Patch hole in pvc dwv pipe

FastEddie | Posted in Construction Techniques on November 15, 2008 07:00am

Doing a little work on the ceiling in the kitchen, pulled off the crown moulding, then pulled a 10d finishing nail.  A little bit of water dribbled out of the hole, realized I was under the upstairs laundry room.  Did some exploration, found that the trim carpenter from 15 yrs ago tried to drive a nail and hit the nail plarte, so he moved over 2″ in the wrong direction and hit it harder.  I don’t think it is visible in the picture, but there is a dent on the left side where he first hit the plate.

Fortunately it’s a drain line, not a supply line.  So how do i permanently patch the hole?  Epoxy?

    Yeah, a screw and some glue. Drill the hole out to a uniform diameter, if necessary, and use a pan-head sheet metal screw (the shortest you can find), preferably stainless. Wrap with tape or a hose clamp for extra insurance.

    The other approach is to cut apart a plastic fitting of the appropriate size to get a C shaped piece of one hub, then glue that in place and fasten in place with a hose clamp.

      Dan, if he has enough room to wrap the pipe with your suggested materials, why would you not just replace the section of piping. Fix it properly or call someone who will.

      1. DanH | Nov 16, 2008 02:24am | #16

        Because it takes a lot more room to replace the pipe. And in replacing you introduce two new joints, not made under the best of conditions, and therefore introduce the chance of new leaks.

    Since it is a drain I'd NOT use a screw, esp as the hole is on the bottom of the pipe.

    The screw will catch hair, etc, leading to a possible future clog.

    I have 'fixed' pressure pipe with a small rubber patch and pvc cement held in place with a hose clamp.  Epoxy works well also, scratch up the pipe with sandpaper - probably need to remove that nail plate.

    1. FastEddie | Nov 16, 2008 12:08am | #7

      It's in the side of a vertical pipe, but I see your point.  The nail plate (there were two) are in the double top plate of the wall, the white textured surface is the ceiling, the stained material is on the wall.

    You could try just daubing some pvc cement on it and see if it fills the hole. 

    I'd daub on some pvc cement, and a small square of styrene plastic as a patch.  The pvc glue will melt both the styrene and the pvc.  It will be drip tight but not pressure tight, but that shouldn't be a problem. 

    The fail safe option would be a pvc sprinkler pipe repair kit.  It is a half piece of pipe, with an inside diameter that matches to od of the pipe to be repaired, some glue, and two stainless band clamps.  Any good irrigation supply place will have one.  PVC irrigation lines get dinged all the time, and it is lots easier to dig up a couple of feet and patch it than dig up enough line to flex it far enough to get a repair piece into place.

    Fast Eddie. I hate to be the bearer of bad news, but you can not permanently patch that pipe. Eventually sometime in the future, perhaps when another homeowner is in the house, your patch will let go, cause mould etc, and he will be yelling *&$%$/FastEddie. The only proper repair here is to cut out the old elbow above the top plate and somewhere in the wall cavity below. Glue in couplings and fish in a new elbow. Enjoy a little drywalling, mudding & taping, then rejoice in the fact that you have permanently repaired that pipe in a professional manner without ever having to suffer the slings & arrows of an Irate future homeowner, or yourself as you curse yourself out for not fixing it right the first time.

        Agree.

        I patched an AIR line ( the small copper tube from the comp to the on/off dohicky) with a small screw in a pin hole, and that was heating up and cooloing off and holding 120 psi.  It held for years, till the comp died.Spheramid Enterprises Architectural Woodworks

            It has absolutely nothing to do with pressure. You did not run sewage through your copper pipe and screw repair. Plastic and metal contract and expand at different rates and at different temperatures; the silicone adheres to each differently and with differing attachment to the surface profile of the materials. I have seen a life times worth of useless repairs to DWV and now I am sure that I will continue to see them. I am not disputing that your little fix held, but your compressor is not someone's house or the inside of a wall that might not be seen for 15 years now is it.

            Not tryin' to be a prick, but you may want to research, and put in some more time before you take the stance you are taking against the tried and proven.

            I aint jumpin' on the screw idea either 'cause I agree with Junk.., especially if there is any waste through the line. If it was a vent, I'd be singing Sphere's praises. But that don't mean you got all the answers either. Some problems with your solution also. I don't care enough to point them out.

