Why Does My Bathroom Faucet Water Smell Like Rotten Eggs?

If you've ever turned on your bathroom faucet and been greeted by the pungent odor of rotten eggs, you're not alone. This common problem can be both unpleasant and worrisome, but it's usually not a sign of anything serious.

### Bacterial Growth

The most common cause of rotten egg smell in faucet water is the presence of bacteria. These bacteria, which thrive in warm, moist environments, feed on the organic matter found in water pipes. As they digest this matter, they produce hydrogen sulfide gas, which gives water its characteristic rotten egg smell.

### Corroded Pipes

Another potential cause of rotten egg smell is corroded pipes. When metal pipes corrode, they release metal ions into the water. These ions can react with hydrogen sulfide gas to create even more of the gas, intensifying the smell.

### Water Heaters

Water heaters can also contribute to rotten egg smell in faucet water. If the water heater's anode rod, which is designed to prevent corrosion, fails or becomes depleted, it can allow the water to corrode the tank. This corrosion can lead to the release of hydrogen sulfide gas.

### How to Fix the Smell

In most cases, the rotten egg smell in faucet water can be eliminated by addressing the underlying cause.

Bacterial growth:

Flush your faucets regularly with hot water to prevent bacteria from building up. You can also use a bleach solution (1/2 cup bleach per gallon of water) to disinfect the faucets and pipes. *

Corroded pipes:

Replacing corroded pipes is the best long-term solution to this problem. *

Water heaters:

If the anode rod in your water heater has failed, it should be replaced by a qualified plumber. ### When to Call a Plumber

If you've tried the above solutions and the rotten egg smell persists, it's best to call a plumber. The plumber can inspect your plumbing system and identify any underlying problems that may need to be addressed.
