Why Does My Water Heater Smell Bad?

Your home features all the modern comforts you expect, including indoor plumbing and water heating. Your tap water should come out clean and clear, so if you notice a foul odor issuing from the tap, you’re right to worry! Different situations may cause the smell to resemble dirt, rotten eggs, or even sewage. Here are three possible reasons why your water heater smells bad and when to schedule water heater repair.

Bacteria in the Drain

Problem: If your sink smells like sewage every time you turn on the faucet, the water heater might not be to blame. Instead, bacteria from food, soap, and other organic materials could be living in the drain. When water comes pouring in, gas rises from the sink, making it seem like the water itself smells.

Solution: Kill the odor-causing bacteria living in the drain by dumping chlorine bleach into the sink and down the basin overflow if your sink has one. Maintain a fresh scent in your kitchen sink by running citrus peels and a squirt of soap through the garbage disposal.

Bacteria in the Water Heater

Problem: Bacteria sometimes thrive in tank water heaters, producing hydrogen sulfide as they multiply. Even though it won’t hurt you, this smelly gas is responsible for the rotten egg odor you detect every time you run hot water.

Solution: More bacteria grow if you keep the water heater at a low temperature or leave the plumbing untouched while you’re out of town. You can flush the tank by turning up the temperature for 24 hours and running hot water from all the taps. From now on, set the temperature no lower than 120 degrees to prevent future bacterial growth.

Bacteria Reacting with the Anode Rod

Problem: Water heaters come with an anode rod, a sacrificial piece of metal that attracts corrosive buildup to protect the tank from rusting out. Aluminum and magnesium are common anode rod materials, but they react with bacteria that exist in some tanks to produce the dreaded hydrogen sulfide gas.

Solution: Replace the standard magnesium or aluminum anode rod with an aluminum/zinc alloy.
