Water Line Replacement – TV Highway Corridor, Aloha
The homes in the residential blocks behind Tualatin Valley Highway span a wide age range — some built as early as the 1960s, the newest from the mid-1980s. That means the water service lines feeding these homes span a range too: galvanized steel in the oldest homes that has been corroding for 50-plus years, early copper in the middle era that's entering its own aging window. When a service line in this part of Aloha finally needs replacing, we do it right — PEX from the meter to the house, with directional drilling where the property layout allows.
What's Underground in TV Highway Corridor Homes
The oldest homes along the TV Highway residential streets — those built in the early to mid 1960s — frequently have original galvanized steel service lines. Galvanized corrodes from the inside outward, building up rust and mineral scale on the interior pipe wall and gradually narrowing the opening. The process is slow enough that pressure drops go unnoticed for years. By the time morning water runs orange or pressure has dropped noticeably at multiple fixtures, the pipe has typically been in active corrosion decline for a long time.
Homes from the 1970s and 80s in this corridor often have copper, which holds up better — but even copper service lines in the ground for 40-plus years can develop pitting corrosion from the slightly acidic water in the Portland area, leading to pinhole leaks that show up as unexplained wet spots in the yard or a water bill that crept up without obvious cause.
Aging Galvanized vs. New PEX
Aging Galvanized Steel Line
- Corrodes from inside → rust in water
- Interior narrows over decades → low pressure
- 50–60 years old in oldest corridor homes
- Rigid → root pressure at fittings causes failures
- No repair option once corrosion is advanced
New PEX Service Line
- Corrosion-resistant — no rust, no narrowing
- Full pressure maintained for 50+ years
- Flexible — tolerates root pressure and soil shift
- 50+ year rated lifespan
- Clean water from day one
Signs Your Water Line Needs Replacing
- Orange or rust-tinted water, especially the first draw of the morning
- Water pressure lower than it used to be at multiple fixtures
- Unexplained increase in the monthly water bill
- Wet, soft, or unusually green patch of yard along the line route
- Sound of water running when all fixtures are off
- Home built before 1980 with no record of water line replacement
Directional Drilling on Flat Aloha Lots
The flat lot lines in the TV Highway corridor neighborhoods are straightforward for directional drilling — no hillside grade complications, typical residential lot widths, and clear line routes from the meter at the street to the house. A Ditch Witch boring machine pulls the new PEX line underground without opening a trench. The driveway stays intact, mature trees along the route aren't disrupted, and the yard is largely undisturbed. Where soil conditions or routing require excavation instead, we explain why before we start and walk you through what the work involves.
- Directional drilling where lot and soil allow — minimal surface disruption
- Traditional excavation when routing 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 water pressure has been getting worse for years. Is that the service line?
In a TV Highway corridor home built before 1980, gradually worsening pressure almost always points to a galvanized service line that's been corroding from the inside for decades. The narrowing is so slow that homeowners adjust to it without realizing what's happening. A plumber can confirm the pipe material and assess how far the corrosion has progressed.
Can the old galvanized line be repaired instead of replaced?
Galvanized steel at this age can't be repaired in any meaningful way — the corrosion is throughout the pipe, not at a single point. The only fix is replacement. Copper can sometimes be repaired at a pinhole, but if the pipe is 40-plus years old, more pinholes typically follow. We'll give you a straight answer on what makes sense for your specific line.
How long does the job take?
Most water line replacements in the TV Highway corridor are done in one day. Water is restored before we leave.
