How do you tell if you have PEX A or PEX B?
Again, the main distinction lies in the manufacturing method, which is what assigns an A, B or C to PEX. PEX A is made using the Peroxide, or Engel, method. PEX B is formed using Silane, or Moisture Cure, method. This is the most common PEX pipe type out there.
Where should you not use PEX?
PEX can't be installed in high heat areas. You can't install PEX in high heat areas like near recessed lighting. This also means you can't connect PEX directly to a hot water heater, but you can use a connecting material to do this.

It is important to note that this tubing will use 1 inch PEX fittings such as, Barbed or Compression connection fittings.
Should you insulate PEX?
You should insulate PEX pipes because they can freeze and potentially burst when temperatures drop below 20 degrees Fahrenheit. This is particularly important in cold regions, crawl spaces, attics, or other cold places. Doing so can also improve energy efficiency and reduce moisture and condensation.
How long do PEX pipes last?
50 yearsPEX: Due to its flexibility and durability, PEX piping should last at least 50 years. PVC / CPVC: Under typical conditions, these pipes should last up to 100 years. Keep in mind that PVC pipes are often used for drainage because extreme heat can damage them.

How do you tell if you have PEX A or PEX B?
Again, the main distinction lies in the manufacturing method, which is what assigns an A, B or C to PEX. PEX A is made using the Peroxide, or Engel, method. PEX B is formed using Silane, or Moisture Cure, method. This is the most common PEX pipe type out there.
How do I know if I have PEX A vs PEX B?
Flexibility - PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX-B pipe. Kink-Resistance - PEX-A has the greatest resistance, PEX-B the lowest.

What is PEX piping?
PEX pipe or PEX tubing is made of a cross-linked polyethylene plastic, which is a flexible plastic. Because of the versatility of PEX piping, and the fact that it’s flexible and cheap, it’s used for plumbing in both residential and commercial buildings. There are three types of PEX piping: A, B, and C. PEX piping comes in four colors: red, blue, white, and gray. Red is traditionally used for hot water. Blue for cold water. White and gray can be used for both hot and cold water.
When was PEX piping invented?
In 1968 , German scientist Thomas Engel discovered the process of creating the plastic for PEX piping, cross-linked polyethylene. PEX piping caught on quickly in Europe in the 1980s. In the US, however, PEX did not catch on as quickly because PEX did not initially meet US standards for drinking water. It was mostly used at first in the US only for radiant floor heating systems. Once PEX manufacturers made the plastic less susceptible to corrosion from chlorine in drinking water, PEX piping became much more prevalent in the US.
What are the disadvantages of PEX piping?
There are a couple of disadvantages to keep in mind before committing to PEX pipes on your project.
What is a push fit PEX pipe?
Push-fit connections: Push-fit connections are the quickest way to connect PEX piping. You simply purchase special fittings that grab the end of the pipe when it’s inserted, similar to a paper finger tube trap. A special removal ring is required to help you remove the pipe once it’s been connected.
What is type C PEX?
Type C PEX piping is the stiffest of the three and is more prone to kinking and cracking than the other two. It’s often used for short repairs that don’t require any bends. Type C PEX is also usually cheaper than the other two types of PEX piping.
What is the most flexible type of piping?
Type A PEX piping is the most flexible type of PEX piping, making it adaptable for all home water needs, including potable water piping. Type A PEX piping expands most out of the three types, so is most resistant to freezing and cracking, which is important in cold weather climates. While type A PEX is more expensive than the other two types of PEX piping , it is cheaper than copper pipes.
What is copper crimping?
Copper crimping: Copper crimping is one of the most common ways to connect PEX piping. In this method, a copper crimping ring slips over the end of a PEX tube and a fitting is inserted inside. A special crimping tool is used to crimp the copper ring on the outside and keep the tube inside in place.
What is PEX pipe?
Cross-linked polyethylene (PEX) pipes are flexible tubes that can be used for long runs throughout the house. They are a great alternative to traditional pipe materials like copper and galvanized steel for water lines as they do not need any joints or elbows to bend. It makes them a highly desirable option for residential properties.
Why do we put PEX pipes underground?
By installing the PEX pipes underground, we can reduce the exposure and increase the life expectancy of the pipes. PEX has the ability to expand when exposed to low temperatures, so even if the underground temperature is freezing, the outdoor PEX tubing won’t crack.
What Causes PEX to Degrade Under UV Radiation?
Outdoor PEX pipes can degrade under UV light because they absorb the chlorine-blocking antioxidants that protect the pipe.

We will discuss this in a later section.
How many types of PEX pipes are there?
Other than the color-coded property, PEX pipes have three different types. You can distinguish between them based on their manufacturing process, which determines the PEX pipe installation procedure for later use. Labeling is simple for PEX when they are stored as rolls in a hardware store. You will notice the A, B, and C labels on different pipe rolls. Therefore, select the right tubing based on your needs.
Why is PEX C so hard to use?
PEX-C is very difficult to use because it’s the stiffest of all the PEX pipe options. This type is manufactured using the irradiation method in which crosslinking is done separately from extrusion. PEX-C pipes can easily crack under low water temperatures, especially when the water freezes. They aren’t suitable for handling harsh weather conditions.
