Sewer camera inspection: what the video shows and when to order one

A plumber pushes a waterproof camera on a stiff cable through a cleanout and records the pipe from the house toward the city main. The video shows roots, cracks, shifted joints, sags and the pipe material, and a locator in the camera head marks where each defect sits in the yard. Fixr lists $300 to $600 for a video inspection added to cleaning or repair.

Sewer lateral from house to city main The building drain leaves the foundation and passes a two-way cleanout near the house. The sewer lateral slopes down through the yard, past the property line, to the city main under the street. Roots enter at an old joint. Lining cures a new pipe inside the old one; bursting pulls a new pipe through and splits the old one.

The camera enters at the cleanout and travels down the lateral toward the main. The footage counter gives the distance to each defect.

When to order an inspection

  • Before buying an older house, especially one with large trees near the sewer route. General home inspections often don't include the sewer line.
  • After a second backup in a year, to find the cause instead of clearing it again.
  • Before accepting a repair quote, so you can see the problem the quote is for.
  • After a repair or jetting, to document the finished pipe.

What to ask for

An inspection is only useful if you keep what it found. Ask for the video file, not just a verbal summary; the footage counter showing distance from the entry point; marks or flags in the yard where defects sit, with depth readings; the pipe material and any change in material along the run; and a written list of defects. Some inspectors grade defects with a standard coding system used across the sewer industry, which makes two companies' reports easier to compare.

What the inspection costs

Fixr's January 2025 sewer cleaning guide gives $300 to $600 for the cost of cleaning or repair work when a video inspection is required, and it frames the camera as part of that job rather than as a standalone service. Standalone inspections for home buyers are priced separately by each company, so ask for the price with and without cleaning. If the line has to be cleared first, Fixr's figures for that are $150 to $375 for snaking and $250 to $800 for clearing a clogged sewer line.

Reading the report

A few terms come up in almost every report. Offset means two sections no longer line up. Belly means a low spot that holds water. Infiltration means groundwater entering the pipe. Deformation means the pipe has lost its round shape. Tap is the connection to the city main. When a report recommends work, it should say where, over how many feet and by which method. The options are compared on our sewer line repair page, and routine clearing on the drain cleaning page.

Camera inspection and a home purchase

For buyers, the timing matters more than the price. The inspection has to happen during the contingency period, the seller has to allow access to a cleanout, and a finding needs time for a repair quote. If the house has no accessible cleanout, the inspector may need to pull a toilet, which the seller should agree to in advance.

Camera inspection details

Can the camera go through a toilet?

It can, after the toilet is removed and the camera enters through the floor flange, but bends in the fixture drain make it harder. A cleanout gives a straighter view and is the usual entry point.

Does the line need to be cleaned first?

Often, yes. The camera can’t see through standing sewage or a blockage, so a clogged line is cleared before it is filmed. That is why video inspection is frequently priced as an addition to cleaning.

How long does an inspection take?

Filming a typical house lateral takes well under an hour once the plumber is set up. Locating and marking defects in the yard adds a little more.

Will the city inspect its part of the line?

Some cities film public mains on their own schedule, but they rarely inspect a private lateral on request. If the camera shows a problem at or past the property line, send the footage to the city’s sewer department.
