Should I Repipe My Home with PEX or Copper?

When it comes to repiping your home, you have two main options: PEX and copper. Both have their advantages and disadvantages, but which one is right for you? DurabilityPEX tubing is more durable than copper tubing. It is immune to corrosion and mineral accumulation, and is not affected by electrolysis, which can cause small pinhole leaks in copper pipes. Copper pipes can last anywhere from six months to the life of a building, while PEX pipes can expand eight times their size before freezing.

CostPEX tends to be 30 to 40 percent less expensive than copper tubing. It also requires fewer accessories and less labor to install. Because it weighs less than copper, it also costs less to transport. All of this saves plumbers time and saves homeowners money.

These cost savings have become even more significant in recent years as copper prices have risen. For projects with a limited budget, these savings can be a decisive factor.


When it comes to repiping your home, both PEX and copper have their advantages and disadvantages. PEX is more durable and cost-effective than copper, but copper may be the better option for certain projects.

Ultimately, the decision should be based on your budget, the type of project you are undertaking, and the longevity you are looking for.
