Water Line Replacement – Lake Grove, Lake Oswego OR
True Flow Plumbing replaces water service lines throughout Lake Grove in Lake Oswego. Homes built in Lake Grove during the 1950s and early 1960s were served by galvanized steel water service lines — the standard of that era, but now 60 to 70 years past installation. Galvanized steel rusts from the inside out: interior deposits narrow the pipe over decades, reducing pressure and eventually releasing rust particles into the water supply. At this age, a galvanized service line that hasn't been replaced isn't a question of whether it fails — it's a question of when and how disruptively.

How We Replace It in Lake Grove
Lake Grove has generally flat to gently rolling terrain that works well for directional drilling. The boring machine pulls the new PEX line underground from meter to house without opening a continuous trench — driveways, walkways, and established landscaping stay intact. Where lot layout, subsurface conditions, or tight access make directional drilling impractical, we use targeted excavation and explain why before starting. Water is restored before we leave and most replacements are completed in a single day.
- Site assessment before committing to installation method
- Directional drilling on most Lake Grove lots
- New PEX service line — rust-proof, 50+ year rated
- City of Lake Oswego permit handled
- Water restored before we leave
- Most replacements completed same day
Frequently Asked Questions
The water in my Lake Grove home sometimes looks slightly orange or brown in the morning. What's causing it?
On a 1950s or 60s Lake Grove home, rust-colored water is almost always the galvanized service line. Rust accumulates inside the pipe overnight when water sits still; the first draw in the morning flushes it through. As the corrosion progresses, the discoloration appears more frequently and more intensely. This is a reliable indicator that the galvanized line is at or past the point where replacement makes sense — both for water quality and because the ongoing corrosion is gradually reducing pressure.
