In sprinkler irrigation system, water is piped through one or more locations in the lawn which is then sprinkled over the lawn by over head high-pressure sprinkler guns. When water is passed to a sprinkler, it flows through the lateral lines and ultimately ends up in the sprinkler heads. The sprinklers have inlets in the bottom which are pipe thread inlets which allows the pipe to be thoroughly fixed with the sprinklers. The sprinklers are installed usually with the sprinkler head at the ground surface. When water is pressurized through them the pop out of the ground and water the desired area until the valve closes. When there is no water pressure the sprinkler heads will retract to the ground.
