Drain Cleaning – Palisades, Lake Oswego OR
True Flow Plumbing provides drain cleaning throughout the Palisades neighborhood in Lake Oswego. Palisades homes from the 1980s and 1990s have PVC drain lines that are 25 to 40 years old — still structurally sound, but on hillside lots the grade changes common in the neighborhood create pipe belly risk over time as soil shifts. Grease accumulation from 30-plus years of household use and root intrusion from maturing landscape trees round out the picture. Drain problems in Palisades need a camera to identify the specific cause — not every clog is the same on a hillside lot.
Hillside Lots and Pipe Belly: A Palisades-Specific Issue
Pipe belly — a section of lateral that has sagged below grade — is a risk on any hillside lot where soil shifts over time. On Palisades homes, belly can develop without any obvious surface symptoms until debris accumulates enough to cause a backup. A snake clears the debris in the belly, flow returns, debris accumulates again — and the cycle repeats. The only way to diagnose a belly is the camera. Once located, targeted repair of the affected section resolves it permanently.
Warning Signs
- Multiple drains slow at the same time — not isolated to one fixture
- Toilet gurgling when the washer or other drains are used
- Main line backup — water backing up at multiple fixtures simultaneously
- Recurring main line backup cleared and blocked again on a predictable cycle
- Sewage smell from a drain or from the cleanout access in the yard

Frequently Asked Questions
My Palisades drain backs up periodically. A plumber ran a snake and it cleared — but now it's slow again. Why?
On a hillside Palisades lot, a periodic backup that clears with a snake and returns again is often pipe belly. The belly creates a low spot where debris collects — the snake pushes it through temporarily, but it accumulates again in the same spot. The camera identifies the belly location and confirms whether that's what's happening. Targeted repair of the belly section is the fix — not more snaking.
