Copper pipe for long term
This Copper pipe is great for indoors or outdoors in non-freeze states, in freeze states it is best to use PEX pipe which will allow for expansion from colder climates.
Copper Pipe is a popular choice for water lines. It is joined using a sweat, roll grooved, compression or crimped/pressed connection. Copper pipe is rigid due to the work hardening of the drawing process which cannot be bent and must use ''elbow fittings'' to go around corners or around obstacles, however a pipe bender can be used for small bends or off sets.
