Plumbing question about pipe
+5
Some time ago when my remodel was done, unbeknownest to anyone, one of the kitchen cabinet screws went into a wet plumbing vent pipe. The cabinet company has been great and going to fix everything. 3" vent pipe (one end to the roof the other into the concrete to drain to the sewer) and the guest bath does flow into it (with 2 sinks, toilet and shower). The plumber proposes to cut out the compromised pipe but not sure can slide/glue in a solid plastic pipe in the tight space. So proposes a neoprene sleeve on one end. This will then be buried in the wall between the kitchen and garage and foam insulation sprayed in. I am a little concerned about the sleeve but I know they are common when connecting to some iron pipe with other metals or plastic. Is this a good idea? Better ideas? I have been assured not a code issue.
Leaking pipe....the drywall will all be replaced.

I've used the neoprene sleeves before. No problem for a vent pipe. Main thing your doing is sealing off the gas. Now if other drains above drain in to the vent, could be an issue, but probably not.

Yes this type of sleeve is used alot when connecting PVC to iron. In those cases it a bit tough as often the iron has had some corrosion and the OD of the pipe is not perfectly smooth and poses some leakage potential. with the smooth OD of PVC you should be golden.

We use rubber couplings all the time. Not an issue at all. These are made just for this type of issue.

ent pipe... no pressure... sleeve... JUST FINE! Yes, I have a story for a somewhat similar situation too. Three houses ago, my Lovely hung a picture. I was at my office in North Atlanta. She calls and says... "One of the two holes was harder than the other to drill, but it should be OK cause the screw held, About a half hour later, she calls again. The picture is still up but it's leaking. Yup, right into a drain pipe... I think that was my most interesting home repair event. I made a PVC plug into a sort of cone shape and tapped it into the drain pipe with PVC cement. It held well! I sold the house to some friends, they've lived there now six years and it's still holding!

Kevin, Since I concur with all the input thus far, just a bit of trivia. One of the major manufacturers of these "rubber" couplings is Fernco...many of the plumbing pros refer to them as a fernco... very similiar to the common use of "Kleenex", which is a brand name as opposed to "tissue". Tim

Thanks all! I was concerned about burying in the wall since it is a wet vent pipe.

I worked at a plumbing company for 31 years. These neoprene sleeves are even used underground. You'll have no problem. They're great.

I realize this question is long since past the point of me even replying BUT that didn't stop me from adding my 3-cents worth!......lolol.....check with the building code requirements...just to be safe. Pretty sure that patch would not pass in Canada BUT south of the 49th. parallel the "rules" change.
