Where should you not use PEX?
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.

Examine each pipe for burrs, nicks, cracks, or damage; then remove them with a razor blade on the PEX or sandpaper on the CPVC side. A smooth, finished end on the end of whatever sort of pipe is put into the fitting is essential for proper seal. Place the push fitting on the CPVC pipe and firmly press it against the pipe until the latter cannot be inserted any further. Since CPVC is a more stationary pipe, it is fitted first. Move the end of the PEX tubing over to the other side of the push fitting and press it firmly and fluidly into the fitting. Turn on the water and check for leaks.
What is PEX pipe?
Medium- or high-density polyethylene is used to make PEX pipes, which are flexible and sturdy. For decades, PEX piping has been utilized in hot-and cold-water distribution systems as well as hydronic radiant heating in Europe. The United States was introduced to PEX pipe in the early 2000s. In the 1980s, PEX is the most widely used flexible piping for plumbing and radiant floor heating applications. PEX tubing is easy to work with because it can be easily snaked through the walls, making it a common selection for remodels. Water distribution pipes made of PEX tubing are compatible with all major plumbing codes, making it an excellent choice for your house. Learn what happens after the PEX manufacturing process is complete.

What is CPVC water?
CPVC (chlorinated poly (vinyl chloride)) is a durable and resilient thermoplastic material that’s commonly used for hot and cold potable water applications in residential construction . Because it’s made of polyvinyl chloride, CPVC is resistant to damage from highly chlorinated domestic water and has a greater temperature tolerance than PVC. Before your home’s water reaches you, public water companies employ chlorine-based disinfection to destroy pathogenic bacteria. Disinfection methods and levels in water systems can differ somewhat without notice, depending on your location and season. Corrosion resistance is CPVC’s primary advantage over PVC.

Harvel CTS CPVC pipe can be connected to copper, brass, valves, and other piping materials using transition unions, compression fittings, specilty reinforced male and female adapters, and other readily available transition fittings. Follow the fitting manufacturer’s installation instructions for the specific connection being used to ensure a proper leak-free joint. When using compression fittings utilizing brass ferrules, it is recommended that Teflon® tape be wrapped around the ferrule prior to assembly to help compensate for differences in expansion rates between CPVC and metallics. Teflon® tape is also the recommended thread sealant for threaded connections. Certain pipe joint pastes and sealant compounds contain substances which could be damaging to CPVC and result in system failure. If joint sealant other than Teflon® tape is used, contact the sealant manufacturer for compatibility with CPVC. Caution must be exercised to prevent overtightening of threaded connections and compression fittings.
