Yes! Choosing to use PVC as your underground conduit is one of the most recommended options when it comes to choosing a conduit.
PVC is generally considered to be an affordable, flexible, and strong underground conduit.
It may not be the prettiest option, but since it will be underground, the only person who will see it is you when you install it!
PVC also does not disrupt the signals in your system significantly while there is likely to be more signal interruption when a metal conduit like steel, is used.
