Clocks are used to schedule irrigation systems. This term is interchangeable with timer or controller. See also, Timer.


Heads hold nozzles, which emit water. They are split into three major categories: spray heads, rotary heads, and bubblers.

Index valve

An index valve delivers water to all zones, eliminating the need to install individual electric solenoid valves. See also, Solenoid.

Irrigation System

Irrigation systems are a network of devices designed to bring water to your landscape. The term “irrigation system” encompasses sprinkler systems, drip irrigation systems, and more. Although all sprinkler systems are irrigation systems, not all irrigation systems are sprinkler systems.


This term isn’t used in irrigation. See, pump


Pipes are used to deliver water from the pump to each zone.


Irrigation pumps provide water to a section of land. Sprinkler pumps provide water to zones or areas by way of valves.


Nozzles emit an even spray of water across a section of your landscape. This creates a superior coverage area.

Smart Timer

Smart timers use satellite technology to predict weather conditions. This helps you schedule your irrigation system more efficiently. Wi-Fi can be added to control the timer from anywhere in the world using a cell phone. See also, Clock.


Solenoids open and close valves. In some systems, the individual solenoid valves are replaced by an index valve. See also, Index valve.


Sprinklers are the water-emitting end of an irrigation system. They spray water onto the lawn.

Sprinkler System

Sprinkler systems are a network of devices that water your landscape. They are distinguished from other irrigation systems by their use of sprinklers.


Valves direct water to different zones or areas.
