Consider using flexible PEX piping on your next plumbing project. It's easy to manipulate and installs quickly and economically.
PEX piping's ease of use makes it perfect for do-it-yourself plumbing projects.

PEX can bend in any direction and will remain in a fixed position. Use a metal tube like this to prevent kinks when tight bends are required
Unlike rigid piping that uses a straight-line network of pipes to deliver water to appliances and fixtures, PEX delivers constant pressure to all fixtures by directing water in one central tube to a hub, where water is then equally distributed in half-inch lines throughout the house.

To learn how to connect PEX piping to existing copper pipes, see “Connecting to Copper.”
For small jobs, compression fittings are the least expensive way to join PEX piping.
Crimp-on connection rings are the most economical way to make a large number of PEX connections, but the crimping tool can cost several hundred dollars.
This crimping tool, which can cost several hundred dollars, is necessary to make PEX connections using crimp-on connection rings.
Valves and T-connections can be installed in PEX much more easily than in rigid piping.
Tools of the trade: A reaming tool (left) imparts a perfectly round shape to the inside of the PEX line, ensuring good connections. A specialized cutting tool supports the round profile of the plastic tube.
