What causes rusty water from my faucets?

Why Is My Water Rusty or Discolored?

Rusty, discolored water coming from your faucets can be concerning and usually indicates one of these issues:

• ✔ Corroded pipes: Older galvanized steel pipes naturally corrode over time, releasing rust into your water.
• ✔ Water heater corrosion: If rusty water only appears with hot water, your water heater tank likely has internal rust.
• ✔ Municipal water system work: Recent work on water mains can stir up sediment, temporarily causing rusty water.
• ✔ High iron content: Your water source (especially well water) may naturally contain high levels of iron.
• ✔ Corroded water main: Problems with your city's water distribution system can affect water quality.

To determine the source, check if the discoloration affects hot water, cold water, or both. If it's only hot water, your water heater likely needs service or replacement. If it's both hot and cold and persists for more than a day, your home's pipes may be corroding. Rusty water isn't typically a health hazard, but it can stain fixtures and laundry, taste metallic, and indicate bigger plumbing problems that need addressing.
