Broken U/G conduit.... am I missing something ?

No, just ran a rag through as a rabbit.

But you’re right, i need to pull a piston through. That should give me a clear answer.

Thanks !
If you do it in both directions and the distance from each side that it hangs up adds up to about the total length of the pull string, then you know the problem is localized to one place. If not then you probably have even bigger problems.
 
[Re: inspection camera]
That was my recommendation originally; they don’t want to pay. I’m not paying for it.

Given that you already have a string pulled, pulling a cheap-o 'bullet' action cam might be a cheap answer. You don't need a high fidelity video with expert analysis of the sewer breaks; you simply need to find the damn hole!

Does anyone make a camera like a cable ferret except with internal storage that can go on the end of a duct rodder?
 
For $35, I might try to rig this up to something to pull through the conduit. Maybe a little kids toy car? This thing has nite vision too. It might give you enough information to find what you need to find.

 
Here’s a screenshot of plans that shows my conduit run.

This line was taken from as-builts.

You will notice there is an outline of a box about 150-ish feet in from the right side. I’ve already dug that up and nothing is there.

I was told that was the location of an old existing padmount transformer, and they didn’t turn off the CAD layer for that object when finalizing the drawings.

You said you dug there, but could have been a vault under the old transformer, they don’t do it here in the south that I have seen, but pretty common up north. Maybe drawn on the prints in the wrong location. Still the chances getting a rat across into another pipe would be slim.
 
Here's an idea that just came to me:

Cap both far ends, blow the string again, and see if it pops up next to where you're blowing.

If it does, that means there's a volume large enough for the string to have made a U-turn.

Thing is if you wanted it to make the U turn it never will.

Just like when you want a fish tape to push straight thru a 4 x 4 box it always pops out the box, but if you want it to pop out it always pushes through.
 
Couple of companies make self contained video cameras with recorders for the water well market. I don’t have one of these but I do have corded systems with up to 2000 ft of armoured coax cable, where you’re watching a screen with depths encoded into the display

How much do those cameras cost?
 
Since you have a string in it, could pull back a #12 stranded, and use an underground tracer to see if it makes any weird turns or offsets. That might give an indication of where a possible location of the problem may be.
