Class A PEX is the highest-rated PEX piping available on the market.
In its most advanced grade, this pipe can handle up to 497 psi.
Top manufacturers warranty piping for up to 25 years.
With a cross-linked development process, this PEX piping can withstand multiple occasions of freezing and extreme heat applications.
Class A PEX can be ordered in O2 (oxygen barrier), making it the perfect PEX for in-floor heating applications and domestic water lines.
Estimated life expectancy is 100+ years

Kitec Piping was installed in buildings between 1997 – 2005. Kitec is prone to corrosion and failure. Life expectancy is yet to be revealed.
Poly B™ piping was used as a replacement for copper piping. Due to their high rate of failure, their life expectancy rate is between 3 and 25 years.
Copper piping is commonly used in older water supply lines. They are resistant to corrosion and are reliable. The life expectancy is 50 years.
