Uh Oh, What the Studfinder Missed - Plumbing Tips Anyone?

Just use this stuff and call it done: http://www.plast-aid.com/index.html .  This happens all the time in new construction, my plumber used this and then runs the pressure test just fine.  Never a blink from the inspector.  Not a bodge job.  Plastic welds.  no one would accuse a metalworker of a bodege by welding a repair onto an existing piece metal- same difference.
 
Id split a coupler and weld it on. Would be no different that a strap on boss welded to the pipe
 
I've already posted my response but then just now I have a rather strange thought.  If this is a repeat of something else here please just chalk it up to Super Bowl syndrome.  Hoe about drilling out the holes with a larger drill bit and then using a tapered plug cutter to make matching plugs.  Using the proper cement glue and tap them in.

Just a thought.
 
If it was me, I'd stick a tampon in the holes...Nothing seems to be able to plug up the sewer lines good and tight like those little white mice!
 
*Update*  So yahoo, it's time for drywall.

I decided to hire out the plumbing for cheap insurance.  I debated using epoxy and I'm glad I didn't.  Once we cut out the bad section we looked up in the 3" pipe and noticed 18 gauge brad nails coming into the pipe from the other side.  Turns out, whoever installed the pantry shelves when the house was built shot brad nails into the pipe from the other side in a few places.  There were some mighty rusty brads sitting in the pipe.  For the time being, it was doing a good job plugging the holes.  In time with the rust, I'm certain there would have been some minor leaking.

Glad to catch it, so we cut a much bigger section of pipe out as a permanent fix.

Now I will just have to add a little plumbers tape, and enjoy some drywall repair before I can install the desk.  Oh joy :)

While the wall is open wrap some insulation around the pipe.  It will help with sound being its pvc and not cast iron.

I am guessing that is the *expensive* insurance!  The cheap insurance would have been cutting a union in half and gluing it on or just driving some stainless steel screws in, etc

At least it is fixed and you can move on....  Just curious, how much does  plumber charge for something like that?
 
Good news, especially with the additional brad nails in the upper section. Smart to "do it right" and depending on the amount of action the pipe will handle while your surfing, the extra insul may be useful.
 
Grasshopper,
That's a real load off your mind!  I'm glad it turned out the way it did.  Now it's time to finish up!

good call

My first introduction to the building trades was at about 14.  A neighbor who was a plumber was also built like the typical cartoon plumber.  He had a job removing ancient black and galvanized pipe and replacing with copper tubing.  This was back around mid 40's right after WW II had ended.  Much of the work was to be performed in a very tight crawlspace, and I had learned how to solder in HS shop class.  I was "volunteered" for the job in the crawlspace as I was barely over 100 #'s wringing wet if my boots were full of water.  I am claustrophobic; but was able to keep my problems with tight spaces under control by fighting thru cobwebs and my interest in the plumbing problems at hand.  The old pipes had to be cut and dragged out into the cellar area.  The new pipes had to be measured, dragged back in and sweat together.  All of that seemed to be far more interesting than my horrors a being compressed into the narrow space.  That space was so tight that each time i slid my way into the work space, i had to determine whether i had to work lying on my stomach, or lying on my back.  I could not turn my shoulders without going into panic mode.  I spent most of my one week vacation from school that spring fighting cobwebs, dust and claustrophobia, but i learned a lot about plumbing.  The main thing I learned was that i was not very interested in working insight spaces full of spiders.  The installation part was interesting.  Otherwise, i could not have lasted.

Fast forward:  When i came out of the army, i worked for a short time with the same plumber.  By that time, he was well on the way to a very liquid diet and would leave my on the job alone while he went supposedly for materials. the main materials quite often required that i get hold of a buddy and the two of us would make the rounds of the plumber's "materials suppliers", load him into his car and my buddy would drive the plumber's car and I mine.  We would deliver him to his home and i would do the bookkeeping for the days work i had done as well as keeping track of the actual plumbing materials used.  I learned a lot about plumbing during the month or two I worked with the man.  Eventually, he did straighten himself out and we remained friends until he moved away.

