7 Common Problems For Gas Or Electric Hot Water Heaters And Do It Yourself Solutions (Part 2)

3. Rust Colored Water

Possible Causes:

  • Corrosion inside the tank.
  • Failing sacrificial anode rod (anode rods are designed to dissolve slowly inside the tank to prevent rust).

Possible Repairs:

  • Replace the sacrificial anode rod with a magnesium anode rod. You can find anode rods in your local plumbing or hardware store and they are simple to replace.

4. Rotten Egg Odor

Possible Causes:

  • You could be experiencing bacteria build up in the tank due to a decayed sacrificial anode if you have a hydrogen gas water heater.

Possible Repairs:

  • Flush the water heater using 2 pints of 3% hydrogen peroxide for every 40 gallons of water. Treat the tank as well as run the solution through the water lines. Allow the solution to set in the pipes for at least two hours. There is no need to rinse the solution; it is a non toxic treatment.
  • If flushing does not help the problem, replace the anode with a zinc-alloy anode.
  • If you still experience problems the tank may need to be replaced with a plastic lined tank.

5. Rumbling or Popping Noises

Possible Causes:

  • If you hear sounds similar to boiling water then you may have a buildup of sediment at the bottom of your tank that is causing overheating of the water to occur.

Possible Repairs:

  • Remove the sediment by flushing the tank using the hydrogen peroxide solution as listed above.

6. Whining or High Pitched Squeal (Electric Water Heaters)

Possible Causes:

  • The electrical heating elements may have build up of scale material.

Possible Repairs:

  • Flush the hot water heater using the hydrogen peroxide solution mentioned previously.
  • Remove scale from the water heater tank and the elements.
  • Install a lower watt density heating element. These will offer less electrical wattage per square inch than a standard high wattage element when transferring heat to the water.

7. Leaking Water around the Base of the Water Heater

Possible Causes:

  • Faulty temperature and pressure relief valve.
  • Temperate and pressure valve leaking due to excessive pressure if overheating or stuck.
  • Possible leak from pipes above the water heater unit.
  • Tank leaking due to corrosion.

Possible Repairs:

  • Place a bucket under the overflow pipe and open and flush the temperature and pressure valve to clear any possible debris. If you still encounter leaks, replace the valve.
  • Lower thermostat setting to prevent overheating in the tank.
  • Check for corrosion under the tank through the combustion chamber. If you notice heavy water marks or heavy rusting you will need to replace the hot water heater.
