For decades, diagnosing sewer line problems required frustrating guesswork. Plumbers made assumptions based on symptoms. The only way to truly know what was happening was to dig up the pipe. This led to unnecessary, expensive, and destructive excavations. Today, a sewer camera inspection takes the guesswork out of sewer repair.
A sewer camera inspection is the most effective way to diagnose underground plumbing problems. It provides a real-time, high-resolution look inside your pipes. A trained technician can pinpoint the exact cause, location, and severity of any issue. At Repipe Solutions Inc., a camera inspection is the first step in almost every sewer service we perform.
This guide explains what a sewer scope inspection is, how it works, and what it reveals about your plumbing.
What is a Sewer Camera Inspection?
A sewer video inspection uses a specialized, waterproof camera to travel through your sewer line. The camera attaches to a flexible fiber-optic cable. A technician inserts the cable through an accessible cleanout port. It travels the entire length of the pipe to the municipal sewer main.
Powerful LED lights illuminate the pipe’s interior. The camera transmits a live video feed to a high-resolution monitor. You and the technician see exactly what’s inside your pipes in clear detail. The footage can be recorded for future reference.
The equipment also includes a radio transmitter. This helps locate the exact position and depth of the camera from the surface.
How the Plumbing Camera Inspection Process Works
A professional drain camera inspection is straightforward and non-invasive. Here’s what to expect:
1. Locate Access: The technician finds a suitable access point to your main sewer line. This is typically a cleanout in your basement, crawlspace, or yard.
2. Insert the Camera: The camera and cable enter the cleanout carefully. The technician feeds them into the pipe.
3. The Inspection: The technician navigates the camera through the pipe while watching the monitor. They examine the pipe walls, joints, and water flow closely.
4. Identify Problems: As the camera moves, the technician identifies and records any issues.
5. Locate from the Surface: If a problem appears, the technician pinpoints its exact location and depth. This is crucial for planning a targeted repair.
6. Review and Recommend: After the inspection, the technician reviews the footage with you. They explain findings and recommend the best course of action.
What Problems Can a Sewer Line Camera Inspection Detect?
A sewer camera inspection diagnoses a wide range of sewer line problems:
Tree Roots in Sewer Line: The camera clearly shows fine, hair-like roots or large, dense root balls inside the pipe.
Blockages: It identifies the exact nature of a clog. This includes grease buildup, foreign objects, or “flushable” wipes.
Cracked or Broken Pipes: High-resolution video reveals cracks, fractures, and holes in the pipe wall. It catches even small ones just beginning to form.
Corrosion and Deterioration: For older cast iron pipes, the camera shows internal corrosion, rust, and scaling.
Bellied or Sagging Pipes: The camera reveals pipe sections that have sunk into the ground. These “bellies” collect water and waste.
Separated or Offset Joints: It shows where pipe sections have become misaligned or separated. Gaps allow sewage to leak out and soil to enter.
Pipe Material: The inspection confirms your pipe material (clay, cast iron, PVC). This helps determine age and condition.
What a Camera Inspection Can’t Find
While incredibly powerful, a sewer scope inspection has some limitations. It cannot detect:
Leaks Directly: A camera sees cracks or holes that cause leaks. However, it cannot see the leak itself or measure water escaping into soil.
Pinhole Leaks: Very small leaks may not appear on camera. A hydrostatic pressure test may be needed to confirm them.
Problems Outside the Pipe: The camera only sees the pipe interior. It cannot detect external soil erosion or voids from long-term leaks.
When Do You Need a Sewer Camera Inspection?
A drain camera inspection provides value in several situations:
Recurring Clogs: Frequent backups deserve a camera inspection to find the underlying cause.
Before Buying a Home: A sewer inspection should be standard in any home purchase. It uncovers hidden, expensive problems before you buy.
After Professional Cleaning: Verify that drain cleaning or hydro jetting worked. Confirm the line is truly clear.
To Plan a Repair: Camera inspection is essential for planning any sewer line repair or replacement. It’s especially important for trenchless methods.
