I have a leak.

It's coming from what I believe is a drain/sewer line under the slab. This is a florida home, typical slab construction. When the tenant takes a shower, water is seeping up from a small crack in the foundation. It has a smell of sewage, so I've ruled out fresh water. Plus, it's only when the shower runs.

Could the crack in the drain line be the result of the slab settling?

Do I need to snake the line with a camera to locate the crack in the drain line? Or should I just go ahead with busting up the foundation and getting to the root of the problem.

Here are some pics.

I guess it could be coming from the shower enclosure. But how? Could the drain in the shower be improperly installed, allowing water to leak into the liner, filling the liner up with water, and then seeping through to the other side of the wall?
How would the water travel upwards more than 6 inches to flow out on the opposite wall?
 
The water could "wick" up the wall.
Normally, water leaking from a pipe in the ground, goes farther down into the ground.
I have seen a leak in a wood crawlspace get drywall wet six inches high on the floor above the plywood.

It may be tough to figure out, we can look at your pictures, but we're not there.

Maybe someone else will chime in on this with some good ideas.
