Water heater malfunction: unmasking the root of foul water smell

Water heaters are essential appliances in our homes, providing us with hot water for showers, dishes, and other daily tasks. However, sometimes water heaters can develop problems that can affect the quality of our water, including causing it to smell. In this blog post, we will explore the question: “Can water heaters make water smell?” We will discuss the potential causes of smelly water from water heaters and provide tips on how to troubleshoot and resolve the issue.

Causes of Smelly Water from Water Heaters

There are several reasons why water heaters can make water smell. Some of the most common causes include:

1. Bacteria Growth

Bacteria can thrive in warm, moist environments, such as the inside of a water heater. If the water heater is not properly maintained, bacteria can build up and produce foul-smelling gases.

2. Anode Rod Corrosion

The anode rod is a sacrificial component in the water heater that helps to protect the tank from corrosion. Over time, the anode rod can corrode and release metal ions into the water, which can cause a metallic smell.

3. Sediment Buildup

Sediment from the water supply can accumulate at the bottom of the water heater tank. As the sediment builds up, it can release gases that can cause water to smell.

4. Mineral Deposits

Minerals in the water supply can also deposit on the inside of the water heater tank. These deposits can release gases that can cause water to smell.

Troubleshooting Smelly Water from Water Heaters

If you notice that your water smells, there are several steps you can take to troubleshoot the problem:

1. Check the Water Heater Temperature

The ideal temperature for a water heater is between 120 and 140 degrees Fahrenheit. If the water heater is set too high, it can promote bacteria growth and lead to smelly water.

2. Flush the Water Heater

Flushing the water heater can help to remove sediment and mineral deposits that may be contributing to the smell. To flush the water heater, follow these steps:

• Turn off the water supply to the water heater.
• Attach a hose to the drain valve at the bottom of the water heater.
• Open the drain valve and allow the water to flow out until it runs clear.
• Close the drain valve and turn the water supply back on.

3. Replace the Anode Rod

If the anode rod is corroded, it should be replaced. Replacing the anode rod is a relatively simple task that can be done by a homeowner with basic plumbing skills.

4. Call a Plumber

If you have tried the troubleshooting steps above and the water still smells, it is best to call a plumber. A plumber can diagnose the problem and recommend the best course of action.

Summary: Unraveling the Mystery of Smelly Water from Water Heaters

Water heaters can make water smell due to various factors, including bacteria growth, anode rod corrosion, sediment buildup, and mineral deposits. By understanding the causes of smelly water from water heaters, homeowners can take steps to troubleshoot and resolve the issue. If the problem persists, it is advisable to seek professional assistance from a plumber.

Questions We Hear a Lot

Q: Why does my water heater water smell like rotten eggs?

A: A rotten egg smell in water can indicate the presence of bacteria that produce hydrogen sulfide gas. This can be caused by a buildup of sediment or organic matter in the water heater tank.

Q: What causes a metallic smell in water from a water heater?

A: A metallic smell in water from a water heater is usually caused by corrosion of the anode rod. The anode rod is designed to protect the water heater tank from corrosion, but over time it can corrode and release metal ions into the water.

Q: Can I drink water that smells from my water heater?

A: It is not recommended to drink water that smells from your water heater. The smell may indicate the presence of bacteria or other contaminants that can be harmful to your health.
