Water Line Replacement – Palisades, Lake Oswego OR
True Flow Plumbing replaces water service lines throughout the Palisades neighborhood in Lake Oswego. Palisades homes from the 1980s and early 1990s were built with copper water service lines that are now 30 to 40 years old. Portland's soft water chemistry has been at work on those copper lines throughout their service life — and on hillside Palisades lots, soil movement adds mechanical stress on joints and fittings that flat-lot copper doesn't experience. PEX handles both problems: immune to soft water pitting and flexible enough to absorb the soil movement that stresses rigid copper joints.
Signs Your Palisades Water Line Needs Attention
- Small wet spots on walls or ceilings with no clear source
- Water bill increasing without any change in usage patterns
- Blue-green staining at faucet aerators, fixture drains, or around plumbing connections
- Soft or wet area in the yard along the service line route
- Pressure noticeably lower at multiple fixtures than it used to be
- 1980s Palisades home with original copper still in place
Hillside Considerations for Palisades
Palisades hillside lots present two considerations for water line replacement that flat lots don't. First, hillside soil movement puts mechanical stress on copper fittings over time — rigid pipe at grade changes can crack or loosen at joints from the same freeze-thaw and soil shifting that slopes experience. Second, directional drilling — the no-trench replacement method — requires an individual assessment on hillside lots. Grade changes, tight angles between meter and foundation, and subsurface rock vary by property. We assess each Palisades lot before committing to a method and explain the reasoning before work begins.

Frequently Asked Questions
My Palisades copper water line is 35 years old with no known issues. Do I need to replace it?
Not necessarily — if there are no symptoms, there's no urgency. But 35-year-old copper in Portland soft water is in the window where monitoring makes sense. Blue-green staining at fixtures, unexplained wet spots, or rising water bills are the signals to act. If any of those appear, proactive replacement before a pinhole failure is the right move. We're happy to assess the line and give you an honest read on condition rather than defaulting to replacement.
