Richmond water heater causes discolored (rusty or brown) hot water.

Safety first: Discolored water may stain fixtures and laundry—avoid use until cleared.

• Determine source: Check if discoloration occurs only on hot water. If both hot and cold are affected, the issue is likely in the municipal supply or piping.
• Flush heater: Drain and flush the tank until water runs clear. This may need to be repeated.
• Inspect anode rod: Remove and inspect the anode. If it is heavily consumed, replace with a Richmond-compatible anode rod.
• Evaluate tank age: If the heater is old and rust persists, the glass lining may be compromised and replacement of the heater may be the best solution.
