Water Treatment & Softeners in Portland, OR
Portland water-treatment contractors in this directory serve homes on Portland Water Bureau (Bull Run watershed water, very soft at 1-2 grains) and surrounding Multnomah County well-water properties. Most Portland tap-water issues are aesthetic (chlorine taste) rather than hardness. Under-sink RO at $400-$900 installed handles drinking water needs. Whole-home softeners are rarely needed for city water.
Portland Bull Run water is among the softest municipal water in the US (1-2 grains). Older Portland homes with lead service lines or galvanized pipes benefit from NSF-53 lead-rated point-of-use filters. Private wells in surrounding rural Multnomah County may need iron filtration and softening.
Frequently Asked Questions
