I must have accidentally drilled a small hole through the wall of the basement bathroom I was redoing right into the main PVC stack that drains all of the appliances form upstairs including the kitchen sink, upstairs bathroom, toilet etc. I can see where water is dripping/spraying out of the pinhead sized hole when toilet is flushed or dishwasher is used, etc.
I would like not to have to cut into the stackand replace that section of PVC pipe. What glue could I put in there to stop the leak, it would have to hold up under hot water temps?

Get a small piece of vinyl floor pan from HD or other supply store, clean the pipe, brush some PVC adhesive on the spot and make sure some goes into the hole, place the patch on the wet adhesive, hold it inplace for 2-3 minutes and it should be good to go. Another alternative is to get a small SS screw, coat the thread with 5 minute epoxy and run the screw into the hole. You could also get a Fernco fitting, open it up, slit the rubber sleeve, put the sleeve over the hole and tighten the fernco. Would look like a hubless fitting. SS screw is the easiest and would probably work well.

Thanks, but what is vinyl floor pan?

All great solutions by ma0641.
Let me offer another one. Small pinhole" correct?
When you glue two PVC fittings together the PVC Cement melts the surface of the PVC and welds them together. Here's what I would do.
Purchase a small can of PVC primer along with a small can of PVC cement.
Make sure the hole and area is dry, then prime around and into the hole. Pour PVC cement around and into the hole. Give it some time to set up and cure and no more hole. Good luck, Tom

My solution to your problem. It is cheap, fast and clean way to repair small hole in pipe...

1. Determine what size PVC pipe it is
2. Take that information and go to Home Depot
3. Buy coupling to fit that pipe
4. Buy PVC glue and primer
5. Cut coupling with hacksaw in half
6. Dry clean the pipe around the pin hole
7. Put one 1/2 of the coupling over the pipe and with the pin hole in the middle of the coupling.
8. Outline its edges with pencil, creating rectangular outline
9. First apply primer then ppply glue over on to the pipe and within the outline of the coupling
10. Apply primer and glue over the cut coupling
11. Press firmly 1/2 of the coupling over the pin hole and onto the pipe
12. Keep pressing for about 10 minutes until the glue sets

... and you are done repairing

Let me know how you did. Milo

Milo, Thanks, what would I do about the ridge that occurs inside cirumference of the coupling, it would create a gap?

[Milo Dolezal]

Sorry, I wasn't descriptive enough in my first response. Yes, of course, the ridge...

Cut the coupling right over the ridge. Ridge will be eliminated absorbing the width of the cut. Now you will have 2 rings ( narrow couplings ). You take one ring and cut it the other way. You will end up with two, U-shaped pieces.

If your coupling has 3 small "pegs" in the middle instead of continuous ridge than you can file them down.

We used this method many times in "tight" places with 100 % success. Sometimes we use 2 s.s. clamps to push that coupling tight around the pipe. We never remove the clamps and leave them installed around the pipe.

Hope that helps. Milo

I've used milo's trick more than once with good results.

Neat artwork hk.

Great solution by Milo.
What Milo has made is called a saddle clamp. But why go through the hassle of making one when you can buy one already made, (see image) check them out at: Water Leaks, Pipe Repair, Relining, Rusty Water, ACE DuraFlo's ePIPE
I still claim my first solution that I've always used is the simplest, fastest and most hassle free to patch a pin hole in PVC pipe. I've used it for years with no complaints. Good luck in whatever you decide, Tom

[ma0641]

You have a lot of good answers but vinyl floor pan material is thick PVC used to line the bottom of shower pans and other situations where you want to keep water from leaking through. I'll bet HD would give you a small piece, 2"X2" free.

I agree with Tom, although I'd probably put the clamp over it for my on physiological comfort, not because it is needed.

[delawaredog]

Yes yours sounded good too, but I still don't know what a small piece of vinyl floor pan is. Is this a piece of vinyl flooring or is there a pan that you prep your vinyl floor in before installing?

[Milo Dolezal]

Thanks Harold... that's the idea... unfortunately cannot rate your answer... Milo

[Milo Dolezal]

If I am not mistaken, the "Piece of Vinyl Flooring" is the vinyl liner used to water-proof shower pans with... correct ma0641 ?

[speedball1]

Yeah! Milo's correct. Walk into any plumbing shop and ask for a small piece of shower pan material.
However, I got to say I would go with Milos or my solution. One more time.
PVC cement melts the surface of two fittings and welds them together. By priming and gluing in and over the hole the opening will be fused together, I've used this method on both small cracks and holes in PVC drainage. Good luck, Tom

[ma0641]

My answer of 9/15 stands "vinyl floor pan material is thick PVC used to line the bottom of shower pans and other situations where you want to keep water from leaking through. I'll bet HD would give you a small piece, 2"X2" free". You can also line small ponds with it.

[delawaredog]

Thanks everyone, I used Milo's suggestion and so far so good! I will monitor it for a few days then close the wall back up.

[Milo Dolezal]

Are you sure that piece of PVC coupling sits flat over the pipe ?

[speedball1]

Thanks for the update. Good luck, Tom
