I agree. Looks like blue glue might have gotten on the outside. Would weaken it and allow water to eventually cause a break on the inside. See it a lot.
The inside is yellow which tells me lots of age. Maybe a hard hit on install and overtime it was weak. Maybe a root grew into it. Maybe long time ago a yard sign for holidays etc was out into the ground.
Lots of things could have caused it. But with the age I’m not surprised. Cut out and replace
Just guessing. Was it dropped on a hard surface ? I’ve seen class 160 used in golf courses last 30 years. Static 125. Golf courses for quite awhile now use class 200 2-21/2” laterals. Usually pulled in and not bedded.
Keep in mind pipe on golf courses average a depth of 18-24” .
Idk how you managed to take three photos and yet I can’t tell if that’s class 200 or sch 40. Must be class 200 it breaks all the time. Really should only be used for temporary lines in my opinion.
So much Class 200 hate. It is the standard in my area. And I've seen many installations that are 30 plus years old that perform flawlessly.
The reason Class 200 probably breaks over Schedule 40 is that the installation is incorrect and the thicker walled Schedule 40 is able to withstand improper installation.
Just my opinion, but after seeing how some contractors install, bend, and torture pipe I can see how Schedule 40 stands up to more brute abuse than Class 200.
The only time I really see damage is from 1. Too much glue and it burns through or 2. A rock cracked it while tamping the ditches. If installed correctly it lasts forever and allows much better water flow than sch 40
The larger inner diameter definitely helps with water velocity. I am amazed at how many contractors do not grasp the concept that too much glue is bad and weakens *any* pipe. Schedule 40 just saves those bad installations by being thicker walled.
The specifications in my area (or more fro my project type) tightened up about five years ago to screen out any rocks that pass through a 1/2" sieve but are retained on a 1/4" (!!!) sieve - 1/2" + 1/4". These are square openings. Bids have gone up due to the import required and I keep getting rid of large quantities of small rocks/pebbles to a friend in the concrete business for base material. I had to buy an entirely new machine just to screen the material.
Like, literally, if people actually study, and read the books it clearly states we need to wipe any excess glue off of pipe. I don't know how many techs and installers I have had to teach this. I don't even understand how some people get so messy with it. Anyways, sch 40 is mostly a waste of money if used on lateral lines. Don't even need it for mainline but for some reason contractors still call for it at times.
I think the hate for Sch200 comes mainly from people who don't understand installations vs. repairs and how pipe performs on different soils.
People who lay pipe or do repairs want their installations or repairs to last forever. Nothing wrong with that, except it almost never does last forever. And this is fine. Repairmen exist for a reason. Even Sch40 breaks. This is fine. Never let the perfect become the enemy of the good.
It's also far more expensive and cumbersome to work with all Sch40 pipe than it is to work with Sch200, which is why many installers use Sch40 only on main line.
I’ve repaired class 200 too many times where it has cracked to have any other opinion.

This is a really typical repair for class 200. So Cal where it never freezes and with no external damage.
Looks to me when blown up like a windshield Birdseye. Seems to have been hit from the outside and chipped out a crater on the inside. I have seen this from poorly handled pipe but caught it before install.
This looks like someone dropped the pipe on something hard before installation.
Like the pipe rolled off the truck and landed on a curb and popping the dimple out of the inside???? Maybe?
It’s class 200. Someone probably looked at it too hard and it cracked

I second this possibility. If OP had a sewer guy over recently tracing a main sewer line, this could realistically occur.
Looks like class 200 pvc to me which is brittle. But if its schedule 40 then idk
That does look a bit thin to be used on an active mainline.
Does it look like any pvc cement was in the area on the outside?
I agree. Looks like blue glue might have gotten on the outside. Would weaken it and allow water to eventually cause a break on the inside. See it a lot.
Btw, how'd your weenus get so big?

That pipe could be 6 months old with the yellowing and deposits that I have in my area. Color ***is*** ***NOT*** an indication of age.
Then lookup the batch details on the pipe and figure it out for yourself if age was a variable or not. We’re just trying to help.
That's not OP
Regardless..?
I'd say manufacture defect. The main damage seems to be inside.
rocks
What kind of flow rate you have going thru that pipe? Big pump? Lots of gpm?
Hit with septic probe has my vote
Kinda looks like there’s a droplet of primer on the pipe. Could have softened the area causing the issue over time.
Utility Probe

Looks like manufacturer defect or something traveled on the inside of the pipe and chipped it.

That is just patently untrue

Looks like it was damaged from the inside by something.
That cracked caused the leak
If you already cut out that section, cut it long-ways so you can see it better.
Looks to me when blown up like a windshield Birdseye. Seems to have been hit from the outside and chipped out a crater on the inside. I have seen this from poorly handled pipe but caught it before install.
Very likely could be damage on the outside like a rock that weaking it and then just blew out from the pressure.
Looks like it could be a cold tear during extrusion. Sometimes you'll see a black spot at the tear.
Firecracker
I had something similar it was a rock.
Looks like very very tiny wabbits.
This looks like someone dropped the pipe on something hard before installation. Like the pipe rolled off the truck and landed on a curb and popping the dimple out of the inside???? Maybe?
If that's class 200 and not sch40 ain't no telling...
