The causes of water heater smell

To understand the causes of water heater smell, let’s dive into two sub-sections: the rotten egg smell, caused by hydrogen sulfide gas and sulfate-reducing bacteria, and the sulfur smell, which is a result of the presence of sulfur bacteria. By exploring these causes, we can identify the sources of the unpleasant odors coming from your water heater and take appropriate steps to eliminate them.

Rotten egg smell from water heater: Hydrogen sulfide gas and sulfate-reducing bacteria

A nasty odor of rotten eggs coming from your water heater? It’s likely due to hydrogen sulfide gas and sulfate-reducing bacteria. These sulfur compounds are found in water. Plus, magnesium or aluminum anode rods inside corrode, letting out the gas. This gas gives off the distinctive smell. Also, sulfate-reducing bacteria love the warmth of the heater and contribute to the stench.

To tackle this problem, flush and clean the heater regularly. This removes sediment that may breed bacteria. Consider getting a zinc or aluminum anode rod instead of a magnesium one too, as it may reduce the gas production.

Know that while it’s harmless, it may hint at water quality or plumbing issues. If you sense it often, or if you have discolored water or a metallic taste, consult a plumber.

15% of US households have hydrogen sulfide gas in their water supply says The Water Quality Association (WQA). So, it’s important to understand and deal with the causes of the smell in the water heater for clean water.

Sulfur smell from water heater: Presence of sulfur bacteria

Solve the mystery of the smelly water heater in 5 simple steps!

  1. Investigate: Check if the smell is only in hot water or both hot and cold. If only hot, it’s likely sulfur bacteria.
  2. Flush: Turn off power to the heater. Connect a hose to the drain valve at the bottom of the tank. Place the other end outside/in a drain. Open all hot water faucets. Let the tank drain completely.
  3. Clean/Disinfect: Close all faucets and fill up the tank with fresh water. Add hydrogen peroxide/chlorine bleach as instructed. Let sit for several hours, then drain.
  4. Rinse: Flush the system by filling up the tank with fresh water. Let it run through all faucets until no chlorine/hydrogen peroxide remains.
  5. Prevent: Install a chlorine injection system or an anode rod made of aluminum-zinc alloy.
