush with the wall. So behind the vanity's legs the concrete slab is exposed beneath the end of the drywall. There is obviously a drain pipe in this area also where the hot and cold supply valves are located.

I guess it's possible that there was some kind of leak before hand. I can't feel any moisture where the exposed slab is at all.

The smell is not super bad, it seems like it comes and goes and is not totally repulsive. The few times I had noticed it, I figured I was smelling someone's residual poop smells.

Thoughts?

What else could be wrong? Could it be a busted sewer pipe in the slab? Wouldn't that be pretty obvious?

An inspection of the vent pipe in the attic yields no odor as far as I can tell.

You caulked in a toilet?...hmmm. I was told to never caulk a toilet.

Yes, of course I caulked the bottom of the toilet. We set it and then caulked the bottom to the tile.

Standard practice I thought, at least in the 3 houses I have lived in and 100's of other people's houses I have been in.

**edit** I just read that you should leave a small area uncaulked around the back just in case of a leak. I will remove some of the caulk from the back tonight.
