Water Line Replacement – Bethany, Beaverton OR
True Flow Plumbing replaces water service lines throughout Bethany. Bethany's hillside development took place primarily in the 1990s and early 2000s — homes in the earlier part of that range were built with copper water service lines, the standard material before PEX became widely adopted. Portland metro's soft water chemistry is hard on copper over time, causing pinhole pitting that worsens gradually until leaks appear. Bethany's hillside lots also add a variable that flat neighborhoods don't have: soil movement on a slope puts additional stress on rigid copper fittings. When a Bethany copper service line starts showing problems, PEX is the right replacement — flexible, corrosion-resistant, and rated for the next 50-plus years.
Copper vs. PEX in Bethany's Build Era
Bethany development started in the early 1990s and ran into the 2000s. Homes from the early-to-mid 1990s were almost certainly built with copper water service lines — that was the standard. By the late 1990s and into the 2000s, PEX was becoming more common and many builders had switched. If your home is early Bethany construction and you haven't had the service line replaced, there's a reasonable chance it's copper that's now 25-plus years old in a soft-water environment.

Directional Drilling on Bethany Hillside Lots
Bethany's hillside terrain is more complex than the flat tract lots in Cedar Hills. Slopes, retained trees, and longer meter-to-house distances on some lots require more careful routing assessment. That said, directional drilling works on most Bethany properties — the boring machine can navigate moderate grade changes and route around obstacles without opening a continuous trench on sloped ground. We assess each property individually, determine the best path for the new PEX line, and explain the installation approach before any work begins. On lots where slope or obstructions make directional drilling impractical, we use targeted excavation and explain why.

- Directional drilling on most Bethany lots — hillside and landscaping protected
- New PEX service line — corrosion-resistant, 50+ year rated
- Washington County permit handled
- Water restored before we leave
- Most replacements completed in one day
Frequently Asked Questions
My Bethany home already has PEX. Does that mean I don't have water line concerns?
If it was built with PEX from the start, the supply line from the street is likely PEX as well — no soft water pitting concern. The main things to watch on a Bethany PEX home are the fittings and connections rather than the pipe itself, and those are generally low-maintenance. If you're seeing pressure issues or unexplained wet areas, we can assess whether the issue is the service line or something on the house side.
How long does a Bethany water line replacement take?
Most Bethany service line replacements are completed in one day. Hillside lots with more complex routing can occasionally run into a second day, but that's the exception. We'll give you an honest assessment of the timeline when we see the property.
Do you serve all of Bethany?
Yes — all Bethany hillside subdivisions, the Springville Road corridor, NW 185th area, and every residential street throughout the Bethany community.
