Why Does My Water Heater Smell Like Rotten Eggs?

Have you ever noticed an unpleasant rotten egg smell wafting through your Indianapolis area home, only to find it’s coming from your water heater? You’re not alone. The good news is there are easy ways to address it. Let’s learn from the plumbers at Mister Water Heater about what causes this issue and how we can help fix it.

What Causes the Smell?

The notorious rotten egg smell is usually caused by hydrogen sulfide gas, which is often linked with sulfur bacteria that thrive in heated water. These bacteria produce hydrogen sulfide gas when they react with sulfur compounds in the water.

These bacteria are particularly attracted to environments where there’s a good heat source with low amounts of oxygen. That’s why water heaters, especially ones that aren’t flushed or cleaned, can provide a breeding ground for these bacteria.

How Do I Fix It?

There are a few practical ways to address the issue:

1. Routine Maintenance: It’s important to regularly flush your water heater to minimize bacterial growth. This prevents sediment build-up. It can also help extend the life of your water heater and potentially increase the efficiency of your unit.
2. Replace Your Anode Rod: Sometimes, a corroded anode rod can react with bacteria in the water to cause a rotten egg smell. A simple replacement could fix the problem.

When Should I Contact a Professional?

It’s always best to contact a professional to diagnose the problem and repair your water heater. Our trusted plumbers can find the source of the smell and determine the right solution for your unit.
