Professional Plumbing Inc. provides precise sewer line locating services throughout Huntington Beach, from older neighborhoods near downtown to newer developments around Huntington Harbour. We’ve been mapping underground utilities since 1985, and we understand the unique challenges of locating pipes in sandy soil near the beach and clay-heavy areas inland from Pacific Coast Highway.

The Mystery Under Magnolia Street
About five years ago, we got a really interesting call from a homeowner near Magnolia Elementary who was trying to build a deck in his backyard. He’d gotten three different opinions from contractors about where his sewer line was located, and all three were completely different. One guy said it ran along the back fence, another thought it went straight out from the house, and the third wasn’t sure but wanted to start digging anyway.
The homeowner was smart enough to call us first. We brought out our electronic locating equipment and discovered his sewer line actually curved in an S-shape through his yard to avoid an old tree that had been removed years ago. The original builders had to work around that tree, so the pipe took a winding path that nobody expected. If any of those contractors had started digging where they thought the line was, they would have missed it completely and probably hit his sprinkler system instead. We marked the exact route with spray paint, and he built his deck safely without any surprises.

Advanced Technology Makes All the Difference
Sewer line locating used to be mostly guesswork, but today’s high-tech equipment gives us incredibly accurate results. We use electromagnetic pipe locators that can trace metallic pipes from the surface, and ground-penetrating radar for non-metallic lines like PVC and clay.
Our latest electronic equipment sends signals through your sewer lines that we can track from above ground. This method works even when pipes are buried several feet deep or run under concrete driveways and patios. The signal strength tells us not just where the pipe is, but how deep it’s buried.
For complex properties or when we need extreme precision, we bring in our ground-penetrating radar system. This new technology creates detailed images of everything underground, showing us pipes, old foundations, utility lines, and even large tree roots that might interfere with your project.
We also use video inspection cameras in combination with locating equipment. The camera shows us what’s inside the pipe while our locating gear tracks its exact path from above. This gives us a complete picture of your sewer system’s condition and routing.
Why Guessing About Pipe Locations Costs Money
Some contractors will tell you they can “eyeball” where your sewer lines run based on your house layout, but this approach leads to expensive mistakes. We’ve seen contractors hit sewer lines, water mains, gas lines, and electrical cables because they didn’t locate properly first.
When someone hits your sewer line during construction, you’re looking at emergency repairs, possible property damage, and delays to your project. Plus, many cities require professional line locating before issuing permits for major construction work.
Even if you think you know where your pipes are, settling and ground movement over the years can shift their exact position. Tree roots can also push pipes out of their original alignment, especially in older Huntington Beach neighborhoods with mature landscaping.

Common Locating Mistakes That Cause Problems
The biggest mistake is assuming your sewer lines run straight from your house to the street. Many older homes have sewer lines that curve around obstacles, follow property lines, or connect to neighbors’ lines in shared easements. Without proper locating, you might dig in the wrong spot entirely.
Another problem we see is people trying to use basic metal detectors to find sewer pipes. Metal detectors can find cast iron or steel pipes, but they won’t locate PVC, clay, or concrete pipes. Plus, they can’t tell you how deep the pipes are buried or which direction they’re heading.

What Local People Say About Us
Sewer Line Locating Questions
How accurate is professional sewer line locating?
Our electronic equipment is accurate to within 2-3 inches horizontally and can determine depth within 6 inches. This precision is more than adequate for safe excavation and construction planning around your sewer lines.
Can you locate sewer lines under concrete?
Yes, our equipment works through concrete, asphalt, and other hard surfaces. The signals penetrate these materials easily, so we can map lines under driveways, patios, and sidewalks without any problem.
Do you mark the lines permanently?
We use spray paint for temporary marking that lasts several weeks. For permanent marking, we can install small flags or stakes, though most homeowners prefer temporary marking since it eventually fades away naturally.
What if my sewer lines are really deep?
Our equipment can locate lines up to 15 feet deep in most soil conditions. Huntington Beach’s sandy soil actually makes deep locating easier because the signals penetrate well without much interference.
How long does sewer line locating take?
Most residential properties take 30 minutes to 1 hour for complete line locating. Larger properties or complex layouts might take longer, but we’ll give you an accurate time estimate when we arrive.
Will locating damage my landscaping?
Not at all. Our equipment works entirely from the surface without any digging or invasive procedures. We’re careful around planted areas and always clean up any spray paint overspray.
