Sewer Scope Inspection – Palisades, Lake Oswego OR
True Flow Plumbing provides sewer scope inspections throughout the Palisades neighborhood in Lake Oswego. Palisades hillside homes from the 1980s and 1990s have PVC sewer laterals that are 25 to 40 years old — still structurally sound, but the hillside terrain that defines the neighborhood creates pipe belly risk over time as soil shifts on sloped lots. Combined with grease accumulation from three-plus decades of household use and root intrusion from maturing landscape trees, a scope gives buyers and owners the actual picture of what's in the ground.
What the Camera Finds in Palisades
Pipe Belly from Hillside Settlement
On hillside Palisades lots, soil movement over 30-plus years can cause lateral sections to sag below intended grade. A belly creates a low point where debris and water pool rather than flowing through. No surface symptoms appear until debris accumulates enough to block flow — the camera is the only way to find it.
Root Intrusion at PVC Joints
Landscape trees planted when Palisades homes were built in the 1980s and 90s are now mature — with root systems at the depth of lateral joints. The camera shows which joints have been penetrated and how much of the pipe interior roots are occupying.
Grease & Soap Accumulation
Three decades of household grease and soap scum inside PVC pipe. The camera shows the remaining interior diameter. On laterals with significant accumulation, slow drains throughout the house — not just one fixture — are the typical signal.
Grade & Joint Condition
The camera documents grade throughout the entire run, identifying any sections where slope is inadequate. Joint condition — tight, showing early root infiltration, or showing offset from hillside settling — is documented at every connection.
Lateral length and cleanout access determine placement in the range.
How the Inspection Works
- Access the cleanout. We locate the cleanout near the foundation or yard and access the lateral from there.
- Full camera run. The camera travels from cleanout to city connection. On hillside Palisades lots, we track grade changes throughout the run.
- Document findings. Belly location and severity, root intrusion, grease accumulation, joint condition, and grade are all timestamped on video.
- Plain-language report. We show you the footage and explain what it means before recommending anything. No pressure, no upsell.
