PEX or copper for a residential repipe

Updated: Sep 8, 2023

When it comes to repiping your home, choosing the right material is a crucial decision that can impact the longevity and performance of your plumbing system. Two popular options that homeowners often consider are cross-linked polyethylene (PEX) and copper. In this blog post, we will explore the pros and cons of each material to help you make an informed choice for your residential repipe project.

PEX for Residential Repipes:

PEX has gained significant popularity in recent years due to its numerous benefits and versatility. Here are some key advantages of using PEX for your residential repipe:

  1. Cost-effective: PEX piping is generally more cost-effective than copper, making it an attractive option for budget-conscious homeowners. The material itself is less expensive, and its installation requires fewer fittings and connections, reducing labor costs.

  2. Excellent flexibility: PEX pipes are highly flexible, allowing for easy installation around corners, through tight spaces, and within existing structures. This flexibility makes PEX an ideal choice for retrofitting and minimizing the need for extensive wall modifications.

  3. Resistant to corrosion: Unlike copper, PEX is not prone to corrosion or scale buildup. This resistance ensures a longer lifespan for your plumbing system and reduces the risk of leaks and potential water damage.

  4. Freeze resistance: PEX pipes have the ability to expand and contract with freezing temperatures, reducing the likelihood of bursting. This feature is especially advantageous in colder climates.

  5. Quiet operation: PEX pipes are known for their quiet operation as they minimize water hammer noises commonly associated with copper plumbing systems.

Copper for Residential Repipes:

Copper pipes have been a longstanding choice for residential plumbing, and they come with their own set of advantages. Here are some reasons why copper may be a suitable option for your residential repipe:

  1. Durability and longevity: Copper pipes are known for their durability and long lifespan. With proper installation and maintenance, copper plumbing systems can last for several decades, making them a reliable choice.

  2. Heat resistance: Copper has excellent heat resistance properties, making it suitable for both hot and cold water applications. It can withstand high temperatures without warping or compromising its structural integrity.

  3. Proven track record: Copper has been widely used in plumbing for many years, and its performance and reliability have stood the test of time. It is a trusted material with a proven track record in residential plumbing systems.

  4. Recyclability: Copper is a highly recyclable material, making it an environmentally friendly choice for those who prioritize sustainability.

Choosing the Right Option:

Selecting the appropriate material for your residential repipe ultimately depends on various factors, including your budget, preferences, and specific requirements. While PEX offers cost-effectiveness, flexibility, and corrosion resistance, copper boasts durability, proven performance, and recyclability.
