Does your tap water have a strong rotten egg odor? If so, you’re not alone. Many Southern California homeowners and business owners experience this unpleasant issue. “Why does my water smell like rotten eggs?” is a common question—and the answer usually ties back to plumbing problems that are best handled by a professional. In this guide from A-1 Performance Rooter & Plumbing, Southern California’s top plumbing experts, we’ll explain why water sometimes smells like rotten eggs, what it means for your pipes and health, and how you can fix the problem fast.
What Causes Your Water to Smell Like Rotten Eggs?
The primary culprit behind that rotten egg smell in tap water is hydrogen sulfide gas. This is a colorless gas that gives off a strong sulfur-like odor. In Southern California areas like Los Angeles, Long Beach, and Orange County, the water supply conditions and plumbing history can make this issue surprisingly common.
Here’s how hydrogen sulfide makes its way into your water:
- Bacterial Growth: Certain non-harmful bacteria react with sulfate in water, producing hydrogen sulfide.
- Reaction in Water Heaters: If you notice the smell only with hot water, it’s often your water heater’s anode rod reacting and creating hydrogen sulfide gas.
- Well Water Issues: Homes with private wells are especially susceptible, but municipal water can also be affected if the plumbing system is outdated or corroded.
Is Water That Smells Like Rotten Eggs Dangerous?
Is water with a rotten egg smell safe? In most cases, the hydrogen sulfide concentration causing the odor isn’t harmful to your health. However, high concentrations can:
- Lead to unpleasant taste and smell in drinking water or cooking water
- Corrode pipes and plumbing fixtures, leading to leaks and expensive repairs
- Stain sinks, toilets, and laundry with black or yellow color
- Indicate bacterial contamination, especially in older homes or those with outdated plumbing in Southern California
Experts agree: if the odor is strong or has appeared suddenly, consult a professional plumber for an inspection to avoid any potential health or plumbing risks.
How Do You Get Rid of Rotten Egg Smell in Water?
Once you notice the rotten egg smell in your water, follow these steps before calling in the experts:
- Determine if it’s hot or cold water: Turn on taps separately. Is the odor only present with hot water? If so, your water heater is the likely source.
- Flush your system: Run water for several minutes. If the smell dissipates, it may have been stagnant water in your pipes, common in lesser-used LA or San Diego homes.
- Clean faucet aerators and showerheads: Bacterial growth can occur here, especially in high-mineral Southern California water.
- Test water quality: Use a home test kit or contact a professional for comprehensive testing, especially if other symptoms like stains, off-taste, or discoloration occur.
If the smell persists, it’s usually a sign you need professional help.

Why Rotten Egg Smells Are Common in Southern California
Southern California’s unique water supply, old infrastructure, and hard water can worsen hydrogen sulfide problems. Cities like Los Angeles, Fullerton, Garden Grove, and Irvine often report these complaints, especially during dry spells when groundwater sources are low.
- Older Pipes: Many LA and Long Beach homes have plumbing over 50 years old, increasing risk of corrosion and bacteria.
- SoCal Water Sources: Municipal supply can combine surface and groundwater, each with different mineral and sulfate levels.
- Hot Climates: Warm weather accelerates bacterial activity in water heaters and pipes.
These local challenges make it especially important to rely on a local expert like A-1 Performance Rooter & Plumbing—your neighborhood specialists in tackling tough odor and plumbing issues.
