Hi,

Our house has a finished basement and the grey water line runs beneath the foundation concrete. We had a back-up from our septic tank recently and we found that it also poored up through some spot under the foundation. We're assuming there is a leak in the waste line running out and the water pushed up through some place in the foundation (the edge where it meets the wall).

Is there a way to determine if/where the crack is in the pipe under the foundation?

If it is cracked, can this be addressed by just filling any opening on top of the concrete floor where the water (and sometimes smell) is coming up through?

Thanks in advance for your help.
