Are there different system to choose from?

Although every system should be tailored to meet your individual needs, a typical system will be comprised of a controller (which functions as the brains of the system), valves (which open and close to release and stop the flow of water to underground pipes) and sprinklers (which actually distribute the water to a given area). It's best if all components of a system are manufactured by the same company in order to ensure that they are designed to work well together.
