Plumbing Lines and electrical Wires
You may need to dig up the floor to lay out piping for a new water line especially if you have to move the drainpipes to accommodate a new location for a fixture.
The electrician does all the behind the walls work by roughing in electrical switches and outlets and venting and heating on the walls. The electrician then runs the wiring to the boxes and back to the power panel but doesn’t turn on the power just yet.
Getting Code Work Approved
While the walls are still open and you can see any new plumbing and electrical work, local buildings inspectors must visit the site and inspect the work. If all the work meets local building code, you can insulate the walls and close up the walls. Applying standard drywall works well in most spaces however green board of moisture resistant drywall should be used in bathrooms. Seal the joints between panels with several coals of drywall compound.
Next, hook up the new receptacles and electrical outlets as well as heating and coding lines and lighting and venting systems.
The local building department will make a final inspection and sign off on the job.
