Why Does My Tap Water Taste Bad? Common Causes & Fixes

Does your tap water taste like soap? The subject of water taste can be, well…subjective. After all, each individual has his or her specific palate for sensing flavors. But there are certain instances when water undeniably has a certain unpleasant flavor.

The question is — is this ok, or is this something you should worry about? Let’s take a look at some (mostly) well-known facts…

And this is due to a number of local factors, including but not limited to the source of water in your [dealer info=”location”] home, its distribution system, construction of pipes, fixtures in your home, weather/climate, surrounding businesses/industries, and the natural topography of the area your home sits upon.

According to the EPA, about 15% of the U.S. population uses well water. The rest are hooked up to municipal systems. Whereas most well water is ground water below the surface, municipalities can take their water from a number of sources, including rivers and lakes. The long journey from these sources — through a treatment plant, underground through pipes, into your home and thru your tap provide a lot of room for variables. Anything the water contacts could affect its perceived taste or smell.

Tap water can taste bad for a few different reasons. In most cases, the issue comes down to minerals, disinfectants, or changes in your local water supply. Even small shifts in water treatment or source can affect how your water tastes from one day to the next.

Different tastes often point to different causes, which is why identifying the flavor is the first step toward solving the problem. Let’s take a look at some of the most common flavors of tap water, where its origins may be, and what you can do if you find it mildly annoying to intolerable:

A soapy taste in water is one of the more unusual complaints, but it does happen. This is often linked to higher alkalinity levels or the way softened water interacts with soap residue on dishes and glassware. In some cases, leftover detergent in your dishwasher or sink can make water seem like it has a slick or soapy feel.

While this type of taste is typically not a health concern, it can make water difficult to drink and may indicate that your water chemistry is out of balance.

If your water smells or tastes like a swimming pool, chlorine is usually the reason. Municipal water systems use chlorine or chloramine to disinfect water and keep it safe as it travels to your home.

In areas like Southern California, this taste can become more noticeable at certain times of the year. Warmer temperatures, maintenance work, or seasonal changes in water demand can all increase the amount of disinfectant in the system.

Chlorine is effective at killing bacteria, but it can leave behind a strong taste that many people find unpleasant.

A metallic taste often points to minerals such as iron, manganese, or even copper. These can come from natural sources in the water supply or from corrosion inside your home’s plumbing.

You might also notice staining in sinks or on fixtures if iron or manganese levels are elevated. While small amounts are generally not harmful, they can significantly affect the flavor of your water.

Salty-tasting water is a common concern and can have several causes. It may be related to naturally occurring minerals in groundwater, but it is also frequently connected to water softeners.

If a softener is not set correctly or is using too much salt, it can leave behind a noticeable salty taste. This is one of the most important issues to address because it can affect both taste and overall water quality.

A sulfur or rotten egg smell is usually caused by hydrogen sulfide gas. This can develop in certain water sources or plumbing systems and is more common in well water, though it can appear in municipal systems as well.

This type of taste is very noticeable and tends to get worse when water sits in pipes for a period of time.

If your water tastes fine one day and different the next, the cause is often a change in the water source or treatment process. Water providers may switch between different sources throughout the year, especially in regions that rely on a mix of imported and local water.

Seasonal changes, rainfall, and demand can all impact the mineral content and treatment levels in your water, which directly affects taste.

In most cases, water that tastes bad is still safe to drink. Municipal systems are required to meet strict safety standards, even if the taste is not ideal.

That said, taste changes can sometimes signal underlying issues such as pipe corrosion or high mineral levels. If the flavor is strong or persistent, it is worth having your water tested to better understand what is causing the problem.

The best solution depends on what is causing the taste issue. Different problems require different types of treatment.

Chlorine taste is typically improved with carbon filtration. Metallic flavors from iron or copper may require specialized filtration or a reverse osmosis system. Salty water is often best addressed with reverse osmosis as well, especially if a water softener is involved. Sulfur odors usually need oxidation or targeted filtration systems.

Because every home’s water is different, a professional water test is the most effective way to identify the exact cause and choose the right solution.

Whether or not you can taste something is not directly related to what you should worry about. Some of the most poisonous elements that could be lurking in your water are actually odorless and tasteless — including arsenic, nitrates and lead.

Though your water tastes unpleasant, it’s likely not a cause for immediate health concern. Have your water tested for free by Culligan to know what is in your water, and what you can do if you want your tap water to have a more pure, clean taste.

One indicator of malfunction with your home water supply — or even your own body — is a sudden change of taste or smell. You should know what your tap water tastes like. If one day you wake up and it tastes different, please react accordingly.

Test each faucet to see if it might be one water line or your entire home. If the taste in each faucet is similar, ask your neighbor if they notice any changes in their tap water. Even if you own a private well, your closest neighbors likely have similar external influences on their water supply.

In rare instances, a sudden change in taste can be a harbinger of a deeper health issue with how your brain receives information from your senses. This can range from simple sinus issues to strokes. Contact your physician if you feel a change in taste is a symptom of health problems.
