PEX is cross-linked polyethylene tubing. The material is more durable under temperature extremes, chemical attack, and better resists creep deformation, making PEX an excellent material for plumbing systems, hydronic radiant floor heating, snow melting applications, refrigeration, etc. It is flexible, making it easy to install and service as well as quiet in operation. It can withstand the high and low temperatures which means fewer fractured lines from freezing. It’s smooth interior, fewer joints and chemically resistance qualities reduce corrosion, chance of leaks, and extend the life of the systems with less maintenance relative to copper-based systems. The manifold-direct line supply system can substantially reduce water and energy consumption because dedicated supply lines do not purge as much water to receive hot water at a fixture. This style of system also provides flexibility in sizing lines resulting in additional usage efficiencies. Collectively, these attributes save costs related to installation, system materials, water usage, energy consumption, and maintenance - all while delivering easier installation, and cleaner, quieter, faster hot water.
