Fishy Smell in Your Water? Find Out Why and Fix It

    why does my water smell like fish

    Water is essential for life, and its quality plays a big role in our health. So, when your water smells like fish, it can be concerning. Understanding the reason behind this smell is important to make sure your water is safe to drink. Understand why your water might smell fishy, how to figure out the cause, and what you can do to fix it.

    Why Does Your Water Smell Like Fish?

    A fishy odor coming from your tap or filtered water can be unpleasant. The main reasons for this odor include:

    • Organic Materials: Natural materials, like decaying plants or algae, can get into your water, causing it to smell bad.
    • Metals: Certain metals, like barium and cadmium, might enter your water system and create a fishy smell. The Environmental Protection Agency (EPA) regulates these metals to ensure they remain below harmful levels in public water systems.
    • Chloramine: This chemical is a mix of chlorine and ammonia used to treat city water. Sometimes, it leaves a strange odor.
    • Algae Blooms: During certain seasons, algae can grow in lakes or reservoirs, which might make your water smell funny.

    Identifying the Source of the Smell

    If you want to know why your water smells like fish, you first need to figure out where the smell is coming from. Is it in the water itself, or could it be your plumbing?

    Tap Water vs. Drain Smell Test

    A quick and easy way to check if the smell is coming from your water or the drain is by doing a “sniff test.” Here’s how:

    • Fill a glass with tap water.
    • Take the glass to another room, away from the sink.
    • Swirl the water in the glass gently.
    • Smell the water.

    If the water smells fine in another room, the issue might be with your drain, not the water itself. Decaying organic material in your sink or pipes can cause odors that make it seem like the water smells bad.

    Checking for Algal Blooms

    If you live near a lake or reservoir, algae could be the problem. During warmer months, algae growth tends to increase, which can lead to a fishy smell in the water. If you think algae might be the cause, contact your local water supplier to confirm whether algal blooms are affecting your water.

    How Do You Get Rid of the Fishy Smell in Water?

    If your water smells like fish and you want to get rid of the odor, there are several efficient solutions you can try. Here are some ways to tackle the issue and ensure your water is fresh and safe to drink:

    1. Replace Your Water Filters

    If your filtered water smells like fish, replacing the filter is often the simplest solution. Over time, filters can become clogged or unclean, resulting in unpleasant odors. To keep your water smelling fresh, follow the manufacturer’s replacement schedule.

    2. Flush Your Plumbing System

    If the fishy smell seems to be coming from your plumbing, you can flush your pipes by running hot water for several minutes. This can help eliminate any buildup of bacteria or organic materials that might be causing the odor in your tap water.

    3. Install a Water Filtration System

    A whole-house water filtration system may successfully remove toxins from your entire home’s water supply. If your tap water smells like fish due to metals or other impurities, these systems can filter out chlorine, heavy metals, and other substances that contribute to unpleasant odors.

    4. Use Activated Carbon Filters

    Activated carbon filters are effective at removing odors, particularly the fishy smell in water. They work by trapping contaminants and preventing them from entering your drinking water, making your water taste and smell better.

    5. Treat Well Water

    If you rely on well water, regular testing and treatment are important. Well water can readily get contaminated with bacteria and metals, resulting in unpleasant odors. Consider using filtration systems or disinfectants to keep your well water clean and odor-free.

    6. Install a Water Softening System

    If your water has high levels of metals like barium, installing a water-softening system can help. These systems remove minerals and metals that contribute to unpleasant smells, improving the overall quality of your water.

    7. Contact Your Local Water Supplier

    If your tap water smells like fish, it’s a good idea to reach out to your local water supplier. They can provide information on any potential algal blooms or other issues affecting the water supply in your area.

    8. Check for Plumbing Issues

    If the fishy smell only comes from certain faucets, there might be a plumbing issue, such as decaying organic material in the pipes. Hiring a plumber to evaluate your plumbing system might help you identify and resolve the issue.

    9. Use a Water Purification System

    If you’re looking for a more robust solution, consider installing a water purification system. These systems can eliminate a variety of impurities that may be causing your water to smell like fish, resulting in cleaner, fresher water.

    10. Regularly Maintain Your Plumbing

    Keeping your plumbing well-maintained can help prevent odors from developing in the first place. Regularly clean your drains and pipes to remove any organic buildup that could lead to unpleasant smells, ensuring your water stays fresh and safe to drink.

    Preventing Fishy Odors in Water

    Preventing your water from smelling like fish is all about maintenance. Here are some tips to avoid the issue:

    • Test your water regularly, especially if you use well water. Regular testing can help you catch any contaminants early.
    • Change your water filters regularly to prevent bacterial buildup.
    • Flush your plumbing system every now and again to get rid of any stagnant water or dirt.
    • Maintain your water system by ensuring that your well is properly sealed to avoid contamination.

    Know How To Fix the Water That Smells Like Fish

You can try replacing filters, flushing your plumbing, or installing a water filtration system. Regular maintenance and testing can also prevent these smells in the future. By taking these steps, you can keep your water clean and safe to drink. If the problem continues, reach out to your local water supplier for help.
