Common Faucet Water Smells and Their Causes
Understanding why your faucet water smells starts with identifying the type of odor. Each type of smell typically indicates a specific issue:
1. Rotten Egg Smell (Sulfur or Hydrogen Sulfide)
Cause:
This is one of the most common water complaints. A sulfur or rotten egg smell is usually due to hydrogen sulfide gas, a naturally occurring compound found in groundwater.
Potential Sources:
- Bacteria in the drain or pipes
- Water heater buildup
- Well water contamination
2. Musty or Earthy Smell
Cause:
An earthy or moldy smell is often due to algae, mold, or bacteria in your plumbing system or water supply, especially if your home uses well water.
Potential Sources:
- Organic material in the source water
- Plumbing system contamination
- Seasonal changes in municipal water supply
3. Chlorine or Bleach Smell
Cause:
If your tap water smells like a swimming pool, it’s likely due to chlorine used to disinfect municipal water.
Potential Sources:
- Routine municipal water treatment
- Excess chlorine at your home tap
- Infrequent use of plumbing fixtures
4. Metallic Smell (Iron, Copper, Zinc)
Cause:
A metallic taste or smell usually indicates corroding pipes, especially in older homes with iron or copper plumbing.
Potential Sources:
- Old galvanized pipes
- High mineral content in well water
- Low pH causing pipe corrosion
5. Sewage or Decaying Odor
Cause:
This strong, unpleasant smell could be from bacteria buildup in your sink’s drain or plumbing system.
Potential Sources:
- Dirty drains
- Blocked vent pipes
- Sewer line issues
Is Smelly Faucet Water Safe to Drink?
Whether smelly water is safe to drink depends on the cause:
- Chlorine smell: Usually safe but unpleasant.
- Sulfur smell: May not be dangerous in small amounts but can indicate bacterial contamination.
- Metallic smell: Might be safe but could point to high levels of iron or copper, which are problematic long-term.
- Sewage smell: Potentially unsafe — avoid drinking and investigate immediately.
💡 Tip from Cuoll: If you’re unsure, always err on the side of caution. Have your water tested professionally or use a home water testing kit.
Fixes for Smelly Faucet Water
1. Clean the Faucet and Drain
Step-by-step:
- Pour a mixture of baking soda and vinegar into the drain.
- Let it sit for 15–20 minutes.
- Flush with hot water.
- Scrub the faucet aerator with a toothbrush.
2. Flush the Water System
If you haven’t used your taps in a while (like after a vacation), turn on all faucets and let the water run for a few minutes.
3. Install a Water Filter
Using a point-of-use or whole-house water filter can dramatically reduce or eliminate smells.
Types of filters:
- Activated Carbon Filters (good for chlorine and organic odors)
- Reverse Osmosis Systems (excellent for sulfur, metals, and chemicals)
- Sediment Filters (pre-filtering particulates that contribute to odors)

4. Check and Maintain the Water Heater
Sediment and bacteria buildup in water heaters can cause smelly hot water. Flush your water heater at least once a year.
Pro tip: Set the heater temperature to 60°C (140°F) to kill bacteria but avoid scalding.
5. Use Shock Chlorination (For Well Water)
This is a temporary fix for bacterial contamination. Use a professional-grade chlorine solution and follow strict safety protocols, or hire a professional.
How to Prevent Faucet Water Smells
1. Regular Maintenance
- Clean your faucet aerators and drains monthly.
- Flush your plumbing system if water sits idle for long.
2. Invest in a Whole-House Filtration System
These systems ensure that every tap in your home delivers clean, fresh-smelling water.
Benefits:
- Removes chlorine, sediments, sulfur, and metals
- Extends the life of your plumbing
- Improves taste and smell instantly
3. Test Your Water Regularly
Use water testing kits every 6 months or after seasonal changes, especially for homes using well water.
4. Upgrade Old Plumbing
If metallic odors persist, it may be time to replace outdated iron or galvanized steel pipes.
5. Install Faucet-Specific Filters
Install faucet filters on sinks that are frequently used for drinking or cooking. Cuoll offers easy-to-install options that fit most standard faucets.
When to Call a Plumber or Water Specialist
If you’ve tried all DIY methods and your water still smells bad, it’s time to call in a professional. Contact a plumber or water specialist if:
- The smell persists for more than a few days.
- The water is discolored or cloudy.
- You notice a sewage smell (possible serious issue).
- You use well water and haven’t tested it recently.
