Introduction • The plumbing plan shows the location, size, and type of all plumbing equipment. – Shows the complete plumbing system. – Shows water supply lines, waste disposal lines, and plumbing fixtures. • Gas lines and built-in vacuum systems may be included on the plumbing plan. • The plan should be coordinated with the electrical and climate control systems. 7 © Goodheart-Willcox Co. , Inc. Permission granted to reproduce for educational use only
Required Information • The plumbing plan should include: – Waste lines and vent stacks. – Water supply lines. – Drain and plumbing fixture locations. – Size and type of pipe to be used. • Use proper plumbing symbols. • Include a plumbing fixture schedule. 8 © Goodheart-Willcox Co. , Inc. (continued) Permission granted to reproduce for educational use only
Required Information • • Add notes to describe the system. Show the outline of all plumbing fixtures. Determine and show clearance dimensions. Locate plumbing fixtures where access may be provided for servicing. • A plumbing plan is required for each floor of the house. 9 © Goodheart-Willcox Co. , Inc.

Waste Lines and Vent Stacks • The waste line network is usually designed first and then the system is planned around it. • Each water closet must have a main stack. • A sufficient number of secondary stacks must be included to vent other fixtures. 10 © Goodheart-Willcox Co. , Inc. (continued) Permission granted to reproduce for educational use only
Waste Lines and Vent Stacks • Figure 25 -1 in the textbook shows the minimum sizes for residential waste and vent lines. • Draw waste lines and vent stacks with a wider line than that used for supply lines. • Show the required slope of waste lines on the plan or in a note. 11 © Goodheart-Willcox Co. , Inc.

Drawing Water Supply and Waste Lines • Water supply and waste lines vary in width and are represented by different linetypes (symbols). 12 © Goodheart-Willcox Co. , Inc. Permission granted to reproduce for educational use only
Water Supply Lines • The water supply begins at the city water main or private water source. • Show the building main on the plumbing plan. • Show proper shutoff valves, meter, and size of pipe. • Show any required water softener, filter, or storage tank positioned along the building main. 13 © Goodheart-Willcox Co. , Inc. (continued) Permission granted to reproduce for educational use only
Water Supply Lines • A typical arrangement where a water storage tank, water softener, and water heater are required. (continued) 14 © Goodheart-Willcox Co. , Inc. Permission granted to reproduce for educational use only
Water Supply Lines • Show and identify the water heater. • Show hose bibs and other fixtures that do not require softened or filtered water. • Identify each fixture that requires a water supply and note the size of pipe. 15 © Goodheart-Willcox Co. , Inc. Permission granted to reproduce for educational use only
Drain Locations • Basements and attached garages usually have floor drains. – Usually connected to the storm sewer or dry well. • Indicate drains with the proper symbol. • Show pipe leading to the storm sewer or dry well. 16 © Goodheart-Willcox Co. , Inc. Permission granted to reproduce for educational use only
Size and Type of Pipe • Several factors affect the size of pipe needed for a given installation. – Average amount of water used. – Peak loads. – Water pressure on the line. – Length of pipe run. – Refer to the minimum pipe sizes shown in Figure 25 -1 in the text. 17 © Goodheart-Willcox Co. , Inc. (continued) Permission granted to reproduce for educational use only
Size and Type of Pipe • Specify the type of pipe to be used throughout the system. • Check your local code to determine the types that are acceptable in your area. • Copper pipe is a popular choice for the water supply system—Type L. • Nominal diameter refers to inside diameter of copper pipe. 18 © Goodheart-Willcox Co. , Inc. Permission granted to reproduce for educational use only
Plumbing Fixture Schedule • A plumbing fixture schedule is useful in planning the plumbing system, ordering the plumbing fixtures, and installing the system. • Normally indicates: – Identifying symbols. – Names of plumbing fixtures. – Number of fixtures required. – Pipe connection sizes. – A space for remarks. 19 © Goodheart-Willcox Co. , Inc. (continued) Permission granted to reproduce for educational use only
Plumbing Fixture Schedule • Typical plumbing fixture schedule. 20 © Goodheart-Willcox Co. , Inc. Permission granted to reproduce for educational use only
Plumbing Symbols • Use standard symbols when possible. – Standard symbols are recognized and accepted. – When a nonstandard symbol must be used, explain it in a legend. • Place the legend on the sheet where the symbols are used. • Some symbols are not drawn to the exact size of the feature that they represent. 21 © Goodheart-Willcox Co. , Inc.

Plumbing Symbols • Commonly accepted plumbing symbols. 22 © Goodheart-Willcox Co. , Inc. Permission granted to reproduce for educational use only
Notes • Notes are used to describe: – Installation procedures. – Materials. – Any other facet of the plumbing system. • Notes appear on the drawing to which they refer. 23 © Goodheart-Willcox Co. , Inc. Permission granted to reproduce for educational use only
Manual Drafting Procedure • Gather all the information that you need before beginning to draw the plumbing plan. • Sequential Steps 1. Trace the floor plan showing features that relate to the plumbing plan. 2. Draw the symbols for all plumbing fixtures that are to be connected to the system. 24 © Goodheart-Willcox Co. , Inc.
