There are several reasons why water may taste like plastic. One common cause is the use of plastic containers or bottles, especially if the water has been sitting in the container for a prolonged period. Plastic water bottles, especially polycarbonate bottles, can release BPA and other chemicals into the water, imparting a plastic taste. Additionally, the type of plumbing pipes used can also affect the taste and smell of water. New plastic pipes or faucets may temporarily impart a plastic flavour, which usually fades with time and increased water usage. In some cases, the presence of toxins or impurities in the plumbing system or water source can result in a plastic taste. It is important to identify the cause and take appropriate measures, such as using alternative containers, installing water filtration systems, or seeking professional help to address plumbing or water quality issues.

What You'll Learn
Plastic plumbing
There are several types of plastic plumbing pipes available, each with its own advantages and disadvantages. Polyvinyl chloride (PVC) pipes are among the most common. They are affordable, durable, recyclable, and can stay in good condition for up to 70 years. PVC pipes do not contain bisphenol A (BPA), which is known to have estrogen-like effects on mice at certain levels. However, PVC is known to contain phthalates, which can leach into the water and give it a plastic taste or odour.
Cross-linked polyethylene (PEX) pipes are a newer type of plastic plumbing pipe. They are more flexible than PVC, making them quicker and easier to install. PEX pipes are also naturally heat-resistant and less likely to burst during freezing temperatures. However, their potential lifespan has not yet been determined.
Another option is acrylonitrile butadiene styrene (ABS) pipes, which are extremely strong and resistant to extreme weather conditions, including UV light exposure and cold temperatures. ABS pipes are often used in outdoor plumbing applications and are quicker to install than PVC pipes.
While plastic plumbing pipes offer many advantages, it is important to consider the potential impact on water taste and odour, as well as any health risks associated with certain chemicals leaching into the water.

Plastic water bottles
To avoid the plastic taste, it is recommended to switch to glass, stainless steel, or polyethylene terephthalate (PETE) bottles, as these materials do not absorb or retain flavours. Reusable bottles are also preferable to disposable ones, as they reduce plastic waste and offer a variety of materials and designs.
If you prefer to use plastic water bottles, there are a few ways to minimize the plastic taste:
- Ensure the bottle is thoroughly cleaned and dried between uses. Proper cleaning and drying prevent the buildup of residue and odours, as well as reduce the risk of bacterial growth.
- Avoid exposing the bottle to heat and sunlight, as this can alter the taste and quality of the water.
- Try treating new bottles with a diluted vinegar mixture, then washing them thoroughly. This can help remove any initial odours or flavours.
- Consider using a bottle with a built-in filter or purifier, which can help remove impurities, chemicals, and odours, improving the taste of the water.
By following these suggestions, you can minimize the plastic taste in your water bottles and ensure a cleaner and more enjoyable drinking experience.

Health implications
Water is an essential part of our daily lives, and its quality is crucial for our health. While most people prefer water to have a neutral, pleasant taste or no taste at all, some individuals may notice a plastic flavour in their water supply. This unusual taste can be concerning and may have several health implications.
Firstly, the plastic taste in water could indicate the presence of contaminants. Plastic pipes have been known to affect the taste and smell of water. This is particularly true for new plastic piping, which can impart a plastic flavour or odour to the water. Different types of plastic are more prone to this issue, with research indicating that HDPE, PEX-a, and PEX-b are more likely to cause a plastic taste, while cpVC is less likely to do so. Additionally, the use of strong solvents during plumbing work can leave an undesirable taste and odour in the water.
Secondly, the plastic taste in water could be due to the leaching of chemicals from plastic containers or plumbing. This is especially true if water is stored or comes into contact with plastic for an extended period. Phthalates, UV stabilizers, lubricants, and other additives used in plastic manufacturing can contaminate the water, and these chemicals may have potential health effects. For example, polycarbonate water bottles (hard plastic bottles) can release BPA, which has been shown to have estrogen-like effects on mice at levels similar to or lower than those experienced by humans. However, long-term human studies on BPA exposure are lacking.
Thirdly, the presence of a plastic taste in water could be a sign of a larger issue with the water supply or plumbing system. Extreme or sudden changes in water taste or odour can indicate the buildup of toxins or contaminants, which can have serious health implications. Issues with piping, such as deteriorated pipes, lack of check valves, or improper connections, can lead to water contamination. In such cases, individuals may be consuming water that has come into contact with contaminated water from other sources or appliances.
Lastly, while rare, a persistent plastic taste in water could be indicative of an underlying medical condition. However, this is less likely to be the cause and should be considered after investigating external factors.
Overall, the health implications of tasting plastic in water can vary. While most causes are harmless, it is essential to determine the reason for the plastic taste and address it. This may involve seeking professional help, installing water filtration systems, or switching to alternative plumbing materials or water containers.

Removing the plastic taste
Water stored in plastic containers can often taste like plastic. This is because water absorbs flavours from any porous container it is stored in. The plastic taste could be due to the leaching of chemicals from the plastic into the water. Polycarbonate water bottles, for instance, can release BPA into the water. Other chemicals that may be leached include plasticizers, UV stabilizers, lubricants, pyrolozates, and phthalates.
If you are experiencing a plastic taste in your water, you should try to identify the cause and work to purify your water of the contaminants causing the taste. You can try switching to glass or stainless steel containers to see if the flavour improves.
If you are using plastic containers, you can try cleaning them with soap and water, and ensuring that they are dry before reuse. You can also try using diluted vinegar, baking soda, or denture tablets to clean the containers and remove the plastic taste.
If you are getting a plastic taste from your tap water, it could be due to the use of plastic pipes or recent plumbing work. You can try seeking professional help to address the problem or switch to a filtration system to purify your water.

Other causes of unusual tastes
Water can sometimes taste or smell unusual due to a variety of reasons. One common reason is the use of plastic containers or bottles, especially if the water has been sitting in the container for a while. Plastic water bottles, especially hard plastic bottles, can release BPA and other chemicals into the water. Additionally, plastic pipes used in plumbing can also affect the taste and smell of water, with some people noticing a plastic taste or smell in their tap water. This can be due to the use of strong solvents or sealing products during plumbing work, or the presence of chlorine in city water.
Another factor that can influence the taste of water is the type of plumbing pipes used. While copper pipes were commonly used in the past, some buildings now use galvanized plumbing, which can impart a metallic flavour from the zinc and manganese. Although this is not harmful to health, it can be unappealing to some.
The source of water can also affect its taste and odour. Switching from city water to well water, for example, can result in noticeable differences due to variations in mineral content and chlorine levels. Additionally, water can absorb flavours from porous containers, so using glass or stainless steel bottles or containers may improve the taste.
It's important to note that extreme changes in the taste or odour of drinking water can be a cause for concern. Building up toxins in the plumbing system can lead to serious health issues, and switching to a filtration system can bring about health improvements. If you are experiencing persistent health problems or are concerned about the quality of your water, it is recommended to seek professional help to address the issue.
