Water Line Replacement in West Union, Oregon
The West Union area of Washington County is one of those places where rural heritage and suburban growth sit right next to each other. That mix — older converted farmhouse lots alongside newer subdivisions — creates a wide range of water service line situations, and we work on all of them.
What Makes West Union Different
West Union Road and the surrounding unincorporated area between Hillsboro and North Plains developed in layers over several decades. Understanding which era your home belongs to matters a lot when it comes to water service line problems:
Older farmhouse-era properties (pre-1970s) — Large lot properties that were originally farm parcels often have water service line runs that are considerably longer than a typical suburban lot. More feet of pipe in the ground means more opportunities for a failure. Many of these lines are original galvanized steel — corroded from decades of use and long overdue for replacement.
Mid-period subdivision homes (1970s–1990s) — As Washington County grew, subdivisions were carved into the West Union area using the pipe materials standard at the time. Some of these homes have galvanized steel service lines; others have early plastic supply lines that have become brittle over time.
Newer developments (1990s–2010s) — More recent construction generally used better materials, but "newer" in the Pacific Northwest also means mature trees with established root systems. Root intrusion into service lines is one of the most common issues we see in this era of West Union properties.
Aging Pipe vs. New PEX
Old Galvanized Steel
- Corrodes from the inside out
- Rust particles reduce pressure
- Rust-tinted water at morning startup
- Especially bad on longer lot runs
- Average lifespan: 40–50 years
New PEX Service
- Corrosion-resistant — never rusts
- Full flow for the life of the pipe
- Handles soil movement and root pressure
- Works on long runs as well as short
- Rated 50+ year lifespan
Signs Your West Union Water Line Is Failing
- Steadily declining water pressure — not sudden, just slowly worse over time
- Rusty or discolored water on first use in the morning
- Unexpectedly high water bills
- Wet, soft, or unusually lush patches of grass in the yard
- Audible sound of running water when all fixtures are off
- Visible water pooling near the water meter or foundation
- Home is pre-1990s and the service line has never been replaced
Directional Drilling in West Union
For West Union properties — particularly those with longer service runs, mature landscaping, or finished driveways between the meter and the house — trenchless directional drilling is often the right method. We use our Ditch Witch boring machine to pull a new PEX water service pipe underground along a precisely controlled path, without digging an open trench the entire length of the run.
The result: a new 50-year water service installed with minimal disruption to the yard, driveway, or landscaping. For a property with established trees, a paved driveway, or a well-kept lawn, that difference is significant.
We do still excavate when the job calls for it — some soil conditions, routing constraints, or repair scenarios are better handled with an open trench. We'll be straight with you about which method makes sense for your property.
- Trenchless directional drilling available for qualifying properties
- New PEX service rated for 50+ years
- Washington County permit pulled by us
- Able to handle longer service line runs common on larger lots
- Most jobs completed in one day, water restored before we leave
- Full cleanup on completion
Frequently Asked Questions
What makes West Union properties different for water line replacement?
The mix of older farmhouse-era lots, mid-century subdivisions, and newer developments means the age and condition of service lines varies a lot by property. Older large-lot properties often have the longest runs and the oldest pipe. Newer subdivision homes may have root intrusion issues from mature plantings. We evaluate each property individually before recommending a method.
Is directional drilling possible in the West Union area?
Often yes — soil conditions in many parts of West Union are favorable for trenchless boring. For homes with longer service runs through established landscaping, directional drilling is frequently the preferred option. We'll assess your specific property and tell you honestly whether it's the right approach.
How long does a water line replacement take?
Most residential jobs in the West Union area are completed in a single day. Longer runs on larger lots may take a bit more time. We schedule jobs so water service is restored before we leave the property.
What type of pipe do you install?
We install PEX — flexible, corrosion-resistant, and rated for 50+ years. It handles ground movement and root pressure well, which makes it a particularly good choice for the larger-lot properties common in the West Union area.
My water pressure has been gradually getting worse for years. Could it be the service line?
Very possibly. Gradual pressure loss on a longer service run is a classic symptom of a galvanized steel line that has been slowly corroding and narrowing from the inside. A service call for a visual inspection and pressure test can usually confirm it quickly.
