PEX Plumbing Quiz

What is PEX used for?

• PEX (cross-linked polyethylene) is a type of flexible piping used for water supply lines in buildings, primarily for residential and commercial plumbing applications.
• It's a popular choice for radiant floor heating, snowmelt systems, and distribution piping.

Benefits of using PEX

• Resistant to freezing temperatures, scaling, and corrosion.
• More flexible than traditional copper or PVC pipes, making it easier to install and maneuver in tight spaces.
• Can withstand high water pressure and is less likely to burst or leak.
• Quieter and less prone to water hammer noise due to its flexible nature.
• PEX is also more resistant to scaling and mineral buildup, reducing the risk of pipe damage.

Types of PEX Fittings

• Crimp-style fittings: require a special tool to connect the PEX tubing to the fitting.
• Push-fit fittings: use a simple push-and-pull connection to connect the PEX tubing.
• Compression-style fittings: use a compression ring to secure the PEX tubing to the fitting.
• PEX-to-copper adapters: allow PEX tubing to connect to copper pipes and fittings.
• PEX manifolds: central distribution points that supply hot and cold water to various parts of a building.
