Frequently Asked Questions β€” Plumbing Rough-Ins in Wilmington

What is included in a plumbing rough-in?
A rough-in includes all drain, waste, and vent piping plus water supply lines installed within walls, floors, and ceilings β€” before insulation and drywall. Everything is positioned precisely for the finish fixtures.
How do I schedule a rough-in for a new build?
