Copper vs. PEX: Whole House Repipe

Copper or PEX: Whole House Repipe

When it comes time for updating your pipes, there are two materials available for replacing the old pipes: copper pipe or PEX tubing. Copper is the old method that has stood the test of time, and is the favorite of many plumbers. PEX is the new material on the scene. While everything in construction has a lifespan, both of these materials have proven themselves valuable in the plumbing industry.

Copper Pipe

Is a long-lasting material, and has a proven history. It comes in pipe lengths of up to 10' and assembles by cutting it to length and soldering fittings between lengths of pipe. However, for replacing the pipes in a house, you do have to deal with the fact it is rigid. In order to replace all of the pipes with copper, we will have to open a lot of the walls that contain the plumbing. If you are doing a major remodel or have extensive leak damage, the walls are open anyway.

PEX Tubing

PEX is cross-linked polyethylene tubing, and is the new product on the market. While it has been around for about half a century, it has not been commonly used for quite that long. It is showing signs of lasting well and has advantages that recommend it. While copper pipe comes in 10' lengths, PEX comes in coils that are several hundred feet. It is also flexible and is not limited to straight runs, both of these features mean that there are less fittings involved in running PEX. Since your fittings are often your weakest point, less is better. PEX is prone to damage by sunlight, making it a poor choice for any exposed piping especially outdoors.
