How Do In-Ground Sprinklers Work?

In-ground sprinkler systems are the best and most efficient way to water your landscape without wasting valuable water.

Because sprinkler heads are strategically placed and the water output is carefully timed, in-ground sprinkler systems give you the utmost control over how and when your yard is watered.

While the benefits of an in-ground watering system are evident, many potential buyers wonder not why they should invest in an irrigation system, but rather how do in-ground sprinklers work?

Garden view of how do in-ground sprinklers work.

In-ground Sprinklers: The Basics

In a typical system, a network of retractable sprinkler heads is buried about 12 inches below the surface. Each sprinkler head is strategically placed based on the sun exposure, elevation and zones of the surrounding landscape. Water is carried throughout the pipe by way of a pressure system that works as follows:

In-ground Pressure Systems

1.) An electronic controller tells the water valves when to open and when to close. 

2.) Once activated, water is pushed through the pipe and forces the sprinkler head above ground. 

3.) When the water pressure stops, the head retreats back underground.

In-Ground Water Sources

So pretty simple, when the controller is activated, water is released and the sprinkler begins. But where does the water come from? In-ground sprinkler systems pull their water from one of two sources. This is the major differentiator between a pump system and a metered water system.

  • Pump systems pump water into the sprinkler from a body of water, like a lake or a pond. This allows homeowners to service their system without taking on additional water costs.
  • Metered water systems are usually tied to the home's existing  water lines and are serviced by the local utility department. While this involves additional water costs, the service can be more reliable than a pump system. 

To really grasp how do in-ground sprinklers work, you must understand that everything begins and ends with the controller.

The above-ground controller is attached to a set of water valves at the start of the system. This initial set of valves is where the main water source enters the system before it is distributed to the rest of the sprinklers.

The controller is designed to release each valve individually, telling the valves when to open, how much water to release and when to turn off. Automatic controllers follow this process automatically, while less expensive manual controllers turn on and off with the push of a button.

Advanced Features of Modern Controllers

Understanding the Controller

The controller is more than an on/off switch—it’s the brain of the system. Today’s controllers offer:

  • Weather Sensors: Automatically adjust schedules based on rainfall or temperature.
  • Smartphone Integration: Allows remote control and monitoring of your sprinkler system.
  • Zone Customization: Tailors watering times and flow rates for each part of your yard.

This level of control not only saves water but also ensures your lawn and garden receive consistent care.

The Role of Sprinkler Heads in Water Distribution

Understanding how sprinkler heads work can help homeowners appreciate the precision of in-ground systems. These heads are designed to:

  • Pop-Up Action: When the system is activated, water pressure raises the heads above ground to distribute water.
  • Coverage Control: Adjustable nozzles allow targeted watering to avoid over-saturating or missing certain areas.
  • Efficiency: Modern sprinkler heads reduce water waste with features like low-angle spray patterns or drip emitters for delicate plants.

Each sprinkler head is strategically placed to account for sun exposure, landscape elevation, and plant type, ensuring optimal performance.

Pump vs. Metered Systems: Which is Right for You?

While the basics of how does a sprinkler work remain the same, the water source significantly impacts system efficiency:

  • Pump Systems: Great for properties near lakes or ponds. These systems are cost-effective but may require additional maintenance to address fluctuating water levels or debris.
  • Metered Systems: Ideal for urban areas with reliable municipal water lines. While they come with utility costs, these systems require less upkeep.
