PVC pipe is only approved for water service pipe, which is pipe from the water main to the structure. It is not approved for water distribution pipe within the structure. There is no distinction made between living space inside the home and a garage. Once the water pipe penetrates the wall or floor of a structure it becomes distribution pipe. Here’s how the difference between the two is defined in the International Plumbing Code (IPC) and the Florida Plumbing Code (FPC):

Water distribution pipe. A pipe within the structure or on the premises that conveys water from the water service pipe, or from the meter when the meter is at the structure, to the points of utilization.

Water service pipe. The pipe from the water main or other source of potable water supply, or from the meter when the meter is at the public right of way, to the water distribution system of the building served.
