When Should You Get a Sewer Camera Inspection?

A sewer camera inspection is usually recommended when a drainage problem keeps returning, affects several fixtures or points to an obstruction or damaged pipe deeper in the system. It is not automatically required for every slow drain or clogged toilet.

Before recommending a camera inspection, the plumber should consider which fixtures are affected, how often the problem occurs and whether the drain needs to be cleared first. This helps determine whether a camera will provide useful information or whether another diagnostic step makes more sense.

What Is a Sewer Camera Inspection?

A sewer camera inspection uses a small waterproof camera attached to a flexible cable. The camera is inserted through a suitable drain opening or cleanout and moved through the pipe while the plumber views the inside of the line on a monitor.

Depending on the condition of the pipe and how far the camera can travel, the inspection may reveal:

• Tree roots entering the drain

• Heavy grease, scale or debris buildup

• Foreign objects lodged in the line

• Cracked, broken or collapsed sections

• Separated or misaligned pipe connections

• Changes in pipe material

• Standing water or an obvious change in alignment that requires further investigation

The inspection gives the plumber a direct view of accessible sections of the drain. This can help avoid unnecessary excavation and provide better information before a repair is recommended.

When a Sewer Camera Inspection May Be Needed

The Same Drain Keeps Backing Up

A clog that clears and does not return may have been an isolated blockage. When the same drain backs up repeatedly, however, there may be an underlying issue that routine drain cleaning has not addressed.

Possible causes include root intrusion, a damaged pipe, a recurring buildup or an object that was not fully removed. Once the line is open enough for the camera to pass, an inspection can help identify what is causing the repeated problem.

Several Fixtures Are Affected

When one sink or bathtub drains slowly, the problem may be limited to that fixture or a nearby branch drain. When several fixtures are affected at the same time, the issue may be farther along in the drainage system.

Examples include:

• A toilet bubbling when a sink or washing machine drains

• Water rising in a basement floor drain

• More than one toilet draining slowly

• A bathtub or shower backing up when another fixture is used

These symptoms do not confirm that the main drain is damaged, but they justify a closer look at the drainage system. A camera inspection may be part of that diagnosis once any immediate blockage has been addressed.

Drain Cleaning Has Not Solved the Problem

Drain cleaning removes an obstruction, but it does not repair a damaged pipe. If a line has been cleared and the problem returns, a camera can help determine whether something in the pipe is contributing to the repeated blockage.

The inspection may show roots, a broken section, a displaced connection or buildup remaining along the pipe walls. The results can then be used to decide whether further cleaning, a localized repair or pipe replacement should be considered.

Tree Roots or Pipe Damage Are Suspected

Tree roots can enter a drain through cracks and openings at pipe joints. Once inside, they may collect waste and gradually restrict the flow through the line.

Older drains may also develop corrosion, deterioration, separated joints or damaged sections. A camera cannot assess every aspect of a buried pipe, but it can show visible conditions that may explain recurring backups or poor drainage.

A Drain Repair Is Being Planned

A camera inspection can be useful before committing to an underground drain repair. It may help identify the affected section, show whether the problem appears localized and provide information about the visible condition of the surrounding pipe.

If locating equipment is used with the camera, the plumber may also be able to mark the position of a specific problem from above ground. This can reduce the amount of exploratory digging required.

You Are Buying or Renovating an Older Home

A sewer camera inspection is not necessary for every home purchase or renovation. It may be worth considering when the property has a history of sewer backups, mature trees near the drain route or an older drainage system with an unknown condition.

A regular home inspection generally does not include a detailed view inside the buried building drain. If there are reasons to be concerned about the sewer line, a separate plumbing assessment can provide more information before major renovations are completed.

When a Camera Inspection May Not Be the First Step

Some plumbing symptoms can have several possible causes. A camera inspection should not be treated as the answer to every drain-related concern.

One Fixture Is Draining Slowly

A single slow sink, tub or shower is often caused by a localized blockage in the trap or nearby branch drain. The fixture and accessible drain connections may need to be checked before inspecting the main sewer line.

There Is an Odour Coming From a Drain

Sewer-like odours can result from a dry trap, a loose toilet seal, a venting issue, buildup inside a fixture drain or another plumbing problem. The source of the smell should be investigated before assuming that a sewer camera is required.

Water Has Appeared in the Basement

Basement water does not always come from a sewer backup. It may be caused by a leaking water line, a water heater, an appliance, foundation seepage or surface drainage around the property.

Where the water appeared, what was happening at the time and whether it contained sewage are all important parts of the diagnosis.

The Drain Is Completely Blocked

A camera cannot provide a clear view through solid waste, heavy buildup or murky standing water. It may also be unable to pass through a complete obstruction.

In these situations, the line usually needs to be opened or cleaned before the camera inspection can provide a useful view.

What a Sewer Camera Cannot Confirm

A camera inspection is a valuable diagnostic tool, but it has limitations. It does not provide an X-ray of the pipe or test every part of the plumbing system.

A sewer camera generally cannot:

• Inspect pressurized water-supply pipes

• See through solid blockages or heavy buildup

• Confirm the source of every plumbing leak

• Assess sections the camera cannot reach

• Determine the full condition of soil surrounding a buried pipe

• Guarantee that a problem will not develop in the future

The video should be considered alongside the plumbing symptoms, the drainage history and any other inspection findings. In some cases, further testing or excavation may still be required.

What Happens During the Inspection?

The process begins with a discussion of the problem and an initial assessment of the affected fixtures. The plumber then identifies a suitable access point, such as a drain cleanout.

If the line is blocked, it may need to be cleared before the camera can be inserted. The camera is then moved through the accessible portion of the pipe while its condition is reviewed on a monitor.

Afterward, the plumber can explain what was visible and whether any further work is recommended. Depending on the findings, the next step may involve additional cleaning, monitoring the drain, repairing one section or discussing replacement options.

A camera inspection should help guide the decision. It should not automatically lead to the most extensive repair.

Sewer Camera Inspections in Thornhill, Vaughan and the GTA

Homes throughout Thornhill, Vaughan and surrounding GTA communities have drainage systems of different ages, materials and configurations. Depending on when a home was built or renovated, the underground drainage may include older clay or cast-iron sections, newer plastic piping or a combination of materials.

McPipe Plumbing assesses the symptoms and accessible plumbing before determining whether a sewer camera inspection is appropriate. If the line needs to be cleared first, that should be addressed so the camera has a better chance of reaching and showing the area of concern.

Do You Need a Sewer Camera Inspection?

Consider having the drainage system professionally assessed if:

• Backups keep returning after the line has been cleared

• Multiple fixtures are draining slowly or backing up

• A toilet bubbles when another fixture is used

• Water rises through a basement floor drain

• Tree roots or a damaged underground pipe are suspected

• A drain repair is being planned

• An older home has a history of sewer problems

Not every clogged drain requires a camera. The right starting point is an assessment of the symptoms, followed by the diagnostic work that fits the situation.
