Plumbing System Components
Rough plumbing is the drain, waste and vent (DWV) piping and water supply piping that isn’t visible when construction is complete. Rough plumbing costs vary with the number of fixtures and length of the pipe runs. The figures in this section show rough plumbing costs for a typical single family home using plastic drainage and copper water supply materials. No plumbing fixtures, equipment or their final connections are included in these costs. See Plumbing Fixtures and Equipment for fixture and fixture connection costs. These costs include the subcontractor’s markup. Add the general contractor’s markup when applicable. For more complete information on plumbing and piping costs, see National Plumbing & HVAC Estimator at http://CraftsmanSiteLicense.com/ [view picture]

The figures above are from a time and money saving construction cost manuals from Craftsman Book Company. Over 50 cost estimating databases are available and all come with the popular National Estimator program.
