PEX plumbing is a type of flexible plastic piping that has been gaining popularity recently as an alternative to copper and galvanized piping. PEX stands for cross-linked polyethylene, which is produced by linking polymer molecules in polyethylene, increasing its flexibility and durability. PEX piping was first used for radiant floor heating in the late 1960s and started appearing in homes and new construction in the U.S. in the ’80s and ’90s.
PEX piping has many advantages over traditional piping materials, including:
- Ease of installation: PEX piping is easy to install, and for many minor DIY projects, it doesn’t require a plumbing license to do your own installation.
- Efficiency: PEX pipes have a smaller diameter than other types of pipes, so the wait for hot water is shorter, resulting in less waste of water. Additionally, PEX material has greater thermal conductivity properties than other types of pipes, which reduces heat loss.
- Quiet operation: PEX pipes do not rattle, so you won’t have to worry about noise.
- Affordability: PEX is manufactured with far less expensive raw materials than copper.
- Sustainability: PEX has a low carbon footprint, in terms of sourcing and production.
- Acid-resistant: Unlike copper, PEX can withstand acidic water.
- No mineral build-ups: Mineral scaling will not build up in PEX piping.
- Less water turbulence: PEX creates far less water turbulence, which means the water flows more efficiently through the PEX pipe. The result is less water can actually provide the same amount of water pressure at the end use.
PEX piping is used for water supply lines and radiant floor heating tubing. It is freeze-resistant, which means that it can withstand freezing temperatures, making it a benefit over copper and other types of plumbing. PEX piping is also ideal for water distribution systems of all sizes and complexities.
