Brown water is almost always caused by iron or manganese in your water supply. These minerals are totally natural—they’re in the ground, in rocks, and even in your breakfast cereal.
When these minerals get agitated, they oxidize. That’s a fancy way of saying they rust, just like an old nail left out in the rain. The result? That tea-like tint that makes you wonder if you’re about to shower in a muddy puddle.
Think of it as your plumbing’s way of saying, “Hey, I’ve got some character!”.
Where Does the Rust Actually Come From?
If you live in an older house or an area with aging infrastructure, your pipes might be made of galvanized steel or cast iron. Over decades, water slowly wears them down from the inside.
Those tiny flakes of rust? They’re just souvenirs from your pipe’s long, hard life. It’s like finding a relic in your basement.
Newer homes with copper or PEX pipes are way less likely to have this issue—unless the city water main gets a surprise shake-up.
