Why is the water from my heater rusty or discolored?

If the water from your heater is rusty or discolored, it’s a sign of corrosion or sediment buildup in the tank. While it may not always be harmful, rusty water can stain clothes, dishes, and fixtures, and it’s often a sign that your water heater needs attention. At RepairKE, we help Nairobi residents diagnose and fix issues causing discolored water from their water heaters.

Common Causes of Rusty or Discolored Water

Why Is My Water Rusty?

The most common cause of rusty water from a water heater is a corroded anode rod. The anode rod is a sacrificial component designed to attract corrosion and protect the tank. Over time, the rod corrodes and can flake off, causing rusty water. If the anode rod is completely corroded, the tank itself may start to rust, leading to discolored water.

How to Fix Rusty or Discolored Water

1. Replace the Anode Rod
   • Inspect the anode rod every 2–3 years. If it’s heavily corroded (less than 6 inches of the core wire visible), replace it.
2. Flush the Tank
   • Sediment buildup can cause discolored water. Flush the tank annually to remove sediment.
3. Inspect the Tank
   • If the tank itself is corroded, it may need replacement. A professional technician can inspect the tank and recommend the best course of action.
4. Check Your Pipes
   • If the rusty water is coming from all taps (hot and cold), the issue may be with your galvanized pipes. Consider replacing them with copper or PEX pipes.
5. Test the Water Supply
   • If the rusty water is only coming from the hot taps, the issue is likely with the water heater. If it’s coming from both hot and cold taps, the problem may be with your water supply.

When to Call a Professional

If rusty or discolored water persists after replacing the anode rod and flushing the tank, contact RepairKE. Our technicians can:

• Inspect the tank for internal corrosion.
• Test the water supply for high iron content.
• Recommend a replacement if the water heater is beyond repair.

Preventing Rusty Water in the Future

• Replace the anode rod every 2–3 years or when it’s significantly corroded.
• Flush the tank annually to remove sediment and prevent corrosion.
• Install a water softener if you have hard water to reduce mineral buildup.
• Use dielectric unions when connecting the water heater to copper pipes to prevent galvanic corrosion.
