When it’s time to consider re-piping your home, understanding the variety of pipes available is crucial. Modern plumbing offers several materials, each with its own set of characteristics suitable for different applications.

PEX A and PEX B, for example, have become favorites due to their flexibility, allowing for fewer fittings and thus fewer potential leak points. PEX A has the added advantage of recovering from kinks due to its thermal memory, while PEX B, although slightly less flexible, still provides excellent performance. Both types require protection from UV light if used outdoors.


CPVC has emerged as a reliable choice for both hot and cold water lines, capable of handling higher temperatures than regular PVC, up to 180 degrees Fahrenheit, making it a cost-effective solution with ease of installation. It’s been treated to ensure safety for drinking water, offering peace of mind.

PVC, on the other hand, finds its strength in drain lines and vent systems where high temperatures aren’t a concern. It’s durable, lightweight, and resistant to many chemicals, making it ideal for these applications, though it uses a solvent cement for connections which must be applied carefully to prevent leaks.

Cast iron pipes are less common in new installations but are still prevalent in older structures for sewage and drainage. Known for their longevity, they can last up to a century and are excellent at muffling noise, though their weight and the labor required for installation or replacement can be significant drawbacks.

Choosing the appropriate pipe involves several considerations. Water quality can be affected by the pipe material, potentially influencing taste or introducing health concerns. The local climate plays a role, as extreme temperatures might degrade certain materials faster than others. Budget constraints need to balance initial costs with long-term durability and maintenance. Moreover, local regulations might limit or specify the types of materials you can use.


In essence, the decision on which pipes to use for re-piping is not just about picking a material; it’s about matching the best material to the needs of the house, the environment, and the homeowner’s budget. Professionals often use a mix of these materials to optimize the plumbing system’s efficiency and durability. For homeowners embarking on this significant home improvement, consulting with a plumbing professional can ensure that the choices made are tailored to their specific situation, ensuring the longevity and health of their home’s water system.
