A metallic taste or reddish-brown tint in your water is often caused by iron. It can come from natural minerals in well water, corrosion of old pipes, or rust particles from your plumbing or water supply. While small amounts of iron are not usually harmful, they can stain laundry and fixtures, and make water taste unpleasant. Testing your water will confirm the cause and help determine if an iron filter or other treatment is needed.
