Sewer Scope Inspections

Sewer Scope Inspections in the Yakima Valley

Most buyers spend a lot of time thinking about the roof, the foundation, and the HVAC system, but almost no time thinking about what’s underneath the yard. Sewer lines are one of the most expensive components of a home to repair or replace, and they’re completely invisible during a standard walkthrough. A sewer scope inspection changes that. At Arrowhead Inspections, we send a high-definition camera through the main sewer line so you can see exactly what’s going on underground before you commit to a purchase.

We serve buyers throughout the Yakima Valley and Tri-Cities region, including Yakima, Kennewick, Richland, Pasco, Sunnyside, Zillah, Toppenish, and surrounding communities.

What Is a Sewer Scope Inspection?

A sewer scope inspection uses a flexible fiber-optic camera that travels through the home’s main drain line from the cleanout or a ground-floor access point. The camera transmits live video as it moves through the pipe, giving the inspector a real-time look at the interior condition of the line all the way to the city sewer connection or septic tank inlet. The entire process typically takes 45 to 60 minutes, and the footage is recorded and included in your inspection report.

What We Look for During a Sewer Scope

Sewer lines can fail in several ways, and each one shows up differently on camera. During a sewer scope inspection, we look for:

• Root intrusion. Tree roots are the most common cause of sewer line problems in older neighborhoods. Roots follow moisture and can work their way into pipe joints, cracking them open over time and eventually causing backups or complete blockages. In established neighborhoods throughout Yakima, Sunnyside, and Toppenish, where mature trees are common, root intrusion is something we find regularly.
• Pipe corrosion and deterioration. Older homes built before the 1980s frequently have cast iron or Orangeburg pipe, both of which degrade over time. Cast iron corrodes from the inside, and Orangeburg, a tar-based material used mid-century, softens, deforms, and eventually collapses. Once we see either material in poor condition, it’s a repair negotiation you want to have before closing, not after.
• Offset joints and bellies. Ground movement, settling, and decades of soil shifting can push pipe sections out of alignment. An offset joint creates a ledge where waste can catch and accumulate. A belly is a downward sag in the pipe that holds standing water and debris, and will eventually cause problems. Both are common findings in the Yakima Valley and Tri-Cities, where varying soil conditions and seismic activity contribute to ground movement over time.
• Grease and debris buildup. Heavy buildup inside a pipe often signals years of poor drainage habits that can accelerate deterioration and increase backup risk.
• Cracks and breaks. Physical damage from settling, freezing ground, or past repairs can leave visible cracks or open breaks in the line that allow soil infiltration and affect flow.

Why Sewer Scopes Are Worth It in This Region

The Yakima Valley and Tri-Cities area have a wide mix of housing ages. Kennewick and Richland have plenty of mid-century homes. Yakima has older downtown neighborhoods with aging infrastructure. Sunnyside and Toppenish have a significant stock of older ranch-style and farmhouse properties. In any of these markets, the sewer line is one of the first things we recommend adding to a standard home inspection, particularly if the home is more than 25 years old or has mature trees anywhere near the property line.

A full sewer replacement can run anywhere from $8,000 to $20,000 or more depending on depth and access. The cost of a sewer scope inspection is a fraction of that, and the information can be used to negotiate seller credits or avoid a property with a serious hidden problem altogether.

Combining a Sewer Scope With Your Home Inspection

Scheduling a sewer scope at the same time as your home inspection is the most efficient approach. We can complete both in a single visit, minimizing the time you need to coordinate access with the seller’s agent. Your final report will include both the standard inspection findings and the sewer camera footage with documented observations.
