Understanding PEX Pipes
What is pex pipe? PEX pipe, which stands for Cross-Linked Polyethylene pipe, is a type of plastic piping used in a variety of residential and commercial plumbing applications. Introduced in the 1960s, PEX tube has increased in popularity due to its flexibility, durability, and cost-effectiveness. And now pex tubing is widely use in plubming and underfloor heating piping system.
How many types of pex pipes we have? We have pex a pipe, pex b pipe, and pex c pipe. For the details, you can visit this article What’s the difference between Between PEX A, PEX B, and PEX C Pipes?

Importance of understanding the possible pex pipe problems
PEX piping, like any other material, has a few common issues that you may experience over the course of time. Although they are generally durable and robust, understanding common problems associated with PEX pipes can help you prevent, identify, and resolve any issues that might arise.
Here are some common pex pipe problems and why it's crucial to understand them:
Commen problems for pex pipes
Degradation In Sunlight
PEX pipes can degrade if they're regularly exposed to sunlight. This can compromise the pipe's integrity and lifespan. Anyone planning to use PEX should be aware of this to ensure the pipes are properly stored before installation and adequately protected once installed.
Preventive measures
PEX pipes, while boasting many benefits, are known to be susceptible to damage when exposed to ultraviolet (UV) light, particularly from the sun. UV rays can cause the material to become brittle and crack, reducing the lifespan of the pipes. Below are several preventive measures you can take to protect your PEX pipes from UV exposure.
Indoor Storage: If your PEX pipes are not yet installed, it's important to store them indoors away from direct sunlight or in an area that does not receive any UV rays.
Using UV Resistant Coverings: When PEX pipes have to be installed in areas exposed to sun, use UV-resistant coverings or sleeves for the pipes. This can be a specially designed tape, pipe insulation or conduit.
UV Resistant PEX: Certain brands produce UV-resistant PEX pipes; they might cost more but are worth considering if exposure to sunlight is unavoidable.
Encasing or Burying: If it’s possible, encase or bury exposed PEX pipes underground or within walls or concrete wherever applicable. This is a great way to completely avoid direct sunlight exposure.
Chemical Exposure
Certain chemicals can have a damaging effect on PEX pipes. This includes some types of water treatments or the transport of particular chemicals. Knowing about potential chemical degradation can help ensure that the water flowing through your pipes is not contributing to their wear and tear.
Incompatibility with Some Fittings
While PEX pipes are versatile, they aren't compatible with all types of fittings. In particular, PEX can react negatively when contact occurs with certain types of metal. PEX-specific fittings should be used to avoid any problems with incompatibility.
Improper Installation
Often, problems with PEX stem from improper installation rather than a problem with the pipes themselves. Incorrect fittings, wrongly sized pipes, or flawed crimping can lead to leaks or pipe damage.

We must use the correct tools and cut the pipe right. How to cut the pex pipe? Cutting PEX pipe is a simple task, but it's important to do it correctly to prevent any leaks or damage. Here's a step-by-step guide on how to achieve a clean and precise cut every time.
Tools You'll Need:
PEX Pipe Cutter: These are specifically designed to cut PEX piping, and they ensure a clean, straight cut.
Steps:
Measure and Mark: Determine the length of PEX pipe you need for your project. Measure and mark the spot where you want to cut with a permanent marker.
Position the Cutter: Open your PEX pipe cutter and insert the pipe between its blades, aligning the cutting edge with the mark you made on the pipe.
Make the Cut: Once the pipe is properly positioned, apply pressure to the cutter to initiate the slice. Ensure the cut is perpendicularly straight to avoid any possible leaks. Apply steady pressure; you shouldn't need to force it.
Inspect the Cut: After cutting the pipe, inspect the end to make sure the cut is clean and straight. There should not be any burrs or crimped spots on the pipe.
Conclusion
Understanding these potential problems benefits you by helping to prevent issues before they happen. Regular inspection and maintenance of your PEX system can ensure you detect and handle any issues promptly, extending the life and performance of your plumbing and heating system. How long does pex pipe last? If we can know well the pex pipe problems and prevent the issues before they happen, the lifespan for pex pipe can be 50 years.
