Why the camera comes first
In an older building the drain line from the house to the street may include cast iron under the house, clay pipe in the yard and later plastic repairs, all hidden. Symptoms such as slow drains or backups tell you something is wrong but not where or why. A camera inspection records the inside of the line, so decisions about cleaning, repairing or replacing are based on what is there.
It is also a common step before buying an older property, before a remodel that adds bathrooms, or after repeated clogs that keep coming back in the same place.
How an inspection usually goes
- Access
- The plumber locates a cleanout. If none is accessible, they may go through a toilet opening or a roof vent, or suggest installing a cleanout.
- Clearing
- If the line is blocked, it may need to be cleared first so the camera can travel through.
- Recording
- A camera on a flexible cable is pushed through the line while the footage is recorded and distance is tracked.
- Locating
- Some cameras carry a transmitter so problem spots can be marked on the ground above.
- Review
- The plumber walks through the footage with you and explains what each finding means.
Terms you may hear on the video
- Cleanout
- A capped access fitting on the drain line used to inspect or clear it.
- Lateral
- The sewer pipe running from the building to the public sewer main.
- Belly or sag
- A low spot where the pipe has settled and water collects.
- Offset joint
- Two pipe sections that have shifted out of line, leaving a lip that catches waste.
- Root intrusion
- Tree roots growing into the pipe through joints or cracks.
- Scale
- Rough corrosion and mineral buildup on the inside of iron pipe.
- Transition
- The point where one pipe material connects to another, such as cast iron to clay.
How to prepare
- Know where any cleanouts are, or clear access around the foundation and crawlspace
- Avoid running water heavily just before the inspection
- Have a list of symptoms and when they started
- Ask in advance whether you can keep the video file
- If you rent or share a lateral, let the owner or other units know
What to ask for in the report
- A copy of the full video, along with any still images
- The distance from the access point to each finding
- The pipe material seen in each section
- Which findings need action now and which can be monitored
- Whether any part of the line was not viewed, and why
Common questions
Does a camera inspection fix anything?
No. It only shows the condition of the line. Cleaning or repair is a separate step, though some plumbers clear a blockage first so the camera can pass.
Can the camera see through roots or water?
Standing water in a sag or heavy root masses can block the view. The plumber may need to clear the line or note sections that could not be seen clearly.
Should I get a camera inspection before buying an older house?
Many buyers do, because sewer line problems in older properties are common and hidden. Ask for the video and a written summary to review before closing.
