Rust Stains & Discoloration

Explore filtration systems for rust-colored stains and water discoloration associated with iron, manganese, sediment, or corroding plumbing. Compare sediment filtration, iron treatment, and whole-house systems by water-test results, micron rating, media, flow rate, capacity, and backwash or replacement needs. Identifying the source helps prevent choosing the wrong treatment method.
