Iron in water

Iron is common in well water. It leaves orange or brown stains and can give water a metallic taste.

Signs you may have it

  • Orange or brown stains in sinks, toilets and laundry
  • Metallic taste
  • Water that looks clear but stains after it sits

How it's fixed

Iron comes in different forms, and the right filter depends on which form you have and how much. We test first, then design the treatment, often as part of a well system.

Why testing matters

A softener alone can handle small amounts of one form of iron but can be fouled by more. Guessing usually means buying the wrong equipment.

Common questions

I'm on city water and see orange stains. Is it iron?

It can be from old pipes or the water heater. The free test and a look at your plumbing help find the source.

More questions

Not sure what you need? The water test is free.

We test your water at the tap, check your plumbing and tell you what fits, with no obligation to buy.

Results depend on your water, household use and maintenance. Any performance or certification claim applies only to the specific model in your written quote. Field water tests help choose equipment; they don't show whether water is safe to drink.
