I have a leak in the drain line from one of the upstairs bathrooms in
a wall in the kitchen. Without opening the wall, my guess is that the
screw that holds the wire shelves in the kitchen was put where it
shouldn't have been. Is there an easy way to repair a hole (#8 screw,
perhaps) in PVC pipe? If this is the issue, a small hole and a repair
isn't going to be a real big deal. If I have to cut a section of pipe
out and fit new it may be. The pipe goes into the concrete slab about
2' below where I think the leak is. Thanks.
If you don't want any protrusions in the drain line from a screw, you
can remove the screw, cut out a segment of PVC from a new fitting to
match the outer radius of the pipe, and glue it on with standard PVC
glue after priming it.
If indeed a screw did penetrate the pipe, it should not leak. I
understand if you removed the screw then it would leak.
But if you can gain access, just plug the hole with epoxy or pvc
But you wont know whats going on unless you remove the sheetrock.
Is this the main stack coming down? How big is the pipe?
Not so fast. A screw driven in with a drill could easily spin enough
to strip out material and allow for a leak. And PVC has been known to
crack from getting fairly minor, but unlucky, hits. A screw driving
thru some wood might push enough force on the screw tip to start a
Some exploration is in order.

One of them. It's a new house, so I assume it's a 4" stack. I'll
open it up this weekend, perhaps. We don't use that bathroom (so
never noticed the leak) but the kid and DIL are coming to visit next
Keep the wall damage minimum (smaller patch). The link here shows a
simple hose clamp and rubber. * I would try stainless hose clamps and
rubber, depending on what you see in the wall.
The builder had to come back and fix a stack years ago. Every Monday
morning the downstairs carpet would be soggy wet at one corner. There
was a pattern - SWMBO bathed on Sunday night and tub drained from the
A rubber sleeve / clamp connection was not installed properly so water
leaked out the sleeve. Locating the pipe caused numerous wall repairs.
The builder did a wonderful job.
Please post back what you find and your solution. Folks like to hear
Thanks, that's sorta what I was thinking about doing. I just wanted
to get other's ideas before I open the wall. The wall in question is
between the refrigerator and a pantry (a closet, really) so I can open
either side of the wall.
Damned builders <mutter>
If you are sure it is the screw...
Remove the offending screw and go to either Wendy's or McDonalds for
lunch, not Burger King. Get an extra straw.
Enjoy your trans-fat laden lunch.
Drill a 1/4 hole in the wall where the screw used to be
Cut a sliver off of the tip of you tube of caulk
Put your extra straw over the end of the caulk and insert the straw
throught the hole in the wall until you touch the pipe with it
Squeeze your caulk through the straw and onto the pipe (hold the straw
tightly it will want to come of the caulking tip)
Put a little more caulk in the hole in the drywall on your way out and
smooth it over
When the caulk dries hit the hole with a light coat of spackle
(Burger King straws are a smaller diameter and won't fit over the tip
of the caulk tube)
If it's really just a screw hole, dab a little pvc cement (even that partially
dried old can) onto the hole. Let it dry. If any hole remains, dab a little more
on. Repeat as necessary.
My father had a leak in the drain pipe in the basement under his kitchen sink.
When I found the drywall nail through the pipe under the sink, I thought we had
it. Turned out, every section of pipe down to the basement floor had a split
down it. Best guess - someone drive over a length of pipe lengthwise, then used
it to plumb the house. Who knows??
dont know if you fixed it yet but i repaired a pvc waste pipe that was
leaking at one of the glue joints with elmers epoxy glue, the bottle
has a blue bull on it. it dries hard as a rock never cracked or
leaked.. been 2 and half years now.
