Identifying Your Sewer Problem With a Video Pipe Inspection

Our Washington plumbing experts will perform a video pipe inspection before carrying out any work on your sewer pipe system. This initial inspection will give us a closer look into your sewer line so we can provide you with the most accurate solution.

The video pipe inspection process will involve running a flexible cable through the sewer lateral. Attached is a small, high-definition camera to capture the situation inside the pipeline. Our sewer experts will be able to identify the source of the problem and determine whether your sewer issue is caused by a blockage, a leak, or decaying pipe material.

Once we have a better understanding of what’s happening inside your sewer line, our Washington plumbers will explain the problem to you and go over the best solution.

Sewer Line Replacement vs. Sewer Line Repair

If the problem is isolated to a specific section of your sewer line, our Washington plumbers can typically help you resolve the issue with sewer line repair. Our sewer experts can easily replace the affected portion and have your plumbing system running efficiently again as quickly as possible.

However, you may need to consider a full sewer replacement if our plumbers find extensive damage or decay throughout the length of your sewer line. This may be the case for properties that have older pipe materials in place, such as Orangeburg, cast iron, or clay pipes that have deteriorated beyond repair.

If we find signs of pipe deterioration, we will recommend sewer line replacement as a long-term solution, so you can avoid further plumbing problems in the future. Our plumbing experts can help you replace older sewer pipes with more durable materials such as PVC or ABS pipes.

Frequently Asked Questions about Sewer Line Replacement in Mount Vernon, WA

It depends on the pipe material. Clay and cast iron sewer lines typically last 50 to 75 years, while Orangeburg pipe, which was common in homes built before the 1970s, often fails much sooner. Modern PVC and ABS pipes can last 100 years or more when properly installed. If your home is several decades old and still has its original sewer line, it’s worth having it inspected before problems start.
Many residential sewer line replacements are completed within a few days, though the timeline depends on the length and depth of the line, the replacement method, soil conditions, and any permits required. Our plumbers will give you a clear estimate of the project timeline before work begins so you can plan ahead.
Water use will be limited during the replacement, since wastewater can’t flow out of your home while the line is disconnected. That means avoiding toilets, showers, sinks, dishwashers, and washing machines during the work. We’ll let you know in advance when service will be interrupted and when it’s safe to use your plumbing again.
Yes. Standard home inspections usually don’t include the sewer line, and a damaged line can be one of the most expensive repairs a new homeowner faces. A sewer video inspection shows the condition of the pipe before you close, giving you the information you need to negotiate repairs or plan for future replacement.
The cost depends on the length of your sewer line, how deep it’s buried, the replacement method, and what’s above it, such as landscaping, driveways, or patios. After inspecting your line, a CPI plumber will provide upfront pricing before any work begins. We also offer flexible financing options with approved credit to help make sewer replacement more manageable.
