I need to move a full bath in my basement. However, the sewer line can take one of two routes to one of two streets both having sewer mains.

I have no telltale outside vents or cleanouts that I have been able to locate.

What's the best way, before I start destroying concrete, to locate the sewer line?

Thanks,

RJ

As a rule a plumber will look at a job and think, "How would I have roughed this job in?" We can come pretty close that way. Failing that I would try to locate where the sewer exits the house and work back from there.
How low do you figure the sewer is? Can you dig a lateral trench and locate it that way? how about a prob rod? Or you could get someone out there with a pipe locater,( if the pipes are metal) that will tell you exactly where the pipes are under the cement. Good luck, tom

Then my friend,. you must confuse real easy! I don't kinow how much more I can "dumb" it down for you but if you will tell me what part confuses you I'll give it a try. Do you know what the word "lateral trench" means? Any idea what a "prob rod" is?
I thought this was pretty much self-explainatory, " you could get someone out there with a pipe locater,( if the pipes are metal) that will tell you exactly where the pipes are under the cement."
Do you wish it explained farther? We are here to help. If you're confused let us help you. Regards, Tom

Some times a plumber can run his sewer machine through the sewer line and someone on the outside of the house can listen in different areas to see if they can find a noise that the sewer cable would make inside the sewer line. To help with this is to use a length of metal rod about three feet long and 3/8's in diameter to punch into the ground at different places around the house to help hear the noise. Good Luck.
