PEX Plumbing: Understanding the Health Risks and Disadvantages

PEX plumbing has become increasingly popular in recent years as a cheaper and more flexible alternative to traditional copper piping. PEX, which stands for cross-linked polyethylene, is a type of plastic tubing that is used for water supply systems in homes and businesses. While PEX may seem like a convenient choice, it does come with some health risks and disadvantages that homeowners should be aware of.

Health Risks of PEX Plumbing

One of the biggest concerns with PEX plumbing is the potential health risks associated with the chemicals used in its manufacture. PEX tubing is often treated with chemicals such as benzene and toluene, which are known carcinogens. These chemicals can leach into the water supply, especially if the water is left sitting in the pipes for long periods. Additionally, PEX has been known to harbor bacteria, which can pose a risk to human health.

Disadvantages of PEX Plumbing

Aside from the health risks, there are several disadvantages to using PEX plumbing. PEX is more susceptible to damage from UV exposure, which means it must be stored, handled, and installed carefully to avoid exposure to sunlight. PEX is also prone to kinking, which can restrict water flow and cause pressure issues. Additionally, some fittings have been recalled due to failure which has caused significant water damage to many homes.

Why Copper is the Preferred Plumbing Pipe

Copper piping has been the standard in plumbing for decades, and for good reason. Copper is a safe, reliable, and durable material that is resistant to bacteria and other harmful substances. Unlike PEX, copper is not treated with any harmful chemicals during its manufacture, and it does not pose a risk to human health. Additionally, copper piping is easy to install and maintain, and it can last for many years with proper care.

Copper piping is also less susceptible to damage from UV exposure and kinking, making it a more reliable choice for homeowners. Copper is also a good conductor of heat, which means it can help to regulate water temperature and reduce energy costs. Finally, copper piping is an eco-friendly choice, as it is a recyclable material that can be reused again and again.

While PEX plumbing may seem like a convenient and affordable option, it comes with significant health risks and disadvantages. Copper piping is the preferred plumbing pipe for its health benefits, reliability, safety, and other advantages. If you are considering installing new plumbing in your home or business, choose copper for a safe and durable solution that will provide you with years of worry-free service.
