An articulate sewage system is undoubtedly a blessing for us. But often homeowners find it hard to locate their sewage lines.
Locating a sewer pipe is essential, especially in the case of installing utility sinks in garages or toilets. This keeps the contaminated water away from pure water.
But, this isn’t an easy task. That’s especially the case if you want to go all DIY. In this article, I will clearly explain all the ways you can find your underground sewage lines.
By the end of this article, this complex task will be very difficult for you to accomplish.
4 Methods of Locating Sewer Lines Underground
There are several methods that you can utilize to accomplish your goals. I have listed them below.
Method 1: Pipe Locator
Start off by setting the frequency. Both the transmitter and wand need to have the same frequency.
Locate a drain or a sewer nearby. If you have an outdoor sewer, locate a white or black pipe. This pipe usually has a plastic cap.
These will lead you straight to the underground sewer line.
Next, feed the line into the drain. Extend it up to 15 feet. Now use the wand vertically.
Move the tip frontwards and backward, occasionally, rotate it as well if you’re receiving weak signals.
If the beeping signal of the wand gets louder, you’re coming closer to your destination. If the beeping is the loudest, you’ve found the end of the line.
Keep in mind that you can frequently find rodents as well after locating the pipe. That’s why it’s wise to install rodent-proof pipe insulation.
Once you’ve found your desired point, there might be a possibility for the sensor to read a false positive or true negative.
This might be a sensitive issue if you’re drilling inside the pipe. So additionally, you can perform the low sensitivity test.
To re-confirm your finding, try lowering the sensitivity. I prefer lowering the sensitivity by 3/4th the original sensitivity.
Try locating the strongest signal again. If this matches with your previous finding you’ve confirmed your spot.
The next course of action is to mark the spot. Place a utility tape along the line of beeping.
Then, place a utility flag where the beeping is loudest. This will indicate that the sewer line is directly beneath it.

Method 2: Check With The Zoning Office of Your Locality
The zoning office is usually in possession of a utility map. They have an accurate idea of where utilities and services are located in your area.
The zoning office should be able to tell you which sewer line connects to your household.
But, some zoning offices, especially in rural areas, won’t be able to locate these.
If contacting the zoning office is possible, this is a great option as it also saves your budget.
Method 3: Check with the Previous Owner
When in doubt, it’s always wise to pick up your phone. It’s very likely that the previous owners of your idea have a great idea of where underground sewers are located.
It’s possible that you don’t have their contact information.
But, don’t worry I’ve got that covered as well. It’s possible to find the contact information of the previous owners by looking through your municipal records.
Method 4: Locating Manholes
Manholes are usually located at a distance of 100 feet from each other. Underground sewer lines can be found between manholes.
Try to find manhole covers that are very easy to spot. This will solve your problem as you can locate the sewer lines from there.
If all of these methods seem too intricate, the best option is to contact professionals. There are several advantages to this.
For example, they know double vanity plumbing installation techniques.
First of all, DIY methods have the risk of drilling through pure water lines. These risk factors can be avoided utilizing the technical expertise of professionals.
Secondly, utility locator contractors are also very affordable to hire. You won’t have to spend too much on expensive locating tools.
These methods should be adequate enough to accurately locate underground sewer lines. If you face any problems along the way, contact a plumber immediately.
Best of luck!
