Many older homes rely on copper plumbing or galvanized steel plumbing. However, many newer homes are looking at more efficient and cost-effective alternatives. PEX, also known as cross-linked polyethylene, is a revolutionary type of plastic material used for plumbing. Many plumbers recommend this type of plumbing for new homes because it comes with a plethora of advantages that traditional plumbing simply cannot provide.

If you’re considering repaving your entire home or if you need to replace certain sections of the plumbing, you should highly consider opting for PEX plumbing. Our plumbers can walk you through the advantages and drawbacks of this decision, and can help you come up with a design that will best suit your home. We’ve come up with this comprehensive guide to provide you with more details on what to expect.

The Three Different Types of PEX Plumbing

Not all PEX plumbing is the same. In fact, there are many different types of PEX plumbing out there. Understanding the unique features, advantages and drawbacks of each one can help you and your Chattanooga, TN plumber make a better decision on what is best suited for your home. I’ll take a look at the different types of PEX plumbing below.

Regardless of the type of plumbing that you choose, you should aim to stick with the same manufacturer if possible for all of the components. If you mix different pipes and fittings from various manufacturers, it may affect your warranty. It could also add some frustration to the installation process and make it a lot more complicated than it has to be. If you go with just one brand, you can rest assured that the warranty will not be affected.

If you’re unsure of which manufacturer to go with, speak with one of our plumbers. They’ll be able to give you some recommendations based on their own experiences. They’ll let you know whether any other homeowners have run into any problems with certain brands down the road. Our professionals can also tell you how likely the plumbing is going to break down and whether there are any other issues that you need to be aware of.

Type #1: PEX-a Pipes

Manufactured using the “Engel” method, PEX-a pipes are also referred to as hot cross linking plumbing. This is because the polyethylene molecules in the plumbing are linked during the extrusion process when the polyethylene has reached a temperature above its melting point. This method was invented by a German inventor known as Dr. Thomas Engel.

PEX-a plumbing tends to be a lot more durable than the other types of pecks plumbing available. This is because the method of construction creates the highest degree of cross-linking. It’s about 85%. The crosslinking creates a structure that is much more flexible than other alternatives. It is able to create a very tight bend.

PEX-a plumbing also offers a very unique thermal and elastic memory, which basically means that the integrity of the pipes is better as it undergoes freeze and thaw cycles. It also means that this type of plumbing is easier to repair, as you can usually fix kinks with just a heat gun. No other type of PEX plumbing offers this advantage.

Type #2: PEX-b Pipes

Next up, we have PEX-b pipes. Instead of getting crosslinked at the peak of the extrusion process, this type of plumbing is crosslinked after the extrusion process has been completed. Manufacturers will place the pipe in a steam sauna or in some type of hot water bath, which will result in a crosslinking percentage that ranges from 65 to 70. The crosslinks are not as evenly distributed as with PEX-a pipes, so PEX-b pipes tend to be a lot stiffer. They’re not as ideal for tight spaces.

This type of plumbing usually works best with insert fittings that rely on stainless steel clamp rings to hold the fitting in place. Push-to-connect fittings are not as recommended for PEX-b pipes, as they can blow off if they are placed in high-pressure situations.

A drawback of this type of plumbing is that it doesn’t have the same degree of thermal memory as PEX-a pipes. This means that you won’t be able to repair kinks with just a heat gun. You’ll likely need to cut out the damaged part of the plumbing and install a coupling instead. This means that the repair process usually takes longer and is more costly.

Another thing to note is that PEX-b pipes aren’t a great choice in situations where there will be a lot of expansion. As PEX-b pipes tend to be stiffer, high-pressure situations can easily create tiny cracks when the walls are getting expanded. This can compromise the integrity and shape of the fitting connection.

Type #3: PEX-c Pipes

PEX-c pipes are a bit different from PEX-a and PEX-b pipes because of the way that it’s made. It feels much more interesting in comparison to the two different types above. PEX-c pipes uses an electron beam to change the overall molecular structure of the plumbing after it has already gone through the extrusion process.

This electron beam isn’t as effective as creating crosslinks. Only about 70% to 75% of the material will undergo crosslinking. While this type of material has many advantages, it’s important to note that some of the side effects include discoloration from oxidation and a slightly stiffer material integrity. It does offer more crosslinking than PEX-b pipes.

This type of PEX plumbing is not as sturdy when used in joint connections and cannot be repaired with a heat gun like PEX-a plumbing. However, it is often much more affordable, and you can usually find it a great price. If you’re looking for something that will fit a certain budget, this is the type of plumbing that will often get the job done. Best of all, it’s really easy to find this material in Chattanooga, TN.
