Sample Irrigation Installation Detail Drawings

by Jess Stryker

These sample drawings show some possible ways of putting your irrigation components together. They show methods typically used in the industry, although you need to use common sense and make modifications as needed for your specific situation.

SAMPLE PLANS ONLY, NOT FOR CONSTRUCTION. These sample drawings must be carefully reviewed and modified as needed to fit your specific irrigation system project and location. By using them you agree to review and modify the sample plans as needed, you also agree to be subject to the terms of use listed at, including the agreement and limit of liability. See the paragraph below regarding copyrights. Due to licensing laws regulating designers (ie; landscape architects and irrigation consultants) the Sample Plans must have the note "Not for Construction" on them unless the designer's name, license number if applicable, signature, and the date signed are shown. If you are using the sample drawings for your irrigation system, then you are the designer.
