Can you use PEX in commercial buildings?
PEX pipes. Cross-linked polyethylene (PEX) offers a unique benefit when used in commercial buildings. It is highly tolerant of heat and cold, and can, therefore, be used for different types of water supply applications. PEX is recommended for outdoor use because it reacts with ultraviolet light.
Can PEX be used for hot and cold water?
White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).
Is PEX pipe heat resistant?
For all PEX pipe and tubing, the maximum operating temperature is 200°F. No PEX should be operated at temperatures above 200°F for any length of time. The use of crosslinked polyethylene (PEX) pipe and tubing in high- temperature applications with operating temperatures above 180°F may affect the tubing’s design life.
Can you use PEX for furnace?
PEX pipe is cost-effective, flexible, durable and easy to install, making it a popular choice vs. copper and CPVC piping. Oxygen Barrier and PEX-AL-PEX tubing are intended for closed-loop heating applications (radiant floor heat, baseboards, etc.) Non-Barrier PEX is intended for hot and cold domestic water use.
Is it OK to use blue PEX for hot water?
PEX without an oxygen barrier is designed primarily for use in potable water plumbing systems. The color of PEX does not change any of the tubing’s ratings. There would be no problem, for example, using blue PEX for hot water lines or red PEX for cold water lines.
Why are PEX pipes used for radiant floor heating?
PEX pipe remains popular for radiant floor heating. While PEX use for water supply systems has been widespread in Europe since the 1980s, it was a latecomer here because some early versions deteriorated slightly when exposed to the high chlorine levels common in US water supplies.
What do you need to know about PEX tubing?
PEX tubing or piping is used for water supply lines as well as radiant floor heating. There’s been a lot of debate over PEX for the last several years because PEX has a few downsides that you might not expect. Here are some of the PEX pipe problems you’ll want to know about before making any decisions: PEX may leach BPA and other toxic chemicals.
Can a PEX boiler be used under the floor?
If it’s a gravity-fed system, you likely won’t be able to use this for under-floor heating. If it’s pumped-based, you will likely have to create a new circuit for this room. On top of that, you can’t just place the pipe under the floor.
What kind of pressure can a PEX pipe withstand?
PEX-a pipe can withstand a burst pressure of around 800 psi (almost two times the requirement for ASTM F876, the standard specification for PEX tubing). So neither the pipe nor the fittings are weak points, making for an extremely high-performing system in domestic water and hydronic piping applications. Q: Are the fittings freeze-resistant?
Where can I use PEX tubing in my home?
According to the latest information available, PEX tubing is approved for use in residential, commercial, industrial and institutional radiant heating applications everywhere across the U.S.
Is it OK to use PEX tubing for radiant heating?
According to the latest information available, PEX tubing is approved for use in residential, commercial, industrial and institutional radiant heating applications everywhere across the U.S. Although PEX tubing is approved by all major building codes and major model plumbing codes,…

Can you use PEX piping for compressed air?
Q: Can PEX piping be used for compressed air? A: From a listings and warranty standpoint, it cannot. However, many people do use it for compressed air because of its high burst pressure. Unfortunately, manufacturers usually cannot warranty the piping under those circumstances. Q: Why is the domestic hot-water return velocity so low?
