Sewer line replaced, now freshwater leak??

[Rivy S.]

I have a rental property here in DFW that had sewer backups several times in a row about 6 months ago.  I had a plumber camera the line and it was completely corroded (this was 2 months after I bought it).  I coughed up 14k to replace the entire sewer line. Since the day that the replacement was done, the tenant says there's one spot in the tile that is constantly wet, as well as an area on the outside of the  house.  So it sounds to me like the plumbers who replaced the sewer line damaged the fresh water line.  Is that even possible? If so, can I make them fix it? Or am I going to have to tunnel under the house again, and spend another 14k fixing this??

@Rivy S. I don't think you are going to get them to come out and fix it. I think it would be near impossible to pin it on the prior plumbers. Sorry this is happening to you.

Just turn off all the water fixtures in the house and look at the water meter to see if it is spinning.  If it is spinning then yes you have a fresh water leak.  If not then the wastewater line may be leaking so the plumbers would need to camera the line again.  The main fresh water line probably comes to the house straight from the water meter.  Look and see if any excavating was done in that area when they replaced the sewer line.
