How to Fix / Troubleshooting
Safety first: Rusty water is usually not an immediate safety hazard but indicates corrosion.
- Confirm hot-only: Check if discoloration is only in hot water. If cold also rusts, the issue is with supply piping.
- Flush tank: Drain several gallons from the heater until water runs clearer.
- Inspect anode rod: Turn OFF power/gas, relieve pressure, and remove the anode rod. If heavily consumed, replace with a Rheem-compatible rod.
- Evaluate age: If the heater is near or beyond its expected life and rust persists, plan for tank replacement.
