What You'll Learn
PEX is a durable, flexible, and inexpensive alternative to copper
PEX (cross-linked polyethylene) is a type of flexible synthetic piping that has gained popularity as an alternative to copper pipes. It is made of cross-linked polyethylene, a form of flexible plastic tubing with cross-linked molecules that create great durability and strength. PEX is more freeze-resistant than other types of rigid plumbing pipes, such as copper. It is also resistant to corrosion and scale buildup, which helps extend its lifespan and prevents leaks.
PEX is generally considered to be a more cost-effective option than copper. The cost of PEX tubing depends on the diameter of the tubing needed, but it is still usually cheaper than copper. The ease of installation also makes PEX a more economical choice, as it requires less labour time and can often be installed as a DIY project.
PEX is also more flexible than copper, allowing it to bend around corners and obstacles. This reduces the number of fittings required and makes it easier to install in existing homes, as it can be snaked through walls without removing sections of drywall.
However, it's important to note that PEX has a shorter lifespan than copper. Properly maintained copper pipes can last 50 to 70 years, while PEX pipes typically last for 25 to 50 years. Copper is also considered more durable and reliable over the long term, making it a popular choice for those seeking a long-lasting plumbing solution.
In summary, PEX is a durable, flexible, and inexpensive alternative to copper pipes. It is easy to install, resistant to freezing and corrosion, and requires less maintenance. However, it has a shorter lifespan than copper and may not be suitable for those seeking a long-lasting plumbing solution.

Plastic piping is not an electrical conductor
Copper pipes have been traditionally used in plumbing, but replacing them with plastic pipes is becoming more common. Plastic pipes, such as PEX (made of cross-linked polyethylene), offer some advantages over copper. They are more flexible, easier to install, and provide better insulation. However, one important consideration when contemplating this replacement is that plastic piping is not an electrical conductor.
In older homes with electrical systems protected by fuses instead of circuit breakers, the electrical system may be grounded through metal water pipes. Replacing these metal pipes with plastic ones can interrupt this continuous grounding path, as plastic is not a conductor of electricity. This is an important safety concern that must be addressed when considering such a replacement.
The conductivity of a substance is determined by the number of electrons in the outer shell of its atoms. Metals, such as copper, have a high number of free electrons, allowing them to effectively conduct electricity. On the other hand, plastics are typically composed of long chains of carbon and hydrogen atoms, resulting in few or no free electrons. This lack of free electrons hinders the conduction of electricity through plastic materials.
While it was once widely believed that plastics were completely non-conductive, recent discoveries have challenged this notion. In 2000, Alan MacDiarmid, along with his colleagues Hideki Shirakawa and Alan J. Heeger, were awarded the Nobel Prize in Chemistry for their discovery that plastics can conduct electricity under certain circumstances. They found that by adding iodine, a strong oxidant, to the polymer, the conductivity of the plastic could be increased. Specifically, polyacetylene, a plastic used for electrical insulation, gained notoriety as the first plastic known to conduct electricity.
In conclusion, while plastic piping offers certain advantages over copper pipes, it is crucial to recognize that it is not an electrical conductor. This can have significant implications for the grounding of electrical systems in older homes. Therefore, when considering replacing metal pipes with plastic, it is highly advisable to consult with a professional to ensure that your electrical system remains properly grounded.

Plastic piping is quieter than copper
Plastic piping is a popular alternative to copper piping, offering several advantages that have made it the go-to material for many plumbers. One of the most notable benefits of plastic piping is its quietness compared to copper. Copper pipes are far noisier, especially when used with high-pressure water systems. The sound of water travelling through copper pipes can be quite loud and carry throughout the house. Plastic pipes, on the other hand, significantly reduce this noise, creating a quieter environment.
The quietness of plastic pipes is due in part to their flexibility and durability. Plastic pipes, such as PEX (cross-linked polyethylene), are flexible and durable, making them less prone to cracking and bursting. They can also withstand higher water pressure than copper pipes, reducing the risk of leaks and ruptures. PEX pipes are more freeze-resistant than copper pipes, which can burst when the temperature drops below 20 degrees Fahrenheit.
In addition to being quieter, plastic pipes are also quicker and easier to install than copper. Plastic pipes can be assembled without the need for soldering or special tools, making them a popular choice for DIY enthusiasts and professional plumbers alike. The flexibility of plastic pipes also makes it easier to route them during installation, as they can bend and fit into tighter spaces.
However, it is important to note that plastic pipes have some limitations. For example, certain types of plastic pipes, such as PVC, are not suitable for hot water applications as they can warp at high temperatures. Additionally, plastic pipes may not be allowed for use with certain appliances, such as boilers, which often require a minimum of one metre of copper piping.
When deciding whether to replace copper pipes with plastic, it is generally recommended to consult a professional plumber. While plastic pipes offer several advantages, including reduced noise, durability, and ease of installation, there are also situations where copper pipes may be the better choice. The decision should be based on factors such as climate, budget, and specific building and regional considerations.

Copper pipes can be hard to access and replace
Copper pipes are renowned for their longevity, with a lifespan of 50 years or more. However, they are not immune to degradation and corrosion, and leaks can be challenging to identify. While copper pipes are durable, accessing and replacing them can be difficult due to their rigid nature and the complexity of plumbing systems.
Replacing copper pipes often involves extensive work, as it requires disconnecting and bypassing the existing copper network. This process can be cumbersome and time-consuming, especially in older homes where pipes may be embedded in walls or located in confined spaces. In such cases, cutting into walls or floors may be necessary to access and replace the pipes, resulting in additional repair work.
The rigidity of copper pipes can also pose challenges when navigating tight spaces or making connections. Unlike flexible plastic pipes, copper pipes require precise measurements and fittings, making installation and replacement more intricate. Moreover, the joints and connections in copper piping are more susceptible to leaks, especially as the pipes age or undergo stress from water pressure or temperature fluctuations.
When dealing with copper pipes in hard-to-reach areas, such as behind appliances or in cramped spaces, replacement can be particularly cumbersome. In some cases, specialised tools may be required to access and manipulate the pipes, adding complexity and cost to the replacement process. Additionally, the replacement of copper pipes in these confined areas may necessitate the involvement of professional plumbers, further increasing the overall expense.
While copper pipes have been the standard for plumbing for many decades, modern alternatives like PEX (cross-linked polyethylene) tubing offer advantages in terms of flexibility and ease of installation. PEX pipes are less expensive, faster to install, more freeze-resistant, and less prone to leaks. They are also easier to work with in confined spaces due to their flexibility and push-fit connectors, making them a more accessible option for DIY projects or retrofitting in existing homes.
