Water Line Replacement – Bull Mountain, Tigard OR
True Flow Plumbing replaces water service lines throughout Bull Mountain in Tigard. Bull Mountain's 1980s and early 1990s homes were built with copper water service lines — now 30 to 40 years old and in the range where Portland's soft water chemistry causes interior pitting. On hillside lots, soil movement adds mechanical stress at fittings and bends that flat-lot copper doesn't experience. PEX handles both: immune to soft water corrosion and flexible enough that hillside soil movement doesn't stress the joints the way rigid copper does.

Hillside Lots and Installation Method
Bull Mountain's varied hillside terrain means the installation method depends on the specific lot. Directional drilling works well on many Bull Mountain properties — it pulls new PEX underground without opening a trench, leaving driveways and landscaping intact. On lots with significant grade changes, tight angles, or subsurface conditions that make boring impractical, we use targeted excavation. We assess every Bull Mountain lot individually and explain our method choice before any work starts.
