Professional plumbers usually work with meticulous details to avoid surprises. You should too. Cast projections and vertical drawings that use official hydraulic symbols is quite easy.

Drawing detailed drawings will save time and costs in the future. In addition, drawing a project helps you think carefully about your work, allowing you to see something that you might otherwise miss. It is almost certain that you will minimize additional trips to the store with water and wastewater products. A clear professional quality plan will make your first meeting with the construction department more productive.

How to draw plans

The plan for a new plumbing installation begins with a map of an existing plumbing installation. Use color codes and these commonly recognized symbols in your drawings to clearly highlight each element of your plan with plumbing risers.

If you have architectural drawings, make some photocopies. Otherwise, make several copies of the exact drawing of the scale of the room. A rectangular ruler will help you draw parallel lines. You will also need colored pencils, an eraser and a triangle of 30-60-90 degrees. Use grid paper and set the scale, for example 1/2 inch equals 1 foot. Drawing on the scale makes it easier to detect problems with the system. It also helps estimate materials. For more visit MEP Engineering.

To make a plan, first draw all the devices to the size of the scale and make sure they are not too close to each other. Insert the drainage ducts and ventilation openings for the devices, and then add the power cords. Prepare vertical drawings to show the vertical pipes.

Indicate the pipe sizes and the exact type of each accessory so that the inspector can validate them. Indicate the locations of the valves, including the stops on the devices and specify the type of valve. Make a shopping list of materials based on drawings.

Coding key

These are good ideas for coding the map. Show downspouts with continuous lines and high voltage lines with dashed lines. Point to vertical segments with notes in the top view. Mark hot and cold power lines with colored pencils, colored code caps and ventilation holes. Indicate pipe sizes with a curved guide line to avoid confusion of the pipe leader. Most likely, you will draw several versions of the plan before you get all the details.

DWV Elevation

The output-drain-discharge (DWV) elevation describes the route directed upwards, ventilations and renovations; duration of the execution of the corridor; and traps Its main objective is to show how the devices will be ventilated. You do not need to draw it in the architectural drawing.
Provide the drawing

The delivery figure shows the estimated length of the supply pipes. The main objective is to determine the minimum size of the pipes.
