Modern plumbing systems often use crosslinked polyethylene (PEX) A and PEX B pipes. Each type has its pros and cons.
We’ll explore the features of PEX A and PEX B pipes. This will help you choose the right one for your plumbing systems.
This is a detailed close-up of two types of crosslinked polyethene (PEX) pipes side by side, one labelled PEX A and the other PEX B, showcasing their distinct textures and colours. The background features a soft-focus plumbing installation scene, highlighting the versatility and applications of PEX in modern plumbing systems.
Understanding PEX: What is It?
PEX is a flexible and tough plumbing material made of crosslinked polyethene. It is used in water supply systems.
PEX was first used in Europe in the 1960s. It has many benefits over copper and rigid plastic pipes.
PEX can handle high heat and pressure. It’s great for hot and cold water lines.
This piping resists corrosion, scaling, and bacteria. It ensures a reliable water delivery system.
PEX is used in homes and significant buildings. It’s popular with homeowners, contractors, and plumbers.
The Differences Between PEX A and PEX B
PEX A and PEX B are two types of plumbing pipes. Their different features affect their use in plumbing systems.
PEX A is made using peroxide, making it tough and bendy. PEX B uses silane, which is cheaper but less flexible.
PEX A has more crosslinking, making it better for high heat and pressure. PEX B has less crosslinking, making it suitable for everyday use.
PEX A bends easily, making it great for tight spaces. PEX B is stiffer, which can be good in some plumbing jobs.
Advantages of PEX A
PEX A piping offers many plumbing benefits. Its flexibility allows it to bend easily, making installation simpler.
PEX A resists kinks well. This means it can handle sharp turns without damage.
The pipe has a unique shape memory property. It can return to its original form after being bent.
This feature helps when adjusting plumbing layouts. It makes the installation process more adaptable and efficient.

PEX A’s features make it great for many plumbing uses. It needs fewer fittings, creating a more straightforward plumbing system.
These qualities can lead to cost savings. Both homeowners and contractors can benefit from using PEX A.
Advantages of PEX B
PEX B pipes are a top pick for plumbing. They cost less than other pipe types.
This makes them great for budget-friendly projects. Homeowners and builders love the savings.
PEX B resists chlorine very well. This helps pipes last longer in areas with chlorine-rich water.
It cuts down on repairs and replacements. Your plumbing stays strong for years.
PEX B keeps its shape in all conditions. It doesn’t change size with heat or pressure.
This makes the pipes more reliable. They work well in places with changing temps.
PEX B is loved by many in the plumbing world. It’s great for new builds and fixes.
Drawbacks of PEX A
PEX A piping has some drawbacks. Due to its complex manufacturing process, it costs more than PEX B piping.
This higher cost can put some homeowners and plumbers off. It may not fit well with tight budgets.
PEX A is also sensitive to UV light. This UV sensitivity can weaken the pipes over time.
Outdoor pipes need extra care to protect them from sunlight. Shielding or insulation may be required for long-lasting pipes.
PEX A has more expansion concerns than PEX B. Careful planning is key to avoiding pipe damage or leaks.
When picking plumbing material, these issues require careful thought. Understanding them can help you make the best choice for your needs.
Drawbacks of PEX B
PEX B piping has some drawbacks. Its reduced flexibility can make installation tricky in tight spaces.
Some studies show that PEX B may fail more often in certain conditions. High temperatures and UV light can cause problems.
PEX B can become brittle due to oxidation over time. This may lead to cracking and increase the risk of leaks.
Despite these issues, PEX B is still popular for many plumbing jobs. It’s often used in homes and light commercial buildings.
When choosing pipes, compare PEX B to other options. Consider PEX A, copper, or PVC for your project needs.
Making the Right Choice: PEX A vs PEX B
Choosing between PEX A and PEX B pipes can be tricky. Think about your plumbing project considerations and pipe selection criteria.
Look at your project needs first. PEX A and PEX B have different pros and cons.
Check how each pipe works in your setup. Think about temperature, pressure, and where you’ll use it.
Don’t forget about your budget. PEX A lasts longer but costs more than PEX B.
Weigh the long-term benefits against what you can spend. Ask for professional advice if you’re not sure.
