PEX piping is flexible, resists scale and chlorine deposits, doesn’t corrode or develop pinhole leaks, is less labor intensive to install than metal or rigid plastic, and has fewer connections and fittings. PEX Piping can make turns up to 90 degrees without the use of a coupling. It also comes in spools, so it can be installed on long runs avoiding the use of couplings. With less connections you reduce the possibility of leaks in the future. Additionally, PEX Piping does not transfer heat as easily as copper piping, and is durable from below freezing to 200 degrees Fahrenheit.
PVC/CPVC Pipe is a common material used for household drainpipes, vents and water lines. PVC/CPVC pipe is a popular solution because of its durability against leaks and resistance to root intrusion. Many homes have connections from the street to the house using PVC/CPVC piping.
Copper is a long lasting solution to problems such as: plumbing leaks, better quality water and water pressure improvement. Replacing some or all of your plumbing with copper piping is typically the most expensive type of repipe. There are many benefits to using copper, but because of the high cost of copper, along with the labor of installation and drywall repairs associated with this type of improvement, often it can be to costly to repipe with copper.
