Causes of Smelly Tap Water
If your home tap water has a strange smell, it can be caused by some common reasons. Here are four of the most common reasons:
1. Bacteria in the Water:
Sometimes, bacteria can gradually grow in your home water supply, most probably when it comes from a well or has been sitting in the pipes for too long. These bacteria can produce a smell similar to rotten eggs. However, it is not always harmful, but it can make your water unpleasant to use.
2. Chlorine Levels:
Tap water is usually treated with chlorine to remove germs and make it completely safe to drink. However, if the chlorine level is too high, then your tap water might smell like a swimming pool. This smell is more common in areas with heavily treated water or during certain times of the year.
3. Old Pipes:
Over time, the pipes in your home plumbing system can develop rust or other buildup. This can cause your tap water to smell metallic, musty, or earthy. Moreover, the smell might be even stronger when you first turn on the tap in the morning.
4. Decaying Organic Matter:
Leaves, dirt, and other natural materials can sometimes find their way into your home water supply. As these materials break down, they can give off a musty or muddy smell. Remember this issue is more common in areas with older water systems or after heavy rains.
Best Ways to Treat Smelly Tap Water
If your home tap water smells bad, then don’t worry. There are some of the best ways to treat smelly tap water, depending on the cause. Here are some of the best ways to get rid of it.
1. Flush your Pipes:
Sometimes, water sitting in your pipes for too long can cause a bad smell. To fix this issue, turn on all your home taps and let the water continuously run for a few minutes. This will efficiently flush out any old water and bring in fresh water from the main supply.
2. Clean Your Plumbing System:
If your tap water pipes are old or dirty, then they might be causing a bad smell. To efficiently fix this issue, consider getting your plumbing system cleaned by a professional. They can remove rust, bacteria, and other buildup inside the pipes that might be creating a bad smell.
3. Install a Water Filter:
A water filter can help remove harmful impurities from tap water that causes bad smell. There are multiple types of water filters available such as carbon filters and reverse osmosis systems. These filters can get rid of chlorine, bacteria, or organic matter, making your tap water smell completely fresh and clean.
4. Treat Well-Water:
If you use well water and it smells similar to rotten eggs, then the main problem might be sulfur bacteria. A common solution is to simply add a shock treatment such as chlorine, to the well. This efficiently kills the bacteria and improves the water’s smell. You can also install a specialized filter designed to remove sulfur.
5. Boil your Tap Water:
In case, the smell is minor and temporary, then boiling your tap water can help. This method is especially useful if the smell comes from bacteria or organic materials. Boiling kills germs and improves the water’s taste and smell.
6. Contact Your Water Supplier:
If the smell is directly coming from your main water supply, then you should contact your water supplier. They can test your tap water and let you know if there is an issue with the treatment process or the pipes. They might also recommend solutions for your specific problems.
These methods can help you enjoy fresh-smelling and clean water again. If the problem still persists, don’t hesitate to seek professional help.
