Why Does My Well Water Smell or Stain?
A rotten-egg smell is usually sulfur (hydrogen sulfide) or sulfur bacteria; rusty or orange staining is iron, and black specks or staining are manganese — all common in Willamette Valley well water. Most are water-quality issues fixed with the right treatment. If the smell is only in your hot water, it usually points to the water heater, not the well.

What's Usually Causing It?
Ranked from most to least common.
Iron — rusty / orange staining
Very common locally. Stains fixtures, tubs, and laundry; gives water a metallic taste.
Sulfur / hydrogen sulfide
The rotten-egg smell. Sometimes seasonal as groundwater chemistry shifts.
Manganese
Black staining or specks, often paired with iron. Same family of fix.
Sulfur or iron bacteria
Living biofilm in the well or plumbing — slimy buildup, intermittent smells.
Water-heater anode reaction
Smell ONLY in the hot side usually means the water heater, not your well.
What Can I Safely Check First?
Check whether it's all taps or hot-only (hot-only usually means the water heater, which we can confirm). Note the color: orange = iron, black = manganese. This isn't something to just live with — and clear-looking water isn't proof it's clean: arsenic and nitrate, both documented in Willamette Valley groundwater, are odorless and tasteless. We start with a water test (free for well owners), then match treatment — iron filter, softener, UV, or a combined system — to what the test actually shows.
Stop at surface checks. The pressure switch, 220V wiring, and pulling a pump carry high pressure and dangerous voltage — leave those to a licensed pro.
When Should I Call Right Away?
Any of these means stop troubleshooting and call.
Rotten-egg smell from every tap
Sulfur in the well, not just the water heater.
Slimy buildup in tanks or fixtures
Signs of sulfur or iron bacteria in the well or plumbing.
Orange or black staining that keeps returning
Iron or manganese — worth testing before choosing treatment.
Any change in smell, color or taste
Clear-looking water isn't proof it's clean, so test it.
No water right now? We treat that as an emergency.

What Will It Cost?
Depends entirely on what the test finds. A single-issue filter (iron or sulfur) is modest. A whole-home multi-stage system with UV is more. We test first, then quote firm — no guessing.

What Do Oregon Neighbors Say?
“I got estimates from two other companies and learned a lot. Shayne came out and reviewed my situation himself — decades of experience, clearly knows his stuff. They use the highest-quality equipment.”
“I had a deep well pump failure and they made me a priority — out to assess within an hour, and a new pump, pipes, and controller installed by the next day.”
“On time for every appointment, finished faster than expected, and credited me for parts they didn't use. We were only without water about 5 hours while they replaced our pump and pressure tank.”
