Spec Plan G: Plumbing

what you need to do —

Identify any special plumbing needs by room:

— utility sink in garage
— wet bar in recreation room
— plumbing for unfinished basement, etc.

  • Start the plumbing when the house has been "dried" — windows, doors, and roof installed.
  • There are many new plumbing materials that can reduce your cost. See below for information.


If your lot has access to public sewer systems,

  • you will need to connect to it. If not, you will be installing a septic tank system.
  • sewer systems work with the flow of gravity — your lowest sink and drain, situated in the basement for example, must be higher than the sewer line.


Tubs, toilets, basins, and showers may be installed at this time.

  • If not, plumbing to the point of connection needs to be double checked so that there won't be any surprises.
  • Your water heater may also be installed during this phase. Check out the new water heating systems before you complete your plumbing specifications.
