Plumbing Rough In

Rough in plumbing is, as its name suggests, basically a “rough draft” of your plumbing installation. The point is to get a diagram of your plumbing in place, a static and unchanging framework upon which you’ll complete your plumbing installation. This is beneficial because, once your rough in is approved, you can move forward with your construction or remodel installation without having real plumbing pipes getting in the way, but you’ll still know exactly where those pipes will be going once the project is ready for them.

The waste-water system is usually installed first. This is because it is always easier to work smaller pipes around larger ones, than the other way around. All waste-water pipes must be angled downward, towards the septic outlet and away from plumbing drains.

The waste-water system must be vented, to permit waste-water to flow smoothly and allow for the escape of methane gas. This requires the plumbing system to have a pipe that extends upward, though the roof, and vents outdoors. Each plumbing fixture is required to have its own trap, or a U-shaped pipe that will remain filled with water, to prevent sewer gas from entering the living space.

The main cold water pipe supplies water to the individual lines that supply water to the fixtures throughout the house. Supply pipes are typically PVC.

Now that you have your plumbing roughed in and all the sheets and walls are up, it’s time for fit off. This is the fun part, where the tap ware, bath and toilets you’ve picked out are installed.
