Identify if problem is occurring in cold or hot water.
If rusty water appears in the cold water only, flush cold water internally until water clears. If problem persists, contact the City of Aurora Water Production Division at 630-256-3250.
If rusty water appears in the hot water only, it may be from rusty cold water that filled the water heater while using hot water simultaneously when cold supply was discolored. Or, accumulated rust sediment in the water heater is coming through but cold water is clear. In either case it may be necessary to drain and/or flush water heater if problem continues.
