Explore the detailed processing of understanding and interpreting a plumbing plan for a laundry area, emphasizing the important elements in the drawing like enlarged floor plans, gas lines, washing machines, sanitary lines, and riser diagrams. This article will walk you through the intricacies of such diagrams and how professionals handle missing information.
Key Insights
- The enlarged floor plan of the laundry area shows various elements such as dryers, washers, and gas lines of different measurements, essential for understanding the layout and connections.
- Interpreting the lines for hot water, cold water, and sanitary purposes in the washing machine section is vital. A professional will request additional information from the engineer if there's missing data, like the absence of sanitary lines from the washing machines.
- Riser diagrams reveal axonometric drawings, depicting images 30 degrees off a horizontal plane for an isometric view, beneficial for portraying the in-wall gas lines and washing machine connections in 3D, despite the drawing not being to scale.

This is the enlarged plumbing plan for the laundry. The drawing includes general notes and keynotes, some riser diagrams, and an enlarged floor plan. So let's begin with the enlarged floor plan.
We have dryers over here, and we have washers over here. You can see that there's a one-inch gas line which enlarges to a one-and-a-half-inch gas line and ultimately becomes a two-and-a-half-inch gas line. So it comes in here.
It remains two-and-a-half inches, though it might be a two-inch line here, even though it's not labeled—followed by a one-and-a-half-inch and then a one-inch gas line.
When we look at the washing machine, we can see that there are two different line types: one for the hot and cold water, and one for the sanitary. So there's a sink here that goes into the sanitary line.
Even though they're not shown, there are undoubtedly sanitary lines from the washing machines. In professional practice, when you find missing information on a drawing such as this—where they did not include the sanitary lines for the washing machines—you would submit a Request for Information (RFI) to the engineer. The engineer would then respond back with clarification, and it's all documented in the project records.

You can see that we have a floor drain that goes into the sanitary line, another floor drain, and a mop sink down here. So again, this is the source for the hot water and the cold water. They run over to the sink and the washing machines.
We have the gas lines at the dryers, and over here are the riser diagrams. Riser diagrams are axonometric drawings, meaning the images are drawn 30 degrees off the horizontal plane to represent them isometrically. And this is what an isometric drawing is.
It is scalable, even though they're saying that this particular drawing is not to scale. You can measure isometric drawings because everything is just shown isometrically. We can see the gas connectors.
We see the gas line. So the gas line is in the wall. It goes up and over through the ceiling.
Here are the riser diagrams for the washing machine. So again, we have the hot and cold water. We have notes indicating the size of the pipe.
The pipe then goes up to the ceiling and then departs from that general area. Drawings like these are always interesting and informative because you see things in plan, you see them isometrically, and you can understand them in both formats. So again, just remember that Revit does all of its work in 3D, and so it's very simple for the person assembling this drawing to have both a 2D and 3D isometric presentation.
I hope you've enjoyed this drawing. Let's go on to our next one.