    FastEddie. DIY's patch, and professionals do it the right way. I would never go into a clients home and patch this pipe. You have to repair the ceiling anyway, you have to repair the wall, the nailing plate is removable, would it not seem reasonable that replacing the section of pipe is really not that much more work. Most of the patches mentioned, except for the gobbed up screw, would take almost as long as a professional plumber to repair this pipe.

        Wasn't slagging you, I was implying that when someone asks a question they should be given the decency of a professional answer from a skilled tradesman. What you do in your home is up to you.

          Ok.  I'm a Journeyman Plumber.  I sit on the provincial trade advisory board.  I'm on the curriculum committee.   I'm leaving tomorrow for a week long workshop to develop national curriculum standards for plumbers and steamfitters-pipefitters.

          Professional enough for you?

           

          Clean with sandcloth.  Prime.  Apply heavy body pvc glue to fill the hole.  Repeat if needed.

          There are other accepted ways of patching.  Welding comes to mind.  If any of the guys that work with me cut open the wall and ceiling to fix that, he and I would be having words.   And I don't own the company.

          1. losh | Nov 16, 2008 03:55pm | #29

            Welding is an acceptable solution that I overlooked, but you can't possibly have never seen any failures in these home remedy patches? A screw with silicone? PVC glue, ABS Glue are designed to join two pieces of the same appropriate material together. The manufactures of these plastic glues do advertise heavy body as gap fillers, but I have always assumed that this was intended for gaps that may exist in saddle fittings etc, where a large surface area of glue is present, this is not the case in a hole. I have heard of people using ABS or PVC shavings in the glue to act as a filler but I've never personally seen it. As for the wall and ceiling, it was already opened up. I am not being snotty or trying to be ignorant with this question so hold the slings & arrows. How much longer would it take you to replace that section?Edited 11/16/2008 8:39 am ET by losh

            how about epoxy putty? That might work and would certainly be quick

          3. losh | Nov 16, 2008 09:29pm | #32

            Seen it fail too many times. As Rich1 posted, a plastic weld procedure should work, I've never seen the procedure done but usually a weld is stronger than the original material. But it is 'my opinion only' that replacement is better. Someone mentioned a fernco, which is also acceptable but if you have room for that you have room to properly replace the section of pipe.

          4. rich1 | Nov 17, 2008 05:13am | #41

             pvc glue is solvent with pvc dissolved in it.  It doesn't glue the pipe, it solvent welds it.  Melts the pipe together.  The dissolved pvc will fill a small hole.  Don't trust it, use pvc welding rod to fill the hole.

            Better yet, use a matching plug and hole cutter and make a plug, glue it in.

          5. atrident | Nov 17, 2008 05:29am | #42

            PVC welding rod.You must be kidding. The fix I suggested is good for 125psi and its a drain.....zero pressure. 

              OK ..If you want to get real tricky cut the coupling 60% 40% lengthwise. sand down the angle on 60% piece. This will snap over the pipe and self clamp. Use band clamps if you feel like it but they are not necessary.

Prime and glue it in place.<<<Hose clamps and self-vulcanizing tape and I can guarantee that to at least 60psi as I have repaired 2"PVC water lines this way numerous times.If you cut the wall to cut out the pipe you are still going to add one poor connection whether its a Fernco or compression fitting in order to get it back together.We have installed miles of 10" PVC to serve irrigation systems on the ranch and I can tell you that a decent fix is ALWAYS better than digging up 20' of pipe and using two dressler couplers at $100 each to fix a small hole or seep in the pipe.But I am not a professional plumber, doing only ONE thing in life would be too boring...

      1. DanH | Nov 17, 2008 04:53am | #40

        I think atrident was referring to cutting a hub apart lengthwise, to get a C-shaped piece to glue over the hole. Should work fine, especially if clamped in place with a hose clamp.

          I guess I didn't quote that too well -I was in 100% agreement with his method + the hose clamps to keep the coupler in place while the glue dries and tape for extra protection from an errant drip -I hate this forum software BTW, thanks for catching that one.

            Check out my edit. That way you dont need the clamps. There are saddle tees made like that  so I cant take credit for the idea.
