They stay well above the ground so the water is not blocked by large foliage.

How does a lawn sprinkler work. Electric valves in a sprinkler system are turned on and off by the controller. Sprinkler heads in a garden are usually a raised head type. Controllers are computerized timing devices that automate the watering of a lawn.

When it shuts off so does the water. A lawn watering system needs a pump pipes valves and a sprinkler head. An irrigation system uses sprinkler valves also called irrigation valves to control water flow to your lawn.

The controller itself can be located indoors and remotely wired to the valves outside. Water coming from the pumps goes through a pipe in which the water runs under pressure and it is sprayed through a nozzle or a sprinkler head. Pressurized water runs through them and it sprays in the air.

When the water pressure stops they retract back down to ground level. These valves come in various models that maintain an adequate water supply to the various control zones you have setup across your lawn and garden. The sprinkler heads work on a pressure system that when the water goes through the pipe it pushes them up above the ground.
