Most people expect their tap water to be clean, fresh, and safe to drink. So when you turn on the faucet and notice a strange smell, it can be unsettling. Many homeowners look for a professional plumber in New Castle when these issues appear because odors in tap water can be a sign of problems in your plumbing system or water supply. Companies like Mr. Rooter Plumbing of Youngstown often explain that bad smells can come from a mix of natural causes and plumbing issues that need attention. Understanding the source of these odors can help you know whether it is a quick fix or something that requires professional service.
Why Does Tap Water Sometimes Smell?

Tap water can pick up odors from the ground, pipes, or water heaters. Sometimes, it is harmless, like minerals that naturally occur in water. Other times, it can signal bacteria or chemical buildup. Knowing the difference can help you decide whether to call a professional or try a simple solution at home.
Rotten Egg Smell
One of the most common water complaints is a rotten egg smell. This odor usually comes from hydrogen sulfide gas. It can form naturally in groundwater or develop inside your water heater if bacteria are present. The scent is strong and unpleasant, and it can make your whole kitchen or bathroom feel unclean. A plumber in New Castle may check your water heater or pipes to see if bacterial growth is the problem.
Musty or Moldy Odors
If your water smells musty, it may be a sign of organic matter in the system. This can happen when leaves, soil, or decaying plants mix into the water supply. Sometimes, old or corroded pipes can also cause this problem. Cleaning filters or replacing aging pipes may solve the issue. Mr. Rooter Plumbing of Youngstown often recommends checking both indoor plumbing and the municipal supply to find the source.
Chlorine-Like Smell
Cities often add chlorine to tap water to kill bacteria and keep it safe. In small amounts, this is not harmful. But if the chlorine smell is very strong, it can be unpleasant and make you avoid drinking your tap water. Running the faucet for a few minutes reduces the smell. If it does not improve, it may point to a water treatment issue, which a professional should inspect.
Metallic Taste or Smell
Water that tastes or smells like metal often comes from old pipes. Rust, iron, or copper can leach into the water supply. While this may not always be dangerous, high levels of metals can cause health concerns. Replacing old plumbing is the most common fix. Mr. Rooter Plumbing of Youngstown has helped many homeowners replace aging pipes to restore clean, fresh water.
Sewage or Dirty Smell

A sewage-like smell is more serious and may point to contamination. Broken sewer lines, cross-connections, or clogged vents can cause foul odors to travel back into your home’s water. This problem should not be ignored. If you notice this type of smell, it is smart to stop using the water until a professional can check it.
Water Heater Problems
Sometimes the problem is not with your main water supply but with your water heater. If the smell occurs only when you use hot water, the heater may need to be flushed. Sediment buildup or bacteria inside the tank can create strong odors. Regular maintenance and flushing the heater can prevent this issue. Professionals often suggest replacing the anode rod, which can also help reduce unwanted smells.
When to Call a Professional
While some odors may be harmless or temporary, others signal bigger problems. If the smell persists after running the tap or is particularly strong and unpleasant, it is best to call a professional. Water quality is directly tied to your health, and ignoring the problem can cause damage to your plumbing system or even illness.
How a Plumber Can Help
A professional inspection can identify whether the problem comes from your pipes, water heater, or the supply line. Specialized testing may be needed to check for bacteria, chemicals, or metal levels. With proper tools and knowledge, professionals can provide lasting solutions that go beyond temporary fixes. Mr. Rooter Plumbing of Youngstown is often called on to solve these problems for local homeowners. Their team can perform full inspections, replace old pipes, clean water heaters, and ensure your water is safe to drink.
