It's flexible, resistant to freezing, and less prone to scaling and corrosion than some traditional materials.

PEX Water Line Installation in Gaithersburg, MD
PEX (cross-linked polyethylene) piping is a modern, flexible, and very popular choice for water line replacement. It resists corrosion, scaling, and chlorine, making it very durable for most water conditions. Disconnecting garden hoses and shutting off outdoor spigots before the first hard freeze heads off many burst-pipe calls each winter. PEX can expand and contract without bursting, which is a real advantage when a cold snap hits Gaithersburg. Its flexibility allows for fewer fittings and faster installation.
