I have a very slow leak, maybe a drop every 15 seconds or so, in a PVC pipe that feeds an irrigation system. The leak is in a joint in a very short length of pipe, outside, where the water exits the house. The piping has a number of bends with very short straight connectors. No real good point to cut it apart to fix the leak. To fix it I’d pretty much have to rebuild the whole thing. Is there any product I can use to repair this leak from the outside?

Check with your local plumbing supply houses. They may have it in stock which would save you both waiting time and shipping charges.
lowes sells a productfor pvc,shhoot the spot with a needle,probably work on drain lines,don't know about pressure.larry
hand me the chainsaw, i need to trim the casing just a hair.
Get a coupling, and cut it lengthways so that there's about 55% of it left. Apply adhesive/cement to both the piece and the line, then snap the saved piece over the place with the leak.
All the best...
To those who know - this may be obvious. To those who don't - I hope I've helped.
You also have to file out that little ridge that runs around the inner center diameter of the coupling.
A good heart embiggens even the smallest person.
Great ideas. The area to be patched is only about an inch and a 1/2 long so the piece of coupling will have to be pretty small.
Thanks,

Cut a coupling in half, lengthwise and across. Turn off the main supply, open up a faucet. If you can suck on the pipe to creat negative pressure, suck glue into the crack. Then glue the piece of coupling over the leak.
this worked for me a couple of times on new constuction.
hook up a vacumn to the system wearever you can.apply the proper cement/solvent for what you have .put on a dab as you shut the vacumn off. this only works if the leak is in an accesible area.i'm sure plumbers wouln't like it but in your own house why not try it?
