The answer to 'why is my water heater smells bad' is that a rotten egg or sulfur-like odor coming from your water heater is usually caused by bacteria in the tank that produce hydrogen sulfide gas. This is a common issue, especially in areas with high sulfur content in the water.
Other potential causes include a malfunctioning anode rod, mineral buildup, or a problem with the water supply. If the smell is coming from the hot water, it's likely originating in the water heater itself.
Drain the tank completely and flush it with clean water to remove any sediment or buildup that may be causing the odor.
The anode rod helps prevent corrosion in the tank. If it's worn out, replacing it can help eliminate the smell.
If the smell is due to high sulfur content in the water, adding a water softener can help reduce the odor.
To fix a smelly water heater, you can try flushing the tank, replacing the anode rod, or adding a water softener. If the problem persists, you may need to call a professional plumber or HVAC technician.
A smelly water heater is generally not dangerous, but the hydrogen sulfide gas can be toxic in high concentrations. It's important to address the issue promptly to ensure your home's safety.
