PEX Plumbing Pipes vs Copper Plumbing Pipes

Many of our customers often ask about the various types of plumbing pipes that are available to them when looking to repipe, therefore I wanted to take some time and try to explain the differences between the two main options and the advantages and disadvantages of each. Almost all new plumbing pipes used today to replace old, rusty, and galvanized pipes are either Copper pipes or PEX pipes. Many homeowners do not know what Copper or PEX piping consists of, what each looks like, the cost of each, the benefits of each, and the drawbacks of each, until they are faced with a situation where they need to repipe a bathroom or often the whole plumbing system in their house. My goal is to provide enough information pertaining to Copper and PEX piping to ensure anyone done reading this post will have a fairly good idea of their options and can think about which one will meet their need the best. We do have specific pages on our site pertaining to PEX Piping and Copper Piping with all the details regarding each type of plumbing pipe, so if you have the time, please check those out to obtain further knowledge. I will start out by explaining a bit about PEX plumbing pipes, then move to copper plumbing pipes and end with some thoughts on the two and scenarios and reasons as to why you would pick one over the other.

PEX Plumbing Pipes

I’d like to start out by showing you a picture of what PEX piping actually looks like. You will notice that PEX piping is a very colorful and flexible material.

Besides being colorful and flexible, PEX pipes are also very durable, there is less chance of future leaks, they are quieter, resistant to extreme high and low temperatures, efficient, provide fast flowing water, can reduce your utility bills, are environmentally friendly, and last a lifetime! How could I have forgotten to mention…. Plumbing with PEX piping is also cost effective! Two reasons why Plumbing with PEX is cheaper than plumbing with copper is that the material is cheaper and it requires a lot less effort from Plumbers to implement a new plumbing system using PEX pipes. I want to share another photo of a PEX plumbing job we did recently. It was a new construction and I took a picture to share. Key things to look for: the flexibility of the PEX tubes, the joints, and how the PEX tubes are secured (secured to floor joists every 36 inches or less.)

You should now have some knowledge regarding Plumbing with PEX pipes, so I will explain a bit about Plumbing with Copper Pipes.

Copper Plumbing Pipes

Again, to start out, I’d like to show you a picture of Copper plumbing pipes. I took this picture during a recent new construction project using copper pipes. In the image you can also see the drain plumbing done with ABS pipes. Key things to look for in the image are the rigidness of the Copper Pipes, the metallic color, and the joints.

Right away, you should notice the physical differences between copper pipes and PEX pipes. Of course the physical difference is only a part of it, so I will share some of the advantages of repiping with Copper Pipes. Copper Plumbing pipes are very durable (lasting over a hundred years), are weather resistant (can be used outside of the house as well as the inside), are corrosion resistant, and will not burn in case of fire. Two important items that I want to cover separately are cost and the fact that copper plumbing pipes can be recycled. Copper pipes are more expensive than PEX pipes merely because the copper material itself is more expensive. Installing a New Copper Plumbing System is also more expensive as it’s more difficult and requires expertise and experience to ensure a solid long lasting outcome. As far as copper piping being recyclable, it is really not an advantage for two main reasons; one, once installed, you will not need to replace them for decades, possibly centuries and two, we've had various people contact us for a New PEX Plumbing System because their copper pipes were stolen and they did not want that to happen again. Thieves merely cut the copper pipes and recycle them for money. To sum it up, Plumbing with Copper Pipes is more expensive up front, but with a 50 year manufacture warranty, will last a lifetime. You should now have a general idea pertaining to Plumbing with Copper Piping and Plumbing with PEX Piping.

I've tried to share the overall advantages of the two main forms of plumbing pipes used by plumbers today in both residential and commercial plumbing work, as there is a lot of detail that I've left out. Again, if you’re interested in learning more about the two, please ensure to take a look at our PEX Piping and Copper Piping information pages.

Last but not least, I’d like to provide you with a very valuable and informative chart that I've created, showing the advantages and disadvantages of Copper Plumbing Pipes and PEX Plumbing Pipes.
