Water Line Replacement – King City, OR
True Flow Plumbing replaces water service lines throughout King City, Oregon. King City's 1970s copper water service lines are now 45 to 55 years old and in the range where Portland's soft, slightly acidic water chemistry has been causing interior pitting for decades. Blue-green staining at sinks, toilets, and tubs is the visible sign — copper dissolving out of the service line into your water supply. Pinhole leaks follow. King City's consistent single-era build means water line pitting is hitting the city's homes on a similar timeline; if your neighbors are seeing blue-green staining, your line is likely in the same condition. We replace with PEX — immune to soft water corrosion, rated 50-plus years, and installed with a City of King City permit on every job.
