Two of the most common types of pipes used for plumbing are PEX and copper. In some applications, they can be used interchangeably, but there are many differences between the two. Let’s take a look at some of these, and then you can decide which one will work best for you.
What is PEX? What is Copper Piping?
PEX stands for “cross-linked polyethylene” and refers to a special type of plastic pipe used for residential or commercial plumbing. Although it was invented in the 1930s, it took nearly 50 years before it was used for domestic plumbing.
Copper piping has existed for roughly 6,000 years but has only been used for plumbing purposes for about 100 years. At one point, it was used in nearly 90% of home plumbing systems.
Differences Between PEX and Copper Piping
There are several differences between the two, including origin, uses, and costs.
First, cross-linked polyethylene is derived from a natural byproduct when drilling for oil and natural gas, while copper has to be mined. Because of that increased cost of production, PEX is significantly less expensive, running less than half the price per linear square foot.
Second, traditional metal piping holds up better against sunlight. Polyethylene will deteriorate in as few as 30 days when subjected to the sun’s rays, whereas the more traditional method can last for decades.
Next, polyethylene is more flexible and therefore often easier to install. Instead of using a soldering iron to connect pieces, PEX uses connecting pieces of the same material. It can maneuver around tight spaces much more easily than the hardened metal of its predecessor.
However, polyethylene also has a shorter expected lifespan, usually only lasting between 25 and 40 years. Copper, on the other hand, can easily last 50 years or more. PEX is also more susceptible to damage from chemicals or solvents, although the alternative also requires regular maintenance to prevent buildup, rust, and corrosion.
Finally, metal pipes can withstand higher temperatures than their plastic-based counterparts. Polyethylene doesn’t “melt,” strictly speaking, but the structural integrity of the pipe can still be compromised over time.
Which is Better?
As both copper and cross-linked polyethylene pipes have different strengths and weaknesses, the best fit for you will depend on your specific situation. Let’s look at the benefits that each one provides over the alternative, and then you can decide which one is right for you.
Modern PEX pipes work best when:
- Water temperature is more moderate
- Cost is a factor
- The path of the pipe is not a straight line and requires bends or curves
- Chemicals or solvents aren’t used frequently
- It’s a DIY operation and you’d rather avoid using a soldering iron
- All pipes are underground or otherwise outside of the path of direct sunlight
- Lower levels of maintenance are desired
- You’d prefer a modern look
On the other hand, traditional copper pipes are preferred if:
- Large amounts of hot water will be flowing through the pipes regularly
- Any part of the piping system will be outside or in direct sunlight
- Chemicals, solvents, or cleaners are frequently used
- Price is not an object
- The pipes will be installed in a linear fashion with little or no curvature needed
- You’re willing to put in a little extra time for proper upkeep
- The pipes will be installed by professionals who can handle the soldering
- You’d like a more traditional look for your pipes
Additional Notes and Final Thoughts
For a home’s resale value, the material used for pipes may not matter to most buyers, but among those who have a preference, some may rather have the modern polyethylene variety, while others may prefer the traditional metal. The style and age of your home may play a role in this as well, as potential buyers looking at modern homes may not prefer traditional plumbing materials and vice versa.
If you still aren’t sure which option is better for your home, it’s always a good idea to check with the experts. They can perform a comprehensive assessment of the area where the pipe will be installed, tell you which type will work best for your situation (or if one type won’t work at all), and give you an estimate on how much each one will cost.
