I am planning to build a new workshop (see attachment) and do not want exposed dust collection pipes. My choices are:
1. To build 6" walls so I can run metal pipes in the walls (higher cost)
2. To build 4" walls and put PVC pipes underground.
Can the latter be done? Since the PVC lines would be underground, I assume there would be no need to ground them.
Has anyone run underground PVC dust collection pipes? Any advice or comments?
