Main Drain Camera Inspection: What Homeowners Need to Know

According to a 2024 study, approximately 33% of water mains in Canada are over 50 years old, and what’s the average failure age? 53 years. So, if you’re still looking for a sign to schedule your main drain camera inspection, this might be it.

But before reaching out to experts, let’s see what this inspection is, what it includes, how much it costs, and when you really need it.

What Is a Main Drain Camera Inspection?

A main drain camera inspection is a precise, yet non-invasive diagnostic service where a flexible cable with a waterproof camera is sent through your main sewer line (usually via the clean-out).

• What’s the purpose? Whether it’s a part of a broader plumbing inspection or a separate service, the real-time footage allows the inspector to detect clogs, leaks, installation errors, etc.
• Who needs it? Sewer camera inspection mainly helps homeowners who face recurring issues with their drains and toilets, or those who are planning to sell their property.
• Why does it matter? This inspection gives you crystal clear information for targeted repairs without unnecessary digging. You can also use the record for maintenance or negotiation.

When Should You Get a Drain Camera Inspection?

There are obvious warning signs, and as soon as they begin to surface, you should book an appointment:

• Persistent drain issues: Ongoing clogs, slow drainage (across multiple fixtures), sewage backups, foul odors, or gurgling noises point to deeper problems that only a plumbing camera inspection can confirm.
• Foul odors: Smelling sewage in or around the house is another sign, especially if you’ve ruled out dry P-traps, garbage disposal residue, or floor drain buildup.
• Foundation or landscaping clues: Are there soggy patches in your yard or water damage in the basement? If so, there might be leaks or damaged sections. A camera (and sometimes, a basement inspection) will pinpoint the source of the problem.
• Preventive maintenance: Regular main drain camera inspection is an absolute must for houses with old plumbing or full-grown landscaping. This is even more important if you're planning renovations or remodeling.
• Buying or selling a house: Always schedule a sewer-scope inspection before signing on the dotted line. By providing visual data on pipe condition, it gives you negotiating power while protecting against thousands in unexpected repairs.
• Water damage: In addition to the basement, mold or water damage on the walls and floors anywhere in the house signals a problem as well.
• Mishaps: If you’ve dropped a valuable item down the drain, a plumbing camera inspection is an effective way to find and retrieve the item. Don’t use the drain until that time!

How Much Does a Main Drain Camera Inspection Cost?

A basic drain camera inspection costs between CAD 100 and 300, especially when a clean-out provides easy access. Commercial buildings, more detailed inspections, or harder-to-access setups can push the average price higher.

Let’s review the important cost influences for a better idea:

• Accessibility: If your system has an accessible clean-out, costs are generally at the lower end; without it, inspections often require toilet removal or excavation, which raises the costs.
• Pipe length and complexity: Longer drains with multiple bends and turns take more time and effort to inspect, and result in higher fees.
• Scope of service: A basic view-through may cost $100 to $300, while full reports or follow-up inspections can range from $300 to $500 or more.
• Location and urgency: Urban areas or emergency bookings typically cost more; rural or off-hour services might too. This is also true for other services, such as bathroom inspection.

Note! A Toronto condo owner shared that the camera alone was billed at $300, before labor and travel. So, examine the drain camera inspection cost quotes carefully.

What Does a Drain Camera Inspection Include?

A typical sewer camera inspection begins with inserting the camera into the main drains or clean-out to monitor and record live video feed for accurate diagnosis. This process includes:

• Detecting clogs, grease buildup, debris, or foreign objects.
• Identifying structural problems such as cracks, corrosion, misaligned joints, or sagging in the drainpipe.
• Assessing tree root intrusion or other external damages.
• Evaluating pipe slope and flow efficiency.
• Documenting the main drain camera inspection findings via video and written report.
• Follow-up recommendations for cleaning, hydro-jetting, or repairs if needed. (Click here to see what hydro-jetting is)

Benefits of Main Drain Camera Inspections

This service doesn’t just detect current issues; it provides insight to protect your property’s infrastructure and make informed maintenance or real estate decisions.

In a nutshell, the key benefits are:

• Detecting small clogs, grease buildup, or debris before they turn into full backups.
• Early spotting of structural damage, pipe misalignment, or root intrusion to avoid expensive repair or replacement.
• Having a clear record of the condition reassures both homeowners and buyers, as well as reducing uncertainty in negotiations.
• Prioritizing repairs or cleaning based on the actual pipe situation rather than speculation.
• Extending the lifespan of existing plumbing by early detection and timely intervention.

FAQ

How long does a main drain camera inspection take?

A normal sewer camera inspection usually takes about an hour.

Do I need a drain camera inspection if I don’t have issues?

If you’re not keen on proactive measures, not necessarily. If your drains are flowing well, there are no odors or backups, and your plumbing is relatively new, you may be able to skip it for a while.

Can I do a camera inspection myself?

Technically, you could rent or buy a consumer-grade drain camera, but keep in mind that DIY attempts are prone to missing problems or causing damage. Professional plumbing camera inspections are much more accurate and safer. 

What if a serious blockage is found?

You’ll need a plumber to remove it with a hydro-jet or motorized snake. They may recommend repairs if the pipe is damaged, too.
