  • Resistant to Freeze Damage: PEX pipes can expand and contract. It makes them more resistant to damage caused by freezing and thawing.
  • Lower Noise Transmission: They have the advantage of reducing water hammer noise due to their inherent flexibility. PEX’s flexibility helps dampen this effect.
  • Reduced Health Risks: PEX pipes are non-toxic and do not leach harmful chemicals into the water supply.
  • Less Prone to Corrosion: Unlike metal pipes, PEX pipes are not susceptible to corrosion, which can lead to pipe degradation and water contamination over time.
  • Energy Efficiency: They have lower heat conductivity than metal pipes, meaning they lose less heat when hot water flows through them. This energy efficiency can lead to cost savings in heating water.
  • Easy Maintenance and Repairs: Compared to rigid pipes, PEX pipes are generally easier to maintain and repair. If necessary, sections of PEX pipe can be replaced without having to replace an entire line.
  • Versatility: PEX pipes come in different colors (red, blue, and white) to signify their intended use, such as hot water, cold water, or specific applications. This color coding makes it easier for plumbers and homeowners to identify the purpose of each pipe.

Benefits of a PEX pipe:

  1. Flexible and Versatile: PEX pipes are highly flexible, allowing easy installation around obstacles and corners. Their versatility makes them suitable for various applications, including potable water systems, radiant floor heating, and hydronic heating.
  2. Corrosion Resistance: PEX pipes are made of cross-linked polyethylene, which provides excellent resistance to corrosion. This means they are less likely to develop rust or scale over time, leading to a longer lifespan than traditional metal pipes.
  3. Reduced Leak Potential: The seamless construction of PEX pipes reduces the fittings and joints required during installation. Fewer connections mean fewer potential points of failure, reducing the risk of leaks and water damage.
  4. Freeze Resistance: PEX pipes can expand slightly, making them less prone to bursting in freezing temperatures. This feature can be particularly beneficial in regions with harsh winters, as it helps prevent costly pipe replacements due to freeze damage.
  5. Energy Efficiency: PEX pipes have a smoother interior surface compared to some other materials, resulting in better water flow and reduced pressure drop. This characteristic contributes to improved energy efficiency and lower utility bills.
  6. Quieter Operation: PEX pipes have natural sound-dampening properties, which help minimize water hammer noises and vibrations often associated with metal pipes. This makes them an excellent choice for buildings where noise reduction is essential.
  7. Chemical Resistance: PEX pipes are highly resistant to chemical degradation, making them suitable for various water treatment methods and ensuring the water’s quality remains unaffected.
  8. Lightweight: PEX pipes are lighter than traditional metal pipes, making them easier to handle during installation. Their lighter weight can also lead to cost savings in transportation and labor.
  9. Longevity: When properly installed and maintained, PEX pipes have a long service life, potentially exceeding some traditional plumbing materials. This longevity contributes to reduced maintenance costs over time.

What problems can occur with a PEX pipe?

  • PEX pipe is susceptible to damage from direct exposure to sunlight or UV rays, leading to premature degradation and potential leaks.

  • Insert the PEX fitting ( an elbow, tee, or coupling) into the end of the pipe. Make sure the fitting is fully inserted correctly.
  • Position the crimp ring over the fitting’s barbed end and ensure it is about 1/8″ to 1/4″ away from the edge.
  • Use a crimping tool designed for PEX connections to compress the crimp ring. The tool applies pressure evenly around the ring, creating a tight and reliable seal.
  • Double-check the connection to ensure it is secure and leak-free. A properly crimped connection will have a smooth and uniform appearance.

 What pressure should the PEX tube be?

The recommended pressure for PEX (cross-linked polyethylene) tubes typically depends on the application and specific type of PEX used. In most residential plumbing systems, PEX tubes are designed to withstand a maximum working pressure of around 80 psi (pounds per square inch).

 What is the spacing for PEX supports?

The spacing for PEX supports largely depends on the pipe’s diameter and the specific building codes in your area. It is recommended to secure PEX tubing every 32 to 48 inches along its length.

 What are the 2 types of PEX?

There are two main types of PEX based on the production process:

  1. PEX-A (Engel method)
  2. PEX-B (Silane method)

 Which is best PVC or PEX?
