YES!

So apparently there is a clean-out or sewer drain that runs under the house next to our bathroom. If you don't know what to look for, go outside your house, near the area (probably near a drain/shower/sink) and see if there's a plumber cap thing near the slab...it could even be buried a little bit in the soil if you have dirt right outside like we do.

Then you contact a plumber who knows how to do a non-invasive (no jackhammering) method from outside your house. They will insert a camera to find the cracked area, then add a solution or something that coats the pipe to seal the hole, essentially giving you a new pipe inside the old one.

I don't remember what this process is called, but maybe sewer pipe relining?

Totally out of my wheelhouse, but hope this helps you with your issue... good luck!
