This guide is intended to be used when designing and installing small single family residential sprinkler systems. It is set up in an easy-to-follow format with illustrations and helpful charts.

If this is the first system you have installed, or if you have installed several systems but have never used this guide before, we recommend you look through the next few pages and become familiar with this presentation of the design and installation process.

You will notice we have included a sheet of graph paper for your convenience. There are detailed illustrations depicting suggested installation methods for sprinkler heads, pipe and valve manifolds, and how to connect the sprinkler main line into the house water system. Installation tips have also been placed throughout the guide to assist you in planning a system. A Glossary of Terms is included.

While developing the Gallons Per Minute (GPM), Working Pressure, and Pipe Sizing charts, we considered reasonable friction loss and acceptable water velocity for a residential irrigation system. If you have any questions on the design or installation process, your best resource is your local Hunter distributor.

Hunter recommends contracting the services of a professional irrigation designer when planning large residential or commercial projects. Contractors and irrigation designers can receive additional information by contacting their local Hunter distributor.
