Is Uponor PEX chlorine-resistant?

Answer
In recent years, ASTM F876 and ASTM F877 have been refined to incorporate benchmarks for chlorine resistance. Under certain conditions, a high concentration of chlorine can contribute to the oxidation of plastics. This, in turn, can affect service life. The upgraded ASTM standards provide an additional level of assurance that PEX tubing manufactured to these standards can withstand the potential oxidative effects of heavily chlorinated water.

What's the difference between PEX and PVC?

Answer

Crosslinked polyethylene (PEX) and chlorinated polyvinyl chloride (CPVC) are both used for plumbing systems. The PEX manufacturing process chemically joins individual polyethylene molecules through an extrusion process to create a highly flexible tubing product. With CPVC, the manufacturing process starts with PVC resin and adds additional chlorine molecules, which creates a much more rigid tubing product.

While both products are listed to their own respective ASTM standards for use in plumbing systems, PEX provides superior features, installation characteristics and longevity. For example, PEX systems offer:

- Reliable and visual connections

- Flexibility resulting in tighter bend radius

- Quick and simple fitting connections

- Safe air testing

- Fewer fittings
