Understanding Sewer Camera Inspections

A sewer camera inspection is the single most valuable diagnostic tool available for residential plumbing. It gives you — and your plumber — a real-time, high-definition video view of the inside of your sewer and drain pipes without any digging, demolition, or guesswork.

For Duluth homeowners, where aging sewer infrastructure is common and pipe conditions vary widely from neighborhood to neighborhood, camera inspection is the foundation for informed decision-making about your plumbing system.

A sewer camera is a small, waterproof, high-definition video camera mounted on a flexible cable. The camera is inserted into the sewer line through an existing access point — usually a cleanout, roof vent, or toilet opening — and advanced through the pipe while transmitting live video to a monitor.

The camera records everything it sees: the pipe material, joint conditions, interior surface condition, blockages, root intrusion, cracks, corrosion, scale buildup, and any other defects. The footage is recorded for documentation and can be shared with you for your records.

Camera inspection is recommended in several situations that Duluth homeowners commonly face.

Modern sewer cameras detect a wide range of pipe conditions that would otherwise require excavation to discover. The most common findings in Duluth area inspections include tree root intrusion at pipe joints, clay pipe joint separation, cast iron corrosion and scaling, bellied sections where the pipe has settled creating a low spot, cracks and fractures, grease buildup, and occasionally foreign objects lodged in the line.

The camera also measures the pipe diameter and identifies the pipe material, which is important information for planning any repair work.

A typical residential sewer camera inspection takes 45-90 minutes. Our technician inserts the camera at the best available access point and advances it through the full length of the sewer lateral — from the house to the city main connection. As the camera moves through the pipe, the technician notes findings and documents the distance from the access point for each observation.

After the inspection, you receive a summary of findings with our assessment and recommendations. If repairs are needed, the camera footage provides the precise location and nature of the problem, allowing for targeted and cost-effective solutions.

At Duluth Plumbing, camera inspection is included at no separate charge with all repair assessments. We also offer standalone camera inspections for home buyers, sellers, and homeowners who want a proactive checkup on their sewer system.
