See the Problem. Solve the Problem. No Guesswork Required.
Professional Sewer Inspection and Locating in San Marcos
When your home experiences a recurring backup, a slow drain, or a mysterious soggy patch in the yard, the source of the trouble is usually hidden deep underground. In the past, plumbers had to rely on “exploratory digging”—effectively trenching your yard or breaking your floors just to find the issue. Those days are over.
At Pure Plumbing Company, we believe in a “data-first” approach to your home’s infrastructure. For over 10 years, we have provided San Marcos and North San Diego County with high-definition sewer inspections and precision locating services. By utilizing the best top-of-the-line equipment in the industry, we can see exactly what is happening inside your pipes in real-time, allowing us to provide surgical, cost-effective solutions without unnecessary destruction to your property.

Our Sewer Inspection & Locating Services
What We Can Identify:
Collapsed or Cracked Lines: Structural failures that require immediate repair to prevent sinkholes or foundation damage.
Root Intrusion: Hair-like roots that enter through tiny cracks and grow into massive blockages.
Pipe “Bellies”: Low spots caused by soil settling where debris and water pool, leading to chronic clogs.
Offset or Separated Joints: Sections of pipe that have shifted due to seismic activity or ground movement.
Corrosion and Scaling: Extensive mineral buildup or “channeling” in older cast iron pipes.

High-Definition Video Sewer Lateral Inspections
Our primary diagnostic tool is our high-tech sewer camera, a specialized piece of equipment designed to navigate the hidden complexities of your plumbing system. To begin the process, we insert a flexible, fiber-optic cable into your sewer cleanout or roof vent, allowing us to access the line without any invasive digging. As the waterproof camera travels through the pipes, it transmits a crystal-clear, live video feed to a high-resolution monitor, enabling our technicians to pinpoint the exact location of blockages, cracks, or root intrusions in real time.

Precision Underground Line Locating
If a problem is found, the next step is “Locating.” Our camera heads are equipped with a digital “sonde” (a signal transmitter). While the camera is at the point of the break, we use a handheld receiver above ground to pinpoint the exact GPS coordinates and the precise depth of the pipe. This allows us to mark the ground with an “X,” ensuring that if a repair is needed, it is targeted and minimally invasive.

Real Estate “Peace of Mind” Inspections
Are you buying a home in San Marcos or Oceanside? A standard home inspection rarely covers the underground sewer line. Many new homeowners are hit with a $10,000+ repair bill just weeks after moving in because of a hidden root-crushed pipe. Pure Plumbing Company provides comprehensive “pre-purchase” sewer scopes to ensure your dream home doesn’t have a hidden nightmare beneath the surface.

Signs Your Sewer Line Needs an Inspection
Not sure if you need help?
If you are experiencing any of the following, a video inspection is the only way to find the true cause:
- Multiple Fixture Backups: If your kitchen sink, shower, and toilet all gurgle or back up at the same time, the issue is in the main sewer line.
- Persistent Sewage Odors: If you smell “rotten eggs” in your yard or basement, there is likely a crack or separation in the line allowing sewer gases to escape.
- Recurring Clogs: If you have to call a plumber to snake your drain every 3–6 months, you have a structural problem that a snake cannot fix.
- Greener Patches in the Lawn: Sewage acts as a potent fertilizer. An unusually lush, green strip in your grass often marks a leaking sewer pipe

The Impact of North County’s Shifting Soil
In areas like San Marcos and Escondido, the soil can be highly expansive. As it gets wet and dry, the earth moves, putting immense physical pressure on rigid clay or cast iron pipes. Over 10 years, we have seen how these shifts cause pipes to “offset,” creating a ledge that catches debris. Our top-of-the-line locating equipment allows us to see these shifts early, potentially saving you from a total line collapse.

Sewer Inspection Faq’s
We offer flat-rate pricing for our standard inspections. Unlike “hourly” plumbers, our goal is to give you an honest diagnostic. If we find a problem, we provide a clear, upfront quote for the repair.
Our top-of-the-line cameras are designed with flexible “spring” heads that can navigate multiple 90-degree turns. If a pipe is so badly collapsed that the camera cannot pass, that in itself is a diagnostic confirmation that a repair is required at that specific point.
Yes. We can provide you with a digital link or a flash drive containing the full high-definition video of your sewer line, along with a written report of our findings and recommendations.
