Repairing crushed black corrugated drainage pipe
I suspect I have a section of my 4 inch drainage pipe that is crushed. I will be digging it up soon and replacing just a section of the corrugated pipe. What options do I have to "splice" in a new section of corrugated? Do I need adapter pieces or certain fittings, etc?

It wasn’t draining at the termination point. The reason I thought it was crushed was because I put a drain bladder in there to push through any blockage. About 5 ft from the opening water started to bubble up out of the ground.
After I dug it up, turns out there’s about a 3 foot chunk of the pipe MISSING! How does that even happen. I’m sort of baffled.

Glad you found the problem! Contractors seem to often totally disregard drainage piping, or install it early in the construction process and let it get destroyed as construction equipment drives over it all for months.
I personally HATE that corrugated black pipe. I would much rather use the exterior grade PVC piping for gutters and ground drainage. But if it's only a 3' section that needs to be replaced, I'm sure that's the easier answer at this point. But I would confirm the rest of the piping is in good shape!

I put my drain bladder in the part I just dug up and was able to confirm a good flow to the termination point. Now I just have to splice a new piece in there. Yes, I might do it differently if I had to dig up the whole thing, but it's about 60 ft down my driveway and not worth changing it, at least at this point in time since this part seems to be the only problem.

Any thoughts on how this happened? I dug down pretty far and wasn't able to find any evidence of this missing piece of pipe? The part on the right I already cut to make it even for the fitting, but both ends were torn, although it did not appear that they went together.
Can't imagine how this ever worked properly (I've been in this house two years).

If the ends are torn then at some point some heavy equipment must have caught it.
Since it was buried it eventually gave way.
Who knows what happened but at least you have found the issue and it's a relatively easy repair!

Did you find the missing pieces . . . . it looks so clean, and like a uniform width (the width of a backhoe bucket) ?
And what's that horizontal white plate item in the soil; it appears to be something that was intended to distribute the weight of anything above the pipe ?
Was there such a white plate above the portion that you dug up ?

I know the pic isn't that great, but it's definitely 6in corrugated.

You need to decide whether it is 4 in. or 6 in. before you buy the repair materials.