Faster forwarder:  eventually, my wife and i moved into a house in Ridgefield. We were on a local water system where the water was so hard (lime) you could cut it with my stone chisels.  It was not long before a valve in the system sprang a leak.  since i was a "very experienced" plumber, i confidently set to work making the repair.  By the time i was able to break the fitting loose, i had broken a section of rotted pipe.  fixing that led to a broken rotted fitting somewhere else.  What should have taken me no more than an hour, tops, ended up taking the better part of a day with several trips to the supply house in the bargain.

The next time we had a valve leak, the same sort of scenario.  AND, the next time, I got smart.  As the old German mason who had been a mentor back in my pre army days had said, "So soon vee grrow oldt, so late schmardt." I called a plumber friend.  I have never touched a wrench to a plumbing problem since.  I don't really care what he charges, it is great insurance.  [smile]

What starts out as a simple "install a desk" turns into a plumbing nightmare. Home ownership is never dull. :)
 
Tell me about it!  I've got a downed tree in my back yard that I haven't had time to cut up and haul away as I have been to busy trying to make the inside look nice.

All part of life i suppose.  I installed the drywall yesterday, 2nd coat of mud coming now.

Being a plumber I would have done 1 of 2 things. Plastipoxy, stuff works like a charm. or 2 silicone it and take one of those aforementioned furnco couplings and sliced it down 1 side. and put it over the silicone with the slice on the opposite side.
 
I'm glad you found all the holes and got them fixed.  I am also glad to see a plumber recommend something similar to what I did once.

In our Pittsburgh PA house >20 years ago, I made all new kitchen cabinets (3/4 oak plywood boxes, 3/4 raised panel Oak doors) one at a time - or a run at a time - and installed them as I went.  My late wife was tolerant and like the new cabinets.  When I removed a large cabinet where we put all our everyday dishes, I found it had been hung on the plastic waste stack from the upstairs bathrooms.  The drywall was moldy and the screws had rusted off.  We'd had probably close to 100 lbs of dishes in that cabinet and it was held to the wall by only one screw in a stud.  I removed all the moldy wall board - fortunately it didn't extend out past the edge of the cabinet.  Then I cleaned the area of the pipe with a hole, used a drill bit to clean up the hole by making it very slightly larger, and put a dab of silicone caulk over the hole and hung the new cabinet.  It never gave us any trouble. 

But in my case there were no nails in the pipe at another elevation.

It surprises me a little when experienced woodworkers won't do plumbing in plastic pipe.  Normal woodworking tools work fine.  With couplers, that was an easy job.  You can also buy plastic couplers without the ridge in the center so you can slide them up (or down) on the pipe so it doesn't have to go up and down.  goop it up with glue, slide into position and permanent repair made.  I will soon redo 3 bathrooms, one at a time.  I've put in 3 so far in other houses.  Soldering copper slows things down but isn't hard.  Here they use CPVC supply lines and with plastic supply and drains, it goes pretty fast.  A CMS is nice for cutting the pipe but a handsaw or reciprocating saw works fine.  Plumbers even cut small ones with special scissors type devices. 

I hope you got a fair price.  I had a neighbor get charged $400 to reattach a hose bib.  And the job was done poorly and had to be redone.  It was about $5 in parts and half an hour to do it.  I saw him having an issue but was busy and didn't go over.  I was sad later when I heard what happened.  I helped him on the next plumbing issue he had.  He was a good neighbor. 
 
I also don't use stud finders any more.  They don't always work.  I use a 18 gauge brad nail 2 inches long.  It makes a tiny hole and is way too fragile to damage plumbing.  You can also feel the difference of hitting wood.  If the wall is framed right, you find one and then check at 16 inch intervals to be sure you know where the others are.  Takes very little time.
