Draw Riser Diagram
By: Tim Carter
You need to draw a riser diagram to get a plumbing permit. This drawing is a good idea because it proves to the plumbing department that you have a clear idea of the correct pipes to put in your home.
You should follow all of the code requirements in the Uniform Plumbing Code when you draw your riser diagram. A building inspector will FAIL your drawing if you draw the wrong drain, waste, and vent pipes.
What Does a Riser Diagram Look Like?
A riser diagram is a three-dimensional drawing that shows all the drain, waste, and vent pipes in a home or business. The pipe sizes are all shown on the drawing.
It is a good idea to have general notes on the drawing that speak to the slope of drain pipes, the height of toilet flanges above a finished floor, and the proper way to support pipes so they don’t act as beams.
Who Draws Riser Diagrams?
I happen to draw them. I love doing it. I’ve been a master plumber since 1981 and to me drawing a riser diagram or plumbing isometric drawing is like solving a crossword puzzle.

What do Riser Diagrams Show?
A riser diagram for plumbing drain, waste, and vent (DWV) piping shows:
- all drain pipes
- all waste pipes
- all fixture vent pipes
- the building drain
- general notes
- pipe sizes
- code-approved pipe connections
How Long Does it Take to Draw One?
I can draw a riser diagram in as little as 24 hours if you have an emergency. It normally takes five business days to draw a riser diagram because of the other orders already in the queue.
Mechanical engineers might take weeks to produce this drawing.
Are Building Drain Layouts Important?
Yes, a building drain layout is very important. Non-plumbers almost always install the wrong fittings that cause serious clogs.
If you’re a DIY plumber, you should seriously consider asking me to draw your Building Drain Layout drawing.
Where Can I Get DIY Phone Coaching Help?
I offer DIY phone coaching. I’ve helped many homeowners over the phone install all the pipes in their homes. My favorite job was helping Zoe, a 28-year-old woman, in New Mexico with all the plumbing in her rural new home.
You can hire me for 15 minutes at a time and do either a voice or video call. Using video, I can see exactly what you’re up against to give you the best advice.
