Choosing the correct type of plumbing pipe will greatly influence home plumbing systems’ efficiency, cost-effectiveness, and longevity. One of the standout choices for many homeowners today is PEX piping, known formally as cross-linked polyethylene piping. In this article, we will explore the various benefits of PEX piping to help homeowners understand why it’s often the preferred material for a wide range of plumbing applications.

What is PEX Piping?

PEX piping is flexible plastic piping that has gained popularity over the last twenty years. Made from polyethylene, PEX pipes undergo a process known as cross-linking, which creates bonds between the polyethylene molecules, producing a more durable plastic. This cross-linking enhances the physical properties of the pipes, making them able to withstand extreme temperatures and resistant to chemical influences.

Benefits of Using PEX Piping

PEX pipe is used in many applications, such as radiant floor heating, potable and non-potable water transport, and recirculating hot water systems. It is also durable enough for outdoor plumbing. Here are other reasons to use PEX pipe.


PEX is highly flexible, which allows it to be installed with fewer fittings than rigid plumbing systems. This flexibility not only makes it easier to install but also significantly reduces the risk of leaks that can occur at joint points. The ability to bend PEX piping around corners also minimizes the need for elbow fittings and other connectors, which are potential weak points in a plumbing system.


PEX is incredibly durable and resistant to stress-related fractures. Unlike copper or PVC piping, PEX does not corrode or develop pinhole leaks. It is also resistant to scale and chlorine, which can degrade other types of piping over time. Moreover, PEX can expand, making it more resistant to damage from frozen water in the pipes, which is a common issue in homes with colder weather. 


PEX piping tends to be less expensive than other materials like copper, mainly due to its ease of installation and, therefore, lower labor costs. Its flexibility reduces costs because it can be installed more quickly and requires fewer connections and fittings. Additionally, the material cost of PEX is relatively low, making it a cost-effective choice for both new installations and repairs.

Energy Efficiency

PEX piping has better insulating properties than materials like copper. This means that hot water delivered through PEX pipes loses less heat as it moves from the water heater to the faucet. This, along with the reduced strain on the water heater, significantly increases its energy effectiveness.

Safety Concerns Reduced

PEX does not corrode, which can improve the safety of the water that travels through it. Corroded pipes can leach metals like lead and copper into drinking water, posing health risks. PEX’s resistance to scale and chlorine also means that the internal surface of the pipes remains smooth over time, ensuring that water quality is not jeopardized.


PEX piping can be used in various applications, including hot and cold water supply systems, radiant heating systems, and snow-melting applications. Its resistance to high temperatures and pressures makes it suitable for diverse plumbing needs in residential and commercial buildings. It also can be combined with other types of pipe materials that may already exist inside a home. 


PEX piping is designed to last. Under optimal conditions, its lifespan can exceed 50 years, and many manufacturers offer warranties that reflect its durability. This longevity can provide homeowners with peace of mind, knowing that their plumbing system will remain reliable for many years to come.

Ease of Repair

PEX piping is much easier to repair than other materials in the event of damage or when modifications are required. Because it is flexible and available in long lengths with varying diameters, it can often be easily repaired with simple tools and minimal new fittings. The type of fitting used will depend on the type used, but all are simple, thus saving time and reducing the complexity of maintenance work.
