Water Line Replacement – Cedar Hills, Beaverton OR
True Flow Plumbing replaces water service lines throughout Cedar Hills, one of Beaverton's oldest neighborhoods. Homes built in Cedar Hills during the 1950s and early 1960s were served by galvanized steel water lines — the standard material of that era. Galvanized steel has a service life of 40 to 70 years depending on water chemistry and soil conditions. Cedar Hills galvanized that hasn't been replaced is now at or past the end of that range, developing interior rust deposits that restrict flow, drop pressure, and can discolor the water. When a Cedar Hills service line reaches this point, the right answer is replacement with PEX rated for the next 50-plus years.
Galvanized Steel in Cedar Hills — What 60 Years Does to a Water Line
Galvanized steel pipe is coated with zinc on the interior to prevent rust. Over decades of use, that zinc coating wears away and the steel beneath begins to corrode. The corrosion doesn't create leaks immediately — it creates buildup. Interior rust deposits accumulate layer by layer, narrowing the pipe from the inside until what was once a full-diameter line is significantly restricted. Pressure drops. Water at the hot tap picks up a rust tint. The cold water at the first fixture after the meter may run slightly discolored if the line hasn't been run in a while.
This is the condition of galvanized service lines throughout Cedar Hills that haven't been replaced. It doesn't fail suddenly — it degrades gradually until the restriction becomes significant enough to notice. At that point, replacement is the only permanent solution. Cleaning the inside of galvanized is not practical.

Directional Drilling in Cedar Hills
Cedar Hills was built as a planned tract neighborhood with consistent flat lot layouts — standard meter-to-house distances and driveways that run predictably from the street. That geometry is ideal for directional drilling, which pulls the new PEX line underground without opening a continuous trench. The driveway stays intact, landscaping along the route isn't disturbed, and the yard is largely undisturbed when we finish. Most Cedar Hills water line replacements are completed in one day with water restored before we leave.
- Directional drilling on most Cedar Hills lots — driveway and landscaping protected
- Traditional excavation when routing or soil requires it
- New PEX service line rated 50+ years
- Washington County permit handled
- Water restored before we leave
- Most jobs completed in one day
Frequently Asked Questions
My Cedar Hills home was built in 1958. Has the water line been replaced?
There's no way to know for certain without looking — but if there's no record of it and the home hasn't had significant plumbing work, it may still be on original or partially original galvanized. The clearest indicator is pressure: if it's noticeably lower than a newer home or lower than it used to be, the line is worth investigating. We can assess it and tell you what you have before recommending anything.
Can a section of galvanized be replaced rather than the whole line?
A section can be replaced, but if the rest of the original galvanized is still in place, the same degradation is present throughout. Replacing a section buys time but doesn't solve the underlying condition. We'll tell you honestly whether a section repair makes sense for your specific situation or whether full replacement is the better long-term answer.
