Since most water is carried to houses through copper pipes, yeah.
Copper pipes are very durable and most advised.
Copper pipes are used for plumbing. They are usually in interior walls or the basement. Typically, at least here in the North east, you would try to keep them out of exterior walls to keep them from freezing.

Copper is used as hot water pipes because the copper will not corrode when the hot water goes through the pipes
To connect PEX tubing to copper pipes, you can use a fitting called a PEX-to-copper adapter. This adapter has a PEX side that can be crimped onto the PEX tubing and a copper side that can be soldered onto the copper pipe. This creates a secure and watertight connection between the two types of pipes.
You can use pvc pipes in some applications,but copper is far better for household uses.It's not that expensive when you consider how well it does the job.
