Water Line Replacement – Murrayhill, Beaverton OR
True Flow Plumbing replaces water service lines throughout Murrayhill in southwest Beaverton. Early Murrayhill construction from the late 1980s and early 1990s used copper water service lines — standard for that era. Portland metro's soft, slightly acidic water chemistry causes gradual pitting in copper over decades, leading to pinhole leaks that start small and often go undetected in wall cavities or underground until damage is already done. On copper service lines now 25 to 35 years old, the right answer when problems start is full replacement with PEX — a material that's immune to soft water pitting and built for the next 50-plus years.
Copper Service Lines in Early Murrayhill Construction
Murrayhill's planned build-out ran from the late 1980s through the 1990s. Homes from the earlier phases were built with copper service lines; later phases increasingly used PEX as it became the industry standard in the late 1990s. If your Murrayhill home is from the early 1990s or before, copper is likely what runs from the meter to the house. Portland's water chemistry — soft and slightly acidic — works on copper pipe walls over time, creating microscopic pits that deepen year over year. At 25 to 35 years, early Murrayhill copper is in the window where pinhole leaks become increasingly likely.

Frequently Asked Questions
I had a pinhole repaired in my Murrayhill copper line last year. Do I need to replace the whole line?
A pinhole patch fixes that spot and leaves the rest of the line at the same stage of pitting that produced it. On 30-year-old copper in Portland's soft water environment, additional pinholes are likely to develop on the same timeline. Whether to patch or replace depends on how far along the overall pitting is — we can assess the line and give you an honest answer on whether another repair buys meaningful time or whether full replacement makes more sense at this stage.
