Repair drain pipe with epoxy on the outside

[baskervi]

We have a damaged 3" PVC pipe a few inches from a cross fitting. Everything is dug up, the hole is found, and the tree root is removed, but I was wondering what the possibility of using epoxy putty on the outside of the pipe to fix the problem area. The hole is approximately 3/8" wide by 1.5" long. I've seen epoxy lining on the inside, so I figured this might work. Thanks

How about getting a banded coupler. Remove the rubber, and slice the rubber long ways. Put it around the pipe with the slit opposite to the damage. Then put the stainless steel band around the rubber, and tighten.

The coupling would be a Fernco 3005-33.

I am not a pro.

Thanks, Reach4 - I like this idea. I might feel a little more comfortable cutting out a piece of pipe to prevent having a slice in the rubber where there may be a potential leak in the future. This happened at the right time - we had the tile pulled up to do a bathroom remodel when we had to unclog the sewer pipe again, but in the future, I won't have this luxury. Thanks for your input, and I'll certainly consider this.

Also, you can use unbanded rubber couplings underground. If you put in a new section of pipe to replace a cut-out section, you use two couplings. Dish detergent is good as a lube to slide the rubber over pipe.

Repair coupling, cut in half to allow one side to be longer so that you can snap that side into place, prime and glue it.
