What to Do If Your Water Has a Rusty or Metallic Smell
If you’ve noticed a rusty or metallic smell coming from your tap water, you’re not alone. Many homeowners face this issue, and while it can be unsettling, it’s often a sign of an underlying problem with your plumbing or water supply. The good news is that this problem can usually be resolved with the right steps. In this blog post, we’ll discuss the common causes of a rusty or metallic smell in your water, the potential health impacts, and the best actions you can take to fix the issue.
What Causes a Rusty or Metallic Smell in Water?
Rusty or metallic odors in water usually stem from specific sources, each requiring its own solution. Let’s look at the common causes in detail:
1. Corroded Pipes
One of the primary reasons for a metallic smell is corroded pipes. Over time, especially in older homes, pipes can rust, especially if they are made from iron or steel. This corrosion can result in particles of iron and other metals leaching into the water, creating a metallic taste and odor. If you live in an older home, this may be a likely cause of the issue.
How to tell if your pipes are corroded:
- Rust-colored or discolored water from your taps.
- A noticeable metallic taste in your drinking water.
- Water that appears cloudy or has a reddish-brown tint.
If you suspect that your plumbing is the problem, it’s important to address it sooner rather than later. Corrosion can lead to leaks and more serious water damage if not properly dealt with.
2. High Iron Content in Water
Water with naturally high levels of iron often develops a rusty or metallic smell. This is particularly common in areas with hard water, where minerals like iron, magnesium, and calcium are abundant. While iron in your water isn’t typically harmful, it can cause unpleasant smells and may stain laundry, dishes, and even your bathroom fixtures.
How to test for high iron content:
- Use a water testing kit to measure the levels of iron in your water.
- Contact your local water provider to see if they have data on the iron content in the public water supply.
If you have high iron content, you may notice it more in the hot water, as hot water can dissolve more minerals. An iron filtration system can be installed to reduce these levels.
3. Problems with Your Water Heater
Your water heater could be the culprit if the issue is only with hot water. Over time, mineral deposits can build up inside the water heater, especially in areas with hard water. These deposits may cause a metallic or sulfur-like odor to develop in the water.
Another common issue with water heaters is the anode rod. The anode rod is designed to prevent corrosion in the tank, but if it’s worn out or ineffective, it can lead to the development of smelly water.
Signs your water heater may be the issue:
- Metallic or sulfur-like odors only when using hot water.
- Strange smells that worsen after the water has been sitting for a while.
- Low water temperature or inconsistent heating.
To resolve this issue, your water heater may need to be flushed, cleaned, or the anode rod replaced. If the problem persists, it may be time to replace the water heater entirely.
4. Well Water Contamination
If you rely on well water, high levels of iron and other minerals could be the cause of the smell. Well water can also be contaminated with sulfur, bacteria, or organic matter, leading to foul odors. In addition to high iron levels, other contaminants could contribute to a metallic or rust-like smell.
How to handle well water issues:
- Test your well water for various contaminants, including iron, sulfur, and bacteria.
- Consider installing a water filtration system designed for well water.
- Regularly disinfect the well to ensure its cleanliness and maintain good water quality.
5. Municipal Water Supply Issues
In some cases, municipal water supply issues can cause a rusty or metallic smell. While rare, water main breaks or repairs can introduce rust into the water system, leading to temporary odors and discoloration. If the issue is limited to a specific time frame or after water main work, it may resolve on its own once the system stabilizes.
What to do:
- Contact your local water utility to check if there have been any issues in the water supply, such as repairs or maintenance.
- If the problem is widespread, they should be able to provide guidance on when the issue will be resolved.
Health Considerations
While a rusty or metallic smell in your water is unpleasant, it’s typically not harmful. However, iron levels above a certain threshold can stain teeth and skin, and long-term exposure to high levels of certain metals, like copper, can lead to health issues. If you suspect high levels of heavy metals or other contaminants, consider having your water tested by a certified lab to ensure your water quality is safe.
What You Can Do to Fix the Problem
Now that we’ve explored the causes of a rusty or metallic smell, here’s what you can do to resolve the issue:
1. Flush Your Plumbing System
If you have corroded pipes or sediment buildup in your plumbing, flushing the system might help clear out any debris. Run cold water through all of your faucets for several minutes to flush out any iron or rust particles that might be lingering.
How to flush your plumbing:
- Start with the faucet farthest from your water supply, typically a bathroom or kitchen sink.
- Run the water for several minutes to help clear out any rust or sediment.
- Repeat with other faucets throughout your home.
2. Install a Water Filtration System
Installing a whole-house water filtration system designed to remove iron and other minerals can significantly improve the smell and taste of your water. There are various filtration options available, including reverse osmosis and iron filtration systems. These filters can remove iron, sulfur, and other contaminants, leaving your water smelling fresh and clean.
Consider installing these types of systems:
- Iron filter systems: Specifically designed to remove high levels of iron.
- Reverse osmosis filters: Effective at removing a wide range of contaminants, including iron.
- Activated carbon filters: Great for removing chlorine, odors, and sediment.
3. Flush and Clean Your Water Heater
If your water heater is the source of the problem, try flushing it to remove any sediment buildup. If that doesn’t work, consider replacing the anode rod, which could be contributing to the metallic smell. For long-term solutions, consider replacing your water heater if it’s old or inefficient.
Steps to flush your water heater:
- Turn off the power to the water heater.
- Attach a hose to the drain valve at the bottom of the tank.
- Open the valve to let the water flow out and flush the sediment.
- Once the tank is empty, close the valve and refill the tank.
4. Call a Professional Plumber
If the issue persists, or you’re unsure about the source, it’s a good idea to consult a professional plumber. A plumber can inspect your plumbing system, check for any corrosion or rust, and recommend the best course of action.
When to call a plumber:
- If the water smells bad consistently or worsens over time.
- If you notice rust-colored or discolored water.
- If you’re unable to identify the cause of the smell or fix the problem on your own.
Conclusion
A rusty or metallic smell in your water is a problem that can often be resolved with a little attention and care. Whether the issue is caused by corroded pipes, high iron content, or a malfunctioning water heater, addressing the root cause can improve the quality of your water. If you’re unsure about the source of the issue or need professional assistance, don’t hesitate to contact a trusted plumber. Clean, fresh water is essential to your home, and taking care of this problem early can save you from larger, costlier issues down the road.
