There’s nothing worse than turning on the tap and being greeted by a foul odor. If you’ve noticed smelly water coming from your water heater, you’re not alone—it’s a common problem that can make daily routines unpleasant. Ignoring the issue won’t solve it; in fact, it may only get worse. That’s where our expert water heater repair team comes in. We’re ready to diagnose and resolve the problem, ensuring your water is fresh and clean again in no time.
Whether you’re dealing with a new water heater or an ongoing smelly water issue, there are a few common culprits. From bacteria in the tank to a worn-out anode rod, these problems need attention before they make your home’s water an even bigger issue.
Top 5 Reasons for Smelly Water from Your Water Heater
Reason #1: Bacteria in the Tank
One of the most common reasons for smelly water from your water heater is bacteria in the tank. This is especially true if you have well water, which can be more prone to harboring bacteria. When these bacteria start to break down, they produce hydrogen sulfide gas—a chemical compound that smells like rotten eggs.
Not exactly what you want in your morning shower! The warm, moist environment inside your water heater tank is the perfect breeding ground for these odor-causing bacteria, so it’s crucial to keep your tank clean and well-maintained.
Reason #2: The Anode Rod
The sacrificial anode rod in your water heater plays a vital role in preventing corrosion inside the tank. It’s made of magnesium or aluminum, metals that naturally attract corrosive elements in the water, sparing your tank from damage.
But, the downside is that this process can sometimes create a sulfur-like odor, leading to smelly water from your hot water heater. While it’s doing its job, the anode rod can produce that distinctive rotten egg smell, especially if it interacts with bacteria or softened water.
Reason #3: Softened Water
- Positive: Softened water reduces mineral buildup, protecting your plumbing system.
- Negative: When softened water interacts with the anode rod, it can accelerate hydrogen sulfide gas production.
- Tip: If you’re using a water softener and notice a strong odor, you might need to adjust the settings on your softener or replace the anode rod to mitigate the smell.
Reason #4: Sulfate-Reducing Bacteria
- Characteristics: These bacteria thrive in warm, low-oxygen environments, like your water heater.
- Impact: They produce hydrogen sulfide gas, which is responsible for that nasty rotten egg smell.
- Advice: Flushing your water heater regularly and ensuring it’s operating at the correct temperature can help keep these bacteria at bay.
Reason #5: New Water Heater Smelly Water
If you’ve just installed a new water heater and noticed smelly water, don’t panic—it’s not unusual. New water heaters can produce an initial odor as they go through their first few heating cycles. This smell usually fades as the heater breaks in and the water inside gets fully circulated.
But, if the smell persists, it could be a sign of another issue, like those mentioned above, and might require further investigation.
Quick Fixes and Long-Term Solutions
Got smelly water from your water heater? Start by flushing the tank to remove any bacteria or sediment buildup. Simply turn off the heater, drain the water, and refill it.
Another quick fix is replacing the anode rod—opt for an aluminum-zinc rod to reduce odors. These simple steps can often clear up the smell and keep your water fresh.
If the smell lingers after trying DIY solutions, it’s time to call in a professional plumber. Persistent odors could indicate a more serious issue, like a malfunctioning heater or a need for deeper cleaning.
