As a specialist in the field of water supply and plumbing materials, I have extensive knowledge about the types of pipes that are safe for drinking water. When it comes to polyvinyl chloride (PVC) pipes, there are a few important considerations to ensure they are suitable for use with potable water.
Firstly, it's crucial to understand that not all PVC pipes are created equal. There are different types of PVC formulations, and some are specifically designed for use with drinking water. The key is to look for PVC pipes that are labeled as "drinking water safe" or "potable water approved." These pipes have undergone rigorous testing to meet the standards set by regulatory bodies such as the National Sanitation Foundation (NSF) and the American National Standards Institute (ANSI).
One of the primary concerns with using PVC pipes for drinking water is the potential for chemical leaching. However, high-quality PVC pipes that are approved for potable water use have undergone extensive testing to ensure that they do not leach harmful chemicals into the water supply. This is particularly important for pipes that will be used in contact with hot water, as higher temperatures can increase the rate of chemical leaching.
Another factor to consider is the durability and longevity of the PVC pipes. PVC is a versatile material that is known for its resistance to corrosion and its ability to withstand a wide range of temperatures. This makes it an excellent choice for both hot and cold water applications. However, it's important to ensure that the PVC pipes are properly installed and maintained to maximize their lifespan and performance.
In addition to PVC, chlorinated polyvinyl chloride (CPVC) is another type of plastic pipe that is commonly used in plumbing systems. CPVC is similar to PVC but has been modified to include chlorine, which increases its heat resistance and makes it suitable for use with hot water systems. Like PVC, CPVC pipes that are approved for potable water use have been tested to ensure they do not leach harmful chemicals into the water supply.
It's also worth noting that older homes may have plumbing systems that include lead or other materials that can contaminate drinking water. If you live in an older home, it's a good idea to have your water tested to determine if there are any issues with lead or other contaminants. If lead is a problem, replacing the plumbing system with PVC or CPVC pipes that are approved for potable water use can help to alleviate this issue.
In conclusion, when selecting PVC pipes for use with drinking water, it's essential to choose pipes that are labeled as "drinking water safe" or "potable water approved." These pipes have been tested to ensure they do not leach harmful chemicals into the water supply and are suitable for use with both hot and cold water applications. Proper installation and maintenance are also crucial to ensure the longevity and performance of the PVC pipes. And for older homes, water testing and potentially replacing the plumbing system with approved materials can help to ensure a safe and clean water supply.

Those living in older homes should have their water tested to see if lead is a problem. Plastic pipe such as PVC (polyvinyl chloride, used for cold water only), and CPVC (chlorinated polyvinyl chloride, used for both hot and cold water) have been around for years, and both are approved for use with drinking water.read more >>
